| 术语 | complex bipolar |
| 释义 | complex bipolar 复合双极性(工艺,技术) A method used to produce memories significantly faster than standard transistor-transistor logic (TTL) or emitter-coupled logic (ECL). This involves an extra diffusion (to produce suchthings as small resistors, and low base and collector resistance in the transistors) and two layers of aluminum interconnection (to reduce interconnection resistance). These approaches produce extremely fast memories, but at considerably higher man ufacturing cost. 半导体集成电路工艺中制造高速存储器的一种方法,包括采用附加扩散以减少 电阻,使晶体管的基极、集电极的电阻减小;也包括采用双层铝连线以减少晶体管间的连线电 阻等。这样得到的存储器其运行速度比一般晶体管-晶体管逻辑(TTL)或射极耦合逻辑(ECL) 电路快得多,但制造成本却高得多。 |
