按集成度高低分類

集成電路按集成度高低的不同可分為：

SSIC 小規(guī)模集成電路(Small Scale Integrated circuits)

MSIC 中規(guī)模集成電路(Medium Scale Integrated circuits)

LSIC 大規(guī)模集成電路(Large Scale Integrated circuits)

VLSIC 超大規(guī)模集成電路(Very Large Scale Integrated circuits)

ULSIC特大規(guī)模集成電路(Ultra Large Scale Integrated circuits)

GSIC 巨大規(guī)模集成電路也被稱作極大規(guī)模集成電路或超特大規(guī)模集成電路(Giga Scale Integration
