  • Publication number: 20220359196
    Abstract: A method for manufacturing a semiconductor element includes providing, on a surface of a substrate 11, a mask 12 which has an opening 12a and in which a peripheral upper surface region of the opening is processed to have a predetermined structure, and epitaxially growing a semiconductor from the surface of the substrate exposed from the opening to the top of the peripheral upper surface region to fabricate a semiconductor element having a semiconductor layer 13 with the predetermined structure transferred thereon. In one example, the predetermined structure is due to a shape having a difference in level. In another example, the predetermined structure is due to a selectively arranged element, and the transferred element moves into the semiconductor layer.

Parameters indicating capturing position and capturing orientation of the two-dimensional image are obtained. A three-dimensional shape model representing a three-dimensional shape of the object is obtained. Two-dimensional geometrical features of the object are extracted from the two-dimensional image. Three-dimensional information with respect to a surface of the object close to each of the two-dimensional geometrical features is calculated from the three-dimensional shape model.
