A method of forming an opening in an insulating layer covering a semiconductor region including germanium, successively including: the forming of a first masking layer on the insulating layer; the forming on the first masking layer of a second masking layer including an opening; the etching of an opening in the first masking layer, in line with the opening of the second masking layer; the removal of the second masking layer by oxygen-based etching; and the forming of the opening of said insulating layer in line with the opening of the first masking layer, by fluorine-based etching.

Contacting area on germanium

A method of forming an area of electric contact with a semiconductor region mainly made of germanium, comprising the forming of a first area made of a first intermetallic material where more than 70% of the non-metal atoms are silicon atoms. There is also described a device including such a contacting area.

The present disclosure relates to a method of manufacturing a semiconductor device, including the successive steps of: a) forming doped germanium on a germanium layer covering a first support; b) covering said doped germanium with a second support; and c) removing the first support.

Manufacturing of a semiconductor photosensitive device

A nanoelectronic system comprised of n microelectromechanical or nanoelectromechanical devices arranged on a connection support to electrically connect the n devices, each device with an interaction area, at least one mechanical anchor and a first terminal, a second terminal and a third terminal, the relative arrangement of the first, second and third terminals, the anchor area and the interaction area being identical or similar for the n sensors, the first terminal of each device being intended to recover a signal emitted by each representative device of the interaction area state. At least part of the devices are arranged in such a way that the geometric location of the first terminal of one of the adjacent devices is identical to the geometric location of the first terminal of said other adjacent device, the first terminals being coincident.
