I just read the answer to this question asking how much a custom ASIC costs. It says that. When it comes to making an ASIC, the cost of the masks is HUGE. It is not uncommon at all for a set of masks (8 layers, 35 to 50 nm) to run US$1 Million! I'm curious why the cost is so huge. A photomask is an opaque plate with transparent areas that allow light to shine through in a defined pattern. Photomasks are commonly used in photolithography for the production of integrated circuits (ICs or "chips") to produce a pattern on a thin wafer of material (usually silicon). Several masks are used in turn, … Ver mais For IC production in the 1960s and early 1970s, an opaque rubylith film laminated onto a transparent mylar sheet was used.
