It could cost about $12 billion in R&D investments for 450-mm, Muse said. ''The move to 300-mm was very much more expensive than the prior wafer transitions. While estimates from VLSI/Sematech suggest the 125-mm transition cost only ~$250-300 million and the 150-mm transition ~$700 million, the 300mm cost ~$12 billion,’’ he said.
''It is assumed that the 450-mm transition will not be cheap, and clearly equipment companies are reluctant to pay the full tab. We will likely see a chicken and egg game, but we do expect chipmakers to help support the tool development efforts with equipment companies, at the same time, sharing some of the higher dollars received in the current golden era of capital intensity,’’ he said.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
