Claim:
1. A semiconductor device, comprising: a first dopant injection layer formed by sintering first particles is arranged at a first location of a semiconductor layer or substrate composed of a semiconductor element; wherein the first particles are essentially composed of the same semiconductor element as the semiconductor layer or substrate and are doped with a p-type or n-type dopant; wherein the first dopant injection layer is coalesced with the semiconductor layer or substrate; wherein the crystal orientation of the first dopant injection layer is the same as the crystal orientation of the semiconductor layer or substrate; wherein an electrode is formed on the dopant injection layer; and wherein a dopant concentration at a depth of 0.1 μm from a surface of the first dopant injection layer is 1×10
