Wanted: Mask Equipment for Mature Nodes


Rising demand for chips at mature nodes is impacting the photomask supply chain, causing huge demand for trailing-edge masks and a shortfall of older mask equipment. The big issue is the equipment shortfall, which could impact customers on several fronts. Tool shortages could lead to longer mask turnaround times and delivery schedules for chips being developed at 90nm and above, which are bu... » read more

EUV Pellicle, Uptime And Resist Issues Continue


Extreme ultraviolet (EUV) lithography is moving closer to realization, but several problems involving scanner uptime, photoresists and pellicles need to be resolved before this long-overdue technology is put into full production. Intel, Samsung and TSMC are hoping to insert EUV into production at 7nm and/or 5nm. While the remaining issues don’t necessarily pre-empt using EUV, they do affec... » read more

Mask Maker Worries Grow


Leading-edge photomask makers face a multitude of challenges as they migrate from the 14nm node and beyond. Mask making is becoming more challenging and expensive at each node on at least two fronts. On one front, mask makers must continue to invest in the development of traditional optical masks at advanced nodes. On another front, several photomask vendors are preparing for the possible ra... » read more
