Abstract
PURPOSE: To enable the identification of the propriety of noise characteristic of an integrated circuit by forming electrode pads to be connected to the collector, base and emitter of an initial stage transistor of an amplifying system on a chip.
CONSTITUTION: Terminals connected to all electrode are formed on a semiconductor chip in such a manner that the terminals 6, 2, 7 are connected to the emitter, base, collector of one Q2 of differential transistors Q1, Q2 forming the initial stage circuit of an integrated amplifier. Since the HEF of the transistor Q2 of the initial stage circuit can be accordingly measured in a wafer state by the terminals 6, 2, 7, the propriety of the noise characteristic can be identified. Since the terminals 6, 7 are not necessary as the termianls for amplifying function, they are not necessary to be bonded via wires to external leads.
