【Abstract】 The 2-μm high performance single polysilicon bipolar device and its technology arereported in the paper.To improve the device performance,experiments were conducted on themodification and perfection of the basic processes,such as minimizing epitaxial auto-doping and de-fects,improving emitter-collector leakage and reducing emitter serial resistance. Typical processand device parameters are given.Using this technology,a gate delay of 250～500ps has been ob-tained for ECL ring oscillators,some even up to 200ps.更多还原
