摘要:
A Schottky barrier type compound semiconductor device includes an N type compound semiconductor substrate, an insulation layer having a penetrating hole through which part of the substrate is exposed, and a layer of high melting metal formed through the penetrating hole to form a Schottky barrier with the substrate. The insulation layer includes a phosphosilicate glass layer containing phosphorus at a concentration of 1.times.10.sup.21 /cm.sup.3 or more and contacting the substrate.
