A method is provided for the integration of an optical gain material into a Complementary metal oxide semiconductor device, the method comprising the steps of: configuring a workpiece from a silicon wafer upon which is disposed an InP wafer bearing an epitaxy layer; mechanically removing the InP substrate; etching the InP remaining on epitaxy layer with hydrochloric acid; depositing at least one Oxide pad on revealed the epitaxy layer; using the Oxide pad as a mask during a first pattern etch removing the epitaxy to an N level; etching with a patterned inductively coupled plasma (ICP) technique; isolating the device on the substrate with additional pattern etching patterning contacts, applying the contacts. |
