    He's Yoshio Masubuchi from Toshiba... (Jim Kahle of IBM holding the wafer, the right is Masakazu Suzuoki of SCEI) Bad luck you didn't choose Suzuoki! :lol:

    The rows on the right have an odd number of chips.

    That's what i've come up with too.

    The photo resist is/was applied by dropping it on the center and spinning the wafer.
    <archairScientistMode="On">
    I don't think that applying foto resist is one of the more critical steps in the production chain.
    <archairScientistMode="Off">
    The silicon ingots are cylindrical due to the method used for growning them.

    90 nm 300mm wafer

    160 single core per wafer + strange logic or 80 double core per wafer + strange logic (no one think that it is edram ? ).. ..is a good yeld ?



    P4 wafer (300 mm?) 180 cores (130nm)

    the P4 at 180 nm was 217mm^2 (55Mtransistor) back in the 2001

    the P4 at 130 nm was 131mm^2 (55Mtransistor)


    G5 wafer (300 mm?) 175 cores (130nm)

    the G5 at 130 nm SOI was 118mm^2 (52Mtransistor)

    Power Efficient Processor Architecture and The Cell Processor

    PDF and slides
    it's a very good read, it shows how they went down to the high-frequency, single threaded, software driven (in order, branch and dma hints) route with their SPE design.

    EDIT: are there any chances to have ISSCC papers? :)

    The papers you are searching for, have not been published yet in electronic form and in the first 2 volume of isscc 2005 there no sign about what you are interested in, maybe in march will see something happen.

    Forgive my ignorance, but what's with the dual XDRRAM blocks for each CELL? What's the significance of that?
