Abstract:
A method of forming a device is disclosed. The method includes providing a substrate and forming a device layer on the substrate having a formed thickness TFD. A capping layer is formed on the substrate having a formed thickness TFC. Forming the capping layer consumes a desired amount of the device layer to cause the thickness of the device layer to be about the target thickness TTD. The thickness of the capping layer is adjusted from TFC to about a target thickness TTC.
