Abstract
A method of manufacturing a substrate for a front-facing image sensor, comprises:—providing a donor substrate comprising a semiconductor layer to be transferred,—providing a semiconductor carrier substrate,—bonding the donor substrate to the carrier substrate, an electrically insulating layer being at the bonding interface,—transferring the semiconductor layer to the carrier substrate,—implanting gaseous ions in the carrier substrate via the transferred semiconductor layer and the electrically insulating layer, and—after the implantation, epitaxially growing an additional semiconductor layer on the transferred semiconductor layer.
