SEMICONDUCTOR DEVICE AND METHDO OF MANUACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device which is restrained from malfunctioning or increasing in a leakage current and a manufacturing method therefor. SOLUTION: A semiconductor device is equipped with a semiconductor substrate 1 provided with a primary surface, an element isolating region 10 provided on the primary surface of the substrate 1, an insulating layer 6 provided on the primary surface of the substrate 1, and a first semiconductor layer 11 provided in a prescribed region of the element isolating region 10 which is cut when a contact hole 13 is formed.
