A method is disclosed for fabricating a CPP read head for a magnetic disk drive having an electrical isolation layer. The method includes providing a first shield layer, depositing a sensor stack on the first shield layer, a CMP stop layer is deposited on the sensor stack, and a release layer is deposited a on the CMP stop layer. Photoresist material containing Si is deposited on the release layer, and the photoresist material is then patterned and then oxidized by Reactive Ion Etching to form a high temperature photomask. The electrical isolation layer is then deposited to surround the sensor stack using a high temperature deposition process. The read head is then continued as either an in-stack bias sensor with 'draped shield' variation, or a hard bias stabilization variation.
