Title: Characteristic measuring method for microwave element
Inventor: SAWAI TETSUO
IPC: G01R31/26
Filed: 1988-08-05
Abstract: PURPOSE:To measure accurate parasitic capacity even when the carrier density of a channel area is not constant by manufacturing and using plural microwave elements which differ in Schottky junction area. CONSTITUTION:Three kinds of Schottky barrier type (MES) FETs are manufactured which differ in Schottky junction area while, for example, the gate length of the MES FETs is constant and the gate width Wg is set to 200, 280, and 400mum. The S parameters of the three kinds of the MES FETs are found on a wafer by making gate biases constant. Then an equivalent circuit shown in a figure is assumed to optimize measured S parameters. Further, the results are used to find the parasitic capacity from the point (segment) where Wg=0 by plotting based upon the capacity on the longitudinal axis and gate width Wg on the lateral axis. Consequently, the parasitic capacity consisting of wire bonding pad capacity and the capacity generated between probes at the time of measurement is found at a specific frequency.
