Template:Use dmy dates Script error: No such module "Unsubst". Script error: No such module "Sidebar". The 3 μm process (3 micrometer process) is the level of MOSFET semiconductor process technology that was reached around 1977,[1][2] by companies such as Intel.
The 3 μm process refers to the minimum size that could be reliably produced. The smallest transistors and other circuit elements on a chip made with this process were around 3 micrometers wide.
Products featuring 3 μm manufacturing process
- Intel's 8085, 8086, 8088 CPU's launched in 1976, 1978, 1979, respectively, were manufactured using its 3.2 μm NMOS (HMOS) process.[1] Script error: No such module "Unsubst"..[3]Script error: No such module "Unsubst".
