摘要： A first resist film for EB exposure, a buffer film, and a second resist film for i-line exposure are applied sequentially onto a substrate. Thereafter, the second resist film and the buffer film are subjected to patterning for forming a first opening. Then, dry etching is performed with respect to the first resist film masked with the second resist film to transfer the pattern of the second resist film to the first resist film and thereby form a second opening in the first resist film. Subsequently, a third resist film of chemically amplified type is applied to the entire surface of the first resist film to form a mixing layer in conjunction with the first resist film. As a result, the wall faces of the second opening are covered with the mixing layer and the width of the second opening is thereby reduced.

摘要： On a GaAs substrate are provided a buffer layer comprising an Undope-GaAs layer, a first n-InGaAs layer having an In composition ratio of 0.2, a second n-InGaAs layer having an In composition ratio of 0.02, a contact layer comprising an N.sup.+ type GaAs layer, a gate electrode, a source electrode, and a drain electrode. The first n-InGaAs layer and the second n-InGaAs layer form active layers in which an operating current flows. The second n-InGaAs layer having excellent crystallinity is formed on the first n-InGaAs layer. Consequently, a field effect transistor which displays a super low distortion characteristic having IP2 of 67.2 dBm and IP3 of 35 dBm can be manufactured with good reproducibility.
