IBM has revealed that it is working on a new 32nm processor manufacturing technique which could make the production of chips more accessible to smaller companies, as well as yielding performance gains. The process works in a similar way to the high-k/metal gate technique that is currently used by both IBM and Intel for their 45nm chips, which replaces some of the silicon in transistors with more efficient materials to pack more components into a single chip. IBM’s new technique uses a modified version of this process known as high-k/gate-first to develop its 32nm chips, which works by focusing on the most advanced components first. Big Blue has already demonstrated a working example of the 32nm technology with prototype static RAM chips, and mass production is expected to begin during the second half of 2009.
