Abstract

A semiconductor chip has a substrate that is in the form of a parallelepiped whose side surfaces are shaped as tilted parallelograms. Such a semiconductor chip has a high output efficiency and a homogeneous thermal load due to having at least two side surfaces that are provided with an acute angle and are in the form of parallelograms.
