Abstract
A method for forming a termination for a magnetic write head in which a magnetic write coil having an inner turn and an outer turn is formed on a wafer. A bottom capacitor plate for a capacitor on the wafer. A resistor having a first terminal and a second terminal is also formed on the wafer. A dielectric layer is formed over the bottom capacitor plate for the capacitor. A top capacitor plate is formed on the dielectric layer. An overpass lead is formed between the inner turn of the coil and one of the bottom capacitor plate and the top capacitor plate. The first terminal of resistor is connected to the capacitor plate that is not connected to the inner turn of the write coil. The second terminal of the resistor is connected to the outer turn of the write coil. An impedance formed by the write coil, the capacitor and the resistor substantially equals a characteristic impedance Z of an interconnect circuit that will be connected to the write coil.
