Fabrication of GaAs devices with doped regions and devices so produced.

摘要

High carrier concentration, as well as abrupt change in such concentration in GaAs-based devices, is the consequence of selection of tin dopant-containing precursor compounds as used during layer growth. Alkyl tin compounds, as used during MetalOrganic Molecular Beam Epitaxy, are of particular value in the growth of pnp heterojunction bipolar transistors, likely in conjunction with other devices in large scale integrated circuits.
