Status and trends in 300mm manufacturing

摘要

Many observers were surprised by the initial "slow ramp" of 300mm manufacturing. The first 300mm fab was built by Siemens (before spinning out Infineon) and Motorola (before spinning out Freescale), and then two years passed before the second 300mm fab was operational. The surprising element of this was that anyone was surprised! After all, Intel built the first 150mm fab, and then there was a delay before the industry adopted the new wafer size.
