Abstract: The disclosure relates to a device for measuring an electrical characteristic of a substrate comprising a support made of a dielectric material having a bearing surface, the support comprising an electrical test structure having a contact surface flush with the bearing surface of the support, the bearing surface of the support and the contact surface of the electrical test structure being suitable for coming into close contact with a substrate. The measurement device also comprises at least one connection bump contact formed on another surface of the support and electrically linked to the electrical test structure. This disclosure also relates to a system for characterizing a substrate and a method for measuring a characteristic of a substrate employing the measurement device.

Abstract: The present disclosure relates to a process for the manufacture of a high resistivity semiconductor substrate, comprising the following stages: providing a first substrate with an in-depth weakened layer; providing a second substrate with a layer of an oxide at the surface; attaching the first substrate to the second substrate so as to form a compound substrate comprising a layer of buried oxide; and cleaving the compound substrate at the level of the weakened layer. The process additionally comprises at least one stage of stabilization, in particular, a stabilization heat treatment, of the second substrate with the layer of oxide before the stage of cleaving at the level of the weakened layer.
