Abstract:
The invention provides a method for forming a semiconductor component with a rough buried interface. The method includes providing a first semiconductor substrate having a first surface of roughness R1. The method further includes thermally oxidizing the first surface of the first semiconductor substrate to form an oxide layer defining an external oxide surface on the first semiconductor substrate and a buried oxide-semiconductor interface below the oxide surface, so that the buried oxide surface has a roughness R2 that is less than R1. The method also includes assembling the oxide surface of the first semiconductor substrate with a second substrate. The invention also provides a component formed according to the method of the invention.

Abstract:
The invention concerns a method wherein a useful layer (1) is initially connected by a sacrificial layer (2) to a layer (3) constituting a substrate. Prior to etching of the sacrificial layer (2), at least part of the surface (4, 5) of at least one of the layers in contact with the sacrificial layer (2) is doped. After etching of the sacrificial layer (2), the surface (4, 5) is superficially etched, so as to increase the roughness of its doped part. Prior to doping, a mask (9) is deposited on part of the useful layer (1) so as to delimit a doped region and a non-doped region of the surface (4, 5), one of the regions constituting a stop after the surface etching phase.
