Abstract :
The nonoverlapping super self-aligned structure (NOVA) is reported. Because of its nonoverlapping nature, this structure can be applied equally well to bipolar, CMOS, or BiCMOS processes. This structure effectively minimizes parasitic capacitance and resistance for both the MOS and bipolar devices. CMOS and bipolar devices are integrated into a high-performance BiCMOS technology. CMOS and emitter-coupled logic (ECL) ring oscillators with 1.5- mu m lithography are reported to have delays of 128 and 87 ps/stage, respectively.<>
