摘要： To eliminate variations in measurement of the chip characteristics an MMIC chip has a pad main portion having the same width as a main line at an end of the main line The main line is located on a GaAs substrate. Pad auxiliary islands are adjacent to the pad main portion on one or both sides. A grounding wiring layer is on at least one side of the pad main portion with the pad auxiliary island interposed in between. The pad main portion and the pad auxiliary portions secure a sufficient bonding area. The electrical characteristics are measured by bringing probes into contact with the pad main portion and the grounding wiring layer(s). The electrical characteristics of the MMIC chip can be evaluated without an increase in bonding pad capacitance.

摘要： Three or more MESFETs are fabricated side by side on a semiconductor chip. A transmission line substantially identical in width with an area within which the MESFETS are fabricated is formed in parallel with the row of MESFETs.
