Abstract
A thin (45 Å) nitride-capped poly-resistor is presented which is compatible with the self-aligned-contact process owing to the use of high-temperature RTP annealing just after nitride deposition without pattern definition. It has several advantages, including a simple structure and fabrication process, tight control of the high poly-resistance and better I-V linearity
