Abstract :
A "virtual" self-aligned, ion implantation process for fabricating IGFETs has been developed. N-channel IGFETs fabricated in semi-insulating InP substrates with this process show: (1) square-law characteristics, (2) an inverse-relationship between transconductance (g
m) and gate length (

), g
mċ

≈ 6 mS ċ µm, and (3) high surface channel electron mobilities on the order of 1000 cm
2/V.sec.
