发明名称 Method of and apparatus for protecting electronic circuit against radiation
摘要 An electronic circuit is protected against radiation when the threshold voltage of a semiconductor element included in the electronic circuit is shifted, in a positive direction, to a predetermined upper limit on the basis of the formation of a trap level at an interface within the semiconductor element, the number of trapped positive charges in the semiconductor element is controlled so that the threshold voltage is shifted, in a negative direction, to a value less than the predetermined upper limit.
