Abstract:
A cell that is individually addressable by a first addressing line and a second addressing line, the cell comprising,a substrate for supporting the cell, a polysilicon layer disposed on the substrate, the polysilicon layer for forming a resistor, the polysilicon layer for forming a diode, the polysilicon layer for connecting together the resistor and the diode, the polysilicon layer for connecting the first addressing line to the resistor, a first insulating layer disposed on the polysilicon layer for insulating the polysilicon layer, the first insulating layer comprising a feed through extending to the polysilicon layer, a conducting layer disposed on the first insulating layer and connected to the polysilicon layer through the feed through for connecting the second addressing line to the diode, a fuel layer comprising combustible fuel in proximity to the resistor, the resistor being heated when conducting current when an ignition voltage is applied across the first and second addressing line so as to address the cell and ignite the combustible fuel, the fuel layer is a thin film fuel layer, the resistor and diode serving to ignite the combustible fuel when heated by conducting current through the first and second addressing lines, and a second insulating layer disposed between the fuel layer and the conducting layer.
