Debbie Forray and Ilya Furman, Henkel Corp., compare a self-filleting die attach paste to film-based adhesives.
Strong consumer demand for increased stored content on cell phones, MP3 players, and digital cameras continues to drive the memory market to higher production volumes. This is an intensely competitive marketplace that pushed selling prices lower in 2007 vs. 2006 and even lower still in late 2008 and early 2009.
In light of these market developments, semiconductor companies are seeking lower-cost die attach material solutions to replace the higher-cost, film-based adhesive materials used for certain applications. One such material is self-filleting die attach paste.
