SEMICONDUCTOR DEVICE AND METHOD FOR MOUNTING SEMICONDUCTOR DEVICE

摘要

A semiconductor device is provided with a semi-annular device main body comprising an inner circumferential surface formed to have an arcuate shape in a planar view and an outer circumferential surface formed to have an arcuate shape in a planar view. A notched section into which a screw for fixing the device main body to a base section is inserted is formed in a first end surface on one end side and in a second end surface on the other end side in the circumferential direction of the device main body.
