SEMICONDUCTOR ELEMENT AND METHOD FOR MANUFACTURING SAME

摘要

Provided is a semiconductor element which can suppress deterioration of element characteristics even when a semiconductor element section includes a plurality of directions having different thermal expansion coefficients within an in-plane direction. A semiconductor laser element (the semiconductor element) is provided with the semiconductor element section, which includes a direction of [1-100] and a direction of [0001] having different thermal expansion coefficients within the in-plane direction of a main surface, and a sub-mount, which includes an arrow (E) direction and an arrow (F) direction having different thermal expansion coefficients within the in-plane direction of the main surface. The semiconductor element section is bonded on the sub-mount so that the direction [1-100] of the semiconductor element section is close to the side of the arrow (E) direction than the arrow (F) direction of the sub-mount.
