Abstract
The present disclosure relates to a semiconductor chip that allows electrical connections to be protected and a manufacturing method therefor. A semiconductor chip has a strip-shaped region including a plurality of recesses on a side surface thereof. The recesses are arranged in a matrix of rows and columns on the side surface of the semiconductor chip or in a zig-zag pattern in the region. At least two of the strip-shaped regions are formed. The strip-shaped regions are formed in different positions between the vicinity of the center and opposed ends of the side surface. The strip-shaped region is partly inclined. The present disclosure can be applied for example to a semiconductor chip for a semiconductor device in which connections for electrically connecting the semiconductor chip and the substrate are protected with underfill.
