ABSTRACT:
The radiation resistance of an MOS transistor is improved by making the transistor in a manner such that, after the gate insulation layer is formed, all further steps are carried out at a relatively low temperature, i.e., less than about 900.degree. C. The source and drain regions are preferably formed by ion implantation with very little or no post implant thermal activation, and the metallization is applied by low temperature techniques.
