Abstract:
A method of processing an engineered substrate structure includes providing an engineered substrate structure including a polycrystalline substrate and an engineered layer encapsulating the polycrystalline substrate, forming a sacrificial layer coupled to the engineered layer, joining a solid state device structure to the sacrificial layer, forming one or more channels in the solid state device structure by removing one or more portions of the solid state device structure to expose one or more portions of the sacrificial layer, flowing an etching chemical through the one or more channels to the one or more exposed portions of the sacrificial layer, and dissolving the sacrificial layer by interaction between the etching chemical and the sacrificial layer, thereby separating the engineered substrate structure from the solid state device structure.

Claim (Index 10):
The method of  claim 8  wherein the etching chemical comprises hydrofluoric acid (HF) or sulfuric acid (H 2 SO 4 ).
