Abstract:
1. A strained Ge-on-insulator structure, comprising: a silicon substrate, wherein an oxide insulating layer is formed on a surface of the silicon substrate; a Ge layer formed on the oxide insulating layer, wherein a first passivation layer is directly formed on the oxide insulating layer, the Ge layer is directly formed on the first passivation layer, and the first passivation layer is a strontium germanide layer, a barium germanide layer, or a stannum germanide layer; a gate stack formed on the Ge layer, a channel region formed below the gate stack, and a source and a drain formed on sides of the channel region; and a plurality of shallow trench isolation structures extending into the silicon substrate and filled with an insulating dielectric material to produce a strain in the channel region.
