AUTHOR WITHDREW 9-12/9-13-11 per Kishio-san: Wafer Level Process Compatible Underfilling Pre-Applied Film Adhesive for Flip Chip and 3D Package
Keywords: Non conductive film, Cu pillar, underfill
AUTHOR WITHDREW 9-12/9-13-11 per Kishio-san: Demanded features of 3D and fine pitch flip chip bonding adhesive is discussed and the developed material is introduced, which is wafer level process compatible uderfilling pre-applied adhesive film. Cu pillar with solder cap and Cu pad bonding which is going to be one the major fine pith bonding technologies was demonstrated using the film.
