Novel Composite Semiconductor Substrate for Thin-Film Device Transfer

Not limited by wafer crystallographic orientationNot limited to Si homoepitaxy (can be used on other semiconductor materials)Starting materials can be reused, saving upfront costs

Semiconductor and thin film device fabricationDevice substrate transferLow cost manufacturing of silicon based solar cells

Researchers at UCLA have identified a high quality composite semiconductor substrate for epitaxial deposition of electronic device layers also capable of transferring device layers from the composite substrate to another substrate of choice. This technique offers to reduce costs associated with having to replace starting materials and it can also be extended to a variety of semiconductor material combinations to create transfer-ready semiconductor substrates. This transfer substrate and process will be useful for any thin film semiconductor device manufacturers.

Background

Current state-of-the-art electronic device processing trends are increasingly moving towards thin film devices, flexible electronics, and sophisticated three-dimensional integration schemes, all of which require device layers to be transferred from a growth substrate of one desired property (e.g., a desired lattice parameter) to an alternate substrate with other desired qualities (e.g., mechanical flexibility).
