Reduction in Production pHEMT Process Variation Due to MBE Rotational Effects
Continuous azimuthal rotation is one method of
minimizing within run variation in MBE. In this work,
we present data showing the effects of rotation rate on
within run variation for production pHEMT wafers.
Also included is a basic model for calc More... |
