Fabrication of electronic components using a noble support for front end fabrication and a less costly support, with specific desired physical properties, for back end fabrication

摘要

Fabrication of electronic components comprises: (a) selecting a noble support substrate of which the physical and chemical properties are appropriate for the fabrication of the electronic components; (b) effecting, at the level of an active layer (3) supported by the substrate and/or constituting a part of it, all the stages, non-contaminating or non-destructive for the substrate, of formation of semi-finished electronic components (6); (c) transferring the active layer supporting the semi-finished electronic components on to a reception substrate (8) or onto a stiffener (7) for effecting the polluting finishing stages of the electronic components.
