Unique Sensor Film Minimizes Defects and Improves Quality in Wafer Bonding

Pressurex® Shows Pressure Distribution and Magnitude of Contacting Surfaces in Bonding Fixtures

Pressurex® film from Sensor Products Inc. is a quick, accurate and economical way to detect and correct pressure variations which can result in flaws (defects) in the wafer bonding process. When placed between contacting surfaces, it instantaneously and permanently changes color directly proportional to the actual pressure applied. With Pressurex®, variations in pressure that lead to imperfections (or irregularities) in the bonding process can be accurately detected and corrected -- improving yield, decreasing scrap, and boosting productivity.

In wafer bonding, two flat substrates are permanently joined together by applying carefully calculated pressure, temperature, and voltage. Of the three parameters, pressure is often the most difficult to precisely ascertain and control. Traditional methods assume perfectly flat pressure plates. However, in nearly all real environments pressure plates are not ideal due to manufacturing or installation variability and degradation over time from wear. The result is difficult to detect pressure variations across the surface that can lead to un-bonded wafer areas, cracked wafers, and premature wear of the pressure plates.

Pressurex® systematically measures pressure across the entire pressure plate. When placed between contacting surfaces of the wafer bonding fixture, the film instantaneously and permanently changes color directly proportional to the actual pressure applied. Precise pressure magnitude is easily determined by comparing color variation results to a color correlation chart (conceptually similar to interpreting Litmus paper). Additional pressure analysis of the film is available which assimilates the pressure distribution into 2-D and 3-D pseudo color images, histograms and line scans among other features.

Micralyne Inc., an independent foundry located in Canada, uses Pressurex® to adjust the compression exerted by their bonding tools.  Early testing of bonding results analyzed with the film reveals a donut shaped high pressure ring with relatively little pressure applied to the center ((left)). After a series of adjustments the final result is a more uniform distribution of pressure (right).

Wafer-to-wafer bonding has become an enabling semiconductor technology in industries such as 3D packaging, MEMS, MOEMS, and SOI. Pressurex® is being used across a wide range of bonding technologies, including metal eutectic, anodic, fusion, metal diffusion, glass frit, and polymer adhesive bonding

The “snapshot” imaging results of Pressurex® can be used as a control to compare processes and tools, making it ideal for six-sigma and other closely monitored high performance manufacturing operations.

Pressurex® measures pressures from 2 - 43,200 PSI (0.14 - 3,000 kg/cm2).   For a free sample in your desired range, contact Sensor Products Inc. visit our website at where you can view the entire line of products and applications.

TDK-Lambda Expands Quarter Brick Line

TDK-Lambda has expanded its impressive line of high power quarter brick modules with the introduction of the iQL and iQG Series. Available with nominal output voltages from 2.5V to 12V and power ratings up to 300-watts, these wide input range fully-regulated and isolated DC-DC converters deliver exceptional performance in the industry standard DOSA quarter brick footprint.
The iQL/iQG Series has been designed with confined space and demanding thermal environments in mind as required in Telecom, Datacom, Wireless and many other applications including Test & Measurement, Broadcast, Robotics and Industrial Controls. These single board open-frame converters offer up to 95% efficiency, 181W per cubic inch power density and up to 60A of useable output current. Metal baseplates are provided on most models to facilitate conduction cooling when needed.
By integrating TDK's latest custom ASIC control devices, newest ferrite cores and multi-layer capacitors, engineers at TDK-Lambda have reduced the component count significantly, providing in a single-board solution with a low height of only 0.52-inch (13.2 mm) the same output power formerly only available on two-board designs. Further, the optimized reduced component count layout and high power density of the iQL/iQG Series provides a more reliable and very cost effective solution.
The fully regulated iQL Series are ideal for powering distributed, intermediate and Advanced Telecom Computing Architecture (ATCA) bus applications. For conventional power rails, the 'standard' output voltages of 2.5V, 3.3V and 5V are equipped with both remote sense and output trim (-20/+10%), suitable for powering a wide array of devices. The 8.3V and 12V output models feature output trim (+20/-10%) without remote sense.  This family also boasts wide input voltage ranges of either 18-36V or 36-75V. Output power ratings range from 150W to 300W depending upon the output voltage.
The iQG Series is available with a nominal 12V at 25A output, providing up to 300-watts of continuous output power. They can operate from a wide range input of 36-75VDC and are ideal for distributed and intermediate bus applications that have limited airflow available for cooling.
The iQL/iQG is fully isolated from the input to output and input to baseplate (1500VDC). Standard features include fixed frequency operation, remote on/off, monotonic and pre-bias load start up, auto-recovery from input under-voltage, plus over-current, over-voltage and over-temperature protection circuitry. 
These converters are approved to a wide range of national and international safety standards, including UL60950 (US & Canada), VDE 0805 and CB scheme (IEC950) and are RoHS compliant. In addition they carry the CE Mark (EN60950) and come with TDK-Lambda's 3-year warranty.

The iQL and iQG series are available now and priced from $58.00each in 500-unit quantities. More information can be found at TDK-Lambda's web site

Fast Turn-Around High-Density Lead Frames for Complicated or Intricate Applications

Photofabrication Engineering (PEI) is offering a complete line of photochemically-etched surface-mount and insert-mount lead frames for integrated circuit manufacturing.  These lead frames are used in a wide variety of applications including semiconductors, glass-to-metal seals, and relays, and are also used in medical applications such as hearing aids.

Using base materials such as kovar, nickel-iron alloys, copper alloys, and pure nickel, PEI can plate lead frames in their entirety or selectively.  Lead-free plating materials include silver, nickel, gold, or tin, depending on the customer’s specific electrical and thermal conductivity requirements.  Since the lead frame is the main conduit by which heat flows from the chip to the printed circuit board, PEI tailors the manufacturing material to maximize the device’s operating life for any given application or environment.

PEI manufactures high-density lead frames with acute profiles and ultra-fine pitches, allowing for high pin counts.  Single- or double-sided lead frames can be etched without incurring the stresses associated with typical machining methods.  Most significant is the fact that PEI’s process can be used for lead frames that are too complicated or intricate for stamping.  Dimensions can be held to extremely tight tolerances, with no burrs or other surface irregularities. 

PEI’s lead frames range in thickness from 0.5 mil [0.0127 mm] to 40 mil [1.575 mm], with features as small as 4 mil [0.10 mm] on 0.010 in. [0.254 mm) centers, creating lead frames that are strong enough to be handled yet flexible enough to allow bending when necessary.  

A significant advantage of photochemical etching is the ability to reproduce large quantities of parts without tooling “wear,” so the millionth part is exactly the same as the first part.  Changes to tools can be implemented very quickly, and phototools are significantly less expensive than traditional tooling methods—ideal for manufacturing various parts or lead frames from prototype to production quantities.  Turnaround time using phototools is about 90% less than that for stamped frames.

New GORE® Filters Dramatically Improve Liquid Filtration Performance in Semiconductor Manufacturing

W. L. Gore & Associates (Gore)  has announced a major advancement in filtration technology with the release of GORE® Filters for Semiconductor Applications. This new family of 20nm- to 100nm-rated cartridge filters for chemicals, dilute chemicals, and ultrapure water in wet process tools incorporates a new high-flow ePTFE (expanded polytetrafluoroethylene) filtration media that allows a drop-in retention upgrade from 100nm to 30nm, enabling cleaner recirculation baths, reduced processing times and significant savings in cost of ownership.

The new cartridge filters, to be introduced at SEMICON West 2009, July 14-16 in San Francisco, enable up to three times the flow compared to the next best-in-class filters, with improved performance and no sacrifice in retention. GORE® filters provide a drop-in replacement that improves retention performance, reduces particle counts, lowers operating differential pressures, reduces processing times, and enables faster bath turnovers. The filters also allow flow rates to be maintained or even increased with as few as 1/3 the number of filters used previously. The result is a significant reduction in the capital costs typically associated with process upgrades.

3M and SUSS Announce Agreement on Temporary Wafer Bonding Technology to Enable 3-D Semiconductors

3M , and SUSS MicroTec, a leading supplier of semiconductor processing equipment, have announced an agreement to expand access to 3M Wafer Support System (WSS) equipment for temporary wafer bonding of ultrathin wafers required for 3-D packaging. As part of this non-exclusive agreement, SUSS MicroTec becomes an authorized equipment supplier for the 3M WSS and will manufacture and sell XBC300 and CBC300 wafer bonders configured to use 3M’s WSS materials including 3M Liquid UV-Curable Adhesive and Light-To-Heat Conversion coating. Under the agreement, both companies will work closely to address customer demands for high-performance process solutions that support high-volume manufacturing with a competitive cost of ownership.

3M WSS uses processes and materials for temporary wafer bonding to support wafer thinning and processing of ultra thin wafers for 3-D packaging. 3M’s innovative use of a UV-curable adhesive for wafer bonding to glass carriers provides robust wafer support throughout wafer grinding. This is particularly important in the multiple high-temperature cycles required in subsequent wafer processing steps. After processing, 3M’s unique Light-To-Heat Conversion layer allows low stress, room temperature debonding of the thinned wafer directly to the tape carrier. The thinned wafer is supported throughout the entire process reducing warpage, stress and process complexity compared to other processes that require high-temperature exposure and stress to the thinned wafer, or solvents to release the temporary bonding material. 3M’s WSS enables wafer processing currently in high-volume production at multiple semiconductor sites worldwide.

“SUSS MicroTec is a recognized leader in wafer bonding and applications for 3-D and MEMS markets. Working with an industry leader, like SUSS, allows 3M to focus on advanced materials development.
