Mc. Ridgway et al., MEV IN-ION IMPLANTATION FOR ELECTRICAL ISOLATION OF P-INP(), Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 80-1, 1993, pp. 835-837
Electrical isolation of p+-InP by MeV In-ion implantation has been com
pared with a multiple low-energy, O-ion implant sequence. The large st
raggle associated with an MeV In-ion implant results in a disorder lev
el of comparable uniformity to that achieved with an O-ion implant seq
uence. The two implant schemes yield similar maximum sheet resistance
values (approximately 6 x 10(6) OMEGA/sq) and thermal stabilities (400
-degrees-C). However, the significant process simplification inherent
with a single In-ion implant is advantageous.
