tw, quick question, what's the difference between tapeout and 1st silicon? How much time between should we be seing between those 2 events? Tapeout is an antiquated term referring to the shipping of a tape containing the database for the mask set needed for fabrication. It's not done that way anymore but the name has stuck. The time from tapeout to 1st silicon varies depending on the priority assigned at the mask shop and the fab. A very rough estimate is 6-12 weeks. EP

Constantine, Re: "quick question, what's the difference between tapeout and 1st silicon? How much time between should we be seing between those 2 events?" I'm not Tim, but I believe I can answer that. Tape out can actually be defined a number of ways. In laymen's terms, it's the moment when they push the proverbial "red button" and get the process started for the first time on a new device or new device stepping. Realistically, though, there are many steps leading to tape out, and a company can easily count the beginning of tape out as any of those first steps. First silicon is when the manufacturing actually produces something on the other end. This might occur anywhere from 6-10 weeks after tape out, depending on the manufacturing process, the manufacturing prowess, and the speed at which it gets rushed through the fab, and all these are dependant on the company. wbmw
