Abstract

PURPOSE:To avoid the deterioration in high frequency performance, by providing the second metal layer not reacted with the solder used for mounting chip on the source between electrodes, when the source electrode or drain electrode on chip is shortened wit the chip rear side by means of the first metallic layer. CONSTITUTION:After providing the source electrode 5, drain electrode 4 and gate electrode 5 on the surface of the N type semiconductor thin layer 2 formed on the semi-insulating substrate 1, the metal layer 7 of Pt not reacted with the solder such as AuGe, AuSi, and AuSn is coated on the electrode 3. The SiO2 layer 8 is formed on it and after pelletizing, the Au plating layer 6 is made on chip and the electrode 3 and the chip rear side are shortened by this. Thus, since no plating layer 6 is coated on the SiO2 layer 8, the reaction between the solder and Au stops here and no reaction advances on the electrode 3. Accordingly, the source current is excellently flowed via the layers 6 and 7 and no adverse effect on the performance can be made.
