ABSTRACT:
The thin film transistor formed of polycrystalline silicon is positioned adjacent a heat reaction chamber. The gate electrode for the transistor is formed within a silicon substrate and a gate dielectric is positioned over the gate electrode. A pass transistor is coupled to the gate electrode, the pass transistor having a source/drain region in the same semiconductor substrate and positioned adjacent to the gate electrode of the thin film heating transistor. When the pass transistor is enabled, a voltage is applied to the gate electrode which causes the current to flow from the drain to the source of the thin film transistor. The current flow passes through a highly resistive region which generates heat that is transmitted to the heat reaction chamber.
