Re: According to this, AMD's top .25u Athlon ran at 700MHz Here's what your hero had to say about .25 Athlon at 700mhz: Simply put, AMD has had to RAPIDLY develop new process technology and rush it into production just to TRY and remain competitive with Intel. This rushed-development has left no time for fine tuning, defect reduction, yield enhancement, etc. The new AthJOHN seems like a case in point. It appears to be made on a hybrid process using AMD's 0.18 micron front-end transistor process - to get the low operating voltage - but the back end is the 0.25 micron metallization process. Message 10942377 Followed by this post: I am assuming that AMD is using FRONT END PROCESSING from Raw Silicon up to the (first) Contact Mask taken from the 0.18 micron process (spacing excepted - see below) - using the various threshold adjusting implants and Vt's and gate oxide thickness and polysilicon gate linewidths developed for the 0.18 micron process. The SPACING of the transisitors (i.e., the density) conforms to the 0.25 micron design rules - as the BACK END Metallization/Contacts/Vias/and intermetal dielectrics are taken from the 0.25 micron process. siliconinvestor.com Which set up the peanut gallery to produce this post: The bad news: 1. The likely speed increase from the 0.18 micron back-end will be negligible at best. So if they are yielding 700's now they may get to 800Mhz but 1Ghz is a way away. 2. With copper they may well get some yield at 1Ghz. But unlikely with 0.18 Al. siliconinvestor.com The old Athlon shipped at 950mhz on Aluminum and 1.4GHZ on copper. Given that 1.3GHZ Durons are now shipping in aluminum, there may have been some additional headroom there.
