Semiconductor growth method with thickness control
摘要:
Molecular beam epitaxy (202) with growing layer thickness and doping control (206) by feedback of sensor signals such as spectrosceopic ellipsometer signals based on a process model. Examples include III-V compound structures with multiple AlAs, InGaAs, and InAs layers as used in resonant tunneling diodes and hetrojunction bipolar transistors with doped and undoped GaAs layers, AlGaAs and InGaAs.
