Abstract:
A method for forming a termination for a magnetic write head, the method comprising steps of:forming a magnetic write coil on a wafer, the write coil having an inner turn and an outer turn; forming a bottom capacitor plate for a capacitor on the wafer; forming a resistor on the wafer, the resistor having a first terminal and a second terminal; forming a dielectric layer over the bottom capacitor plate for the capacitor; forming a top capacitor plate on the dielectric layer; forming an overpass lead between the inner turn of the write coil and one of the bottom capacitor plate and the top capacitor plate; connecting the first terminal of the resistor to the capacitor plate that is not connected to the inner turn of the write coil, connecting the second terminal of the resistor to the outer turn of the write coil, an impedance formed by the write coil, the capacitor and the resistor substantially equaling a characteristic impedance Z0 of an interconnect circuit that will be connected to the write coil.
