Abstract:
A semiconductor device containing at least one transistor and at least one heater resistor in a heater resistor area adjacent the at least one transistor on a semiconductor substrate, the device comprising:a silicon substrate containing contact openings for metal contacts to the at least one transistor; a barrier layer in the contact openings and in the heater resistor area providing a diffusion barrier/heater resistor layer, the barrier layer being selected from a group consisting of TaN, Ta/TaAl, TaN/TaAl, TiWN, TaAlN, TiN, Ta(Nx, Oy), WSi(Nx, Oy), TaSi, TaSiN, WSiN, and TaSi(Nx, Oy); and a conductive layer adjacent at least a portion of the barrier layer for providing connection between a power source and the at least one heater resistor and at least one transistor, wherein the semiconductor device is devoid of a patterned and etched barrier layer in the heater resistor area.
