摘要:
The present invention provides for the deposition of group III-V ternary epitaxial films onto the surfaces of suitable semiconductor substrates. The deposition is accomplished by a vapor phase epitaxy-hydride technique using a group III binary alloy as a group III metal source and phosphine, arsine or stibine as a group V hydride source.
摘要:
A process for depositing an epitaxial film of a III-V compound onto the surface of a crystallographically compatible substrate which includes contacting said substrate with a vaporous mixture of a group III element and a group V element to effect the deposition of a group III-V compound thereon while simultaneously introducing a flow of hydrogen halide gas during deposition of the group III-V compound.
摘要:
A method for depositing a (Hg,Cd)Te film onto a CdTe substrate by using two separate vaporizeable sources of reactant materials each maintained at separate and distinct temperatures followed by the step of mixing both of each sources with a hydrogen halide gas and passing the resulting mixtures over a CdTe substrate maintained at a lower temperature distinct and different from the temperatures maintained during vaporization of the two distinct vaporizeable sources.
