Abstract
An FOM (figure of merit) enabling evaluation from a cost aspect, as well as evaluation of electrical performance, is newly proposed to provide a method of manufacturing based on the FOM a semiconductor chip intended for a lower cost production in addition to satisfying electrical performance. An FOMof a semiconductor chip is defined as the product of a term represented by electrical performance of a substrate S and a term represented by a semiconductor chip cost C; the FOMof each of the semiconductor chips on substrates S, Sof different type is determined by calculation of the product thereof. Based on the magnitudes of the calculation results, a desired substrate is selected from the substrates S, Sand then a semiconductor chip is fabricated by forming a semiconductor element on the desired substrate selected.
