Self-aligned metal/IDP (SMI) technology is proposed to achieve high-speed bipolar transistors. SMI technology produces stacked metal/in-situ doped poly-Si (IDP) base electrodes that have a small thermal budget to obtain low base resistance and a shallow link base for small-collector capacitance and high-cutoff frequency. A 16.2-ps delay time in an ECL ring oscillator, and a delay time of 14.3 ps in a differential ECL ring oscillator were achieved by using SMI technology with an ion-implanted base.
