METHOD OF ENCAPSULATING A SUBSTRATE

摘要

A method (200) of encapsulating a substrate (202) is disclosed, in which the substrate has at least the following layers: a CMOS device layer (204), a layer of first semiconductor material (206) different to silicon, and a layer of second semiconductor material (208), the layer of first semiconductor material arranged intermediate the CMOS device layer and the layer of second semiconductor material. The method comprises: (i) circumferentially removing (252) a portion of the substrate at the edges; and (ii) depositing (254) a dielectric material on the substrate to replace the portion removed at step (i) for encapsulating at least the CMOS device layer and the layer of first semiconductor material. A related substrate is also disclosed.
