  • Process for collective manufacturing of small volume high precision membranes and cavities
    Patent number: 7838393
    Abstract: The invention relates to a process for collective manufacturing of cavities and/or membranes (24), with a given thickness d, in a wafer said to be a semiconductor on insulator layer, comprising at least one semiconducting surface layer with a thickness d on an insulating layer, this insulating layer itself being supported on a substrate, this process comprising: etching of the semiconducting surface layer with thickness d, the insulating layer forming a stop layer, to form said cavities and/or membranes in the surface layer.
    Type: Grant
