Abstract:
1. A method for fabricating a slider having an integral spin valve transistor (SVT) disposed at an air-bearing surface (ABS) with a read-width (RW) and a stripe-height (SH), the SVT having an emitter, a collector and a base, the method comprising the unordered steps of: (a) preparing a polished semiconductor wafer surface; (b) forming a sensor stack having a top surface and including a first ferromagnetic (FM) layer in contact with and forming a Schottky barrier at the semiconductor wafer surface; (c) removing material from the sensor stack to form two sides defining the RW; (d) forming a FM shield layer over the milled sensor stack and in electrical contact with the top surface thereof; (e) forming a SVT emitter terminal, a SVT collector terminal and a SVT base terminal; and (f) polishing an edge of the semiconductor wafer to expose and define the ABS.
