Reflecting On The SPIE Advanced Lithography + Patterning Symposium 2025


The mood at this year’s SPIE Advanced Lithography + Patterning Symposium was decidedly upbeat. The outlook for business is good, due in large measure to expectations of high demand for chips, driven by artificial intelligence (AI). To realize the potential of AI, increases in chip performance and efficiency are needed, which, in turn, requires advanced patterning. In the Symposium’s technic... » read more

Four Things Every Engineer Should Know About PFAS


What are PFAS chemicals? “PFAS” is an acronym for per- and polyfluoroalkyl substances. These man-made chemicals migrate into soil, water, and air when produced and used. There are many ways humans come in contact with PFAS, such as in non-stick cookware or cosmetics, but by far the most significant impact on human health is when PFAS is consumed in drinking water. Exposure to PFAS may resu... » read more

Review of essential use of fluorochemicals in lithographic patterning and semiconductor processing


New academic paper by researchers from Cornell University.   Abstract "We identify and describe categories of fluorochemicals used to produce advanced semiconductors within the lithographic patterning manufacturing processes. Topics discussed include the per- and polyfluoroalkyl substance (PFAS) materials used and their necessary attributes for successful semiconductor manufacturing... » read more
