ABSTRACT:
A dielectric buried layer is formed inside substrates which are directly bonded together. Firstly, a groove or a recess, or both are formed on the principal bonding plane of one of at least two kinds of semiconductor substrates to be bonded together. Once the semiconductor substrates are bonded together, the groove and recess form a space, which is filled with dielectric. Before forming the dielectric buried layer, the invention carries out a process of removing potential damage from corners of the groove and/or recess.
