摘要
Semiconductor structures and methods of forming semiconductor structures, and more particularly to structures and methods of forming SiGe and/or SiGeC buried layers for SOI/SiGe devices. An integrated structure includes discontinuous, buried layers having alternating Si and SiGe or SiGeC regions. The structure further includes isolation structures at an interface between the Si and SiGe or SiGeC regions to reduce defects between the alternating regions. Devices are associated with the Si and SiGe or SiGeC regions. The invention is also directed to a design structure on which a circuit resides.
