Title: Method of semiconductor characteristic evaluation
Inventor: NAGATSUMA KAZUYUKI
IPC: G01R31/26
Filed: 1990-01-26
Abstract: PURPOSE:To measure semiconductor characteristics simply and accurately by applying liquid metal to form electrodes on the upper (or lower) surface of n-type semiconductor and the lower (or upper) surface of p-type semiconductor. CONSTITUTION:A semiconductor is composed of layers having different doping concentrations. The semiconductor includes a surface layer of a first conductivity type 6 in which a p-n junction is formed by introducing an impurity of a second conductivity type. The n-type and p-type regions at the surface are brought into contact with liquid metals 1 and 2, respectively, to apply a voltage, so that voltage-current characteristics and voltage-capacitance characteristics may be measured to evaluate the quality and junction characteristics of the semiconductor. Since the evaluation is possible without complicated processes such as vacuum evaporation, accurate data is obtained in a short time.
