Abstract : This invention discloses a method for improving field-effect transistors. Wherein the resistivity of the upper layer of the source-gate channel region of a GaAs field-effect transistor (FET) may be selectively raised. Impurity ions are implanted in the source-gate channel region followed by a much shallower implant of boron in the same region. The boron ion concentration should exceed the N+ impurity ion concentration by a factor of 2 or more.
