ABSTRACT:
A thin coating of carbon is used as a mask to define regions of a crystalline material of the group III-V compounds. A carbon mask is coated on portions of a surface of a substrate and the masked substrate contacted with the group III-V material to deposit the crystalline material only on the portions of the surface of the substrate not covered with the masking coating. The group III-V material will not be deposited on the carbon coating, since it is incapable of nucleating the growth of the crystalline material. Accordingly, a defined region of the crystalline material is formed. The carbon masking coating can also be used as a mask for etching cavities or recesses in a substrate of the group III-V material.
