摘要

结合介电隔离技术、n型外延技术和传统的两能级金属化技术,研究了砷埋埋集电极、硼基和砷注入自对准触点(ISAC)发射极的全离子注入ECL RAM的制备技术。5级ECL环形振荡器在开关电流为1ma时可获得0.5 ns的典型门延迟时间,在开关电流为0.25 mA时可获得0.9 ns的典型门延迟时间。ECL版本的1k位RAM的地址访问时间为10ns,功耗为350mw。

High speed bipolar process with full ion implantation and self-aligned contact structure
Technology for the fabrication of fully ion implanted ECL RAM with arsenic buried collector, boron base and arsenic implanted self-aligned contact (ISAC) emitter is developed combined with dielectric isolation technology, N-type epitaxy and conventional two level metallization. Typical gate delay time tpdis obtained of 0.5 ns with a switching current of 1 mA and 0.9 ns with 0.25 mA from 5-stage ECL ring oscillators. Address access time of 10 ns and a power dissipation of 350 mW are obtained with 1k-bit RAM in ECL version.
