Abstract

Process for neutralizing acceptor atoms in p-type InP. This process consists of subjecting to epitaxy a p-doped InP layer (4) and then a not intentionally doped Ga.sub.0.47 In.sub.0.53 As layer (6) on an InP semiinsulating substrate (2), followed by hydrogenating the InP layer exposing the assembly to a hydrogen plasma (8) with a power density below 0.07 W/cm.sup.2 at the most 250.degree. C.
