中国科学院微电子研究所成立于1958年，是中国微电子科学技术与集成电路领域的重要研发机构。 

微电子所前身为原中国科学院109厂。1986年，109厂与中国科学院半导体研究所、计算技术研究所有关研制大规模集成电路部分合并为中国科学院微电子中心。2003年9月，正式更名为中国科学院微电子研究所。 

微电子所在半导体器件与集成电路制造、集成电路设计与应用、集成电路装备等领域展开科研工作，设有13个研发单元，具备从原理器件、集成工艺、制造装备到核心芯片开发的全链条、体系化科技创新与关键核心技术攻关能力。 

微电子所是国务院学位委员会批准的博士、硕士学位授予权单位之一，是中国科学院大学集成电路学院主承办单位，现设有集成电路科学与工程、电子科学与技术、光学工程三个一级学科。

The Institute of Microelectronics of the Chinese Academy of Sciences, founded in 1958, is an important research and development institution in the field of microelectronics science, technology and integrated circuits in China.

Microelectronics Institute was formerly known as 109 Factory of the former Chinese Academy of Sciences. In 1986, the 109 Factory, the Institute of Semiconductors and the Institute of Computing Technology of the Chinese Academy of Sciences were merged into the Microelectronics Center of the Chinese Academy of Sciences. In September 2003, it was officially renamed Institute of Microelectronics, Chinese Academy of Sciences.

The Institute conducts scientific research in the fields of semiconductor devices and integrated circuit manufacturing, integrated circuit design and application, integrated circuit equipment and so on. With 13 research and development units, the Institute has the whole chain from principle devices, integration process, manufacturing equipment to core chip development, systematic scientific and technological innovation and key core technology research capabilities.

The Institute of Microelectronics is one of the institutions authorized by the Academic Degrees Committee of The State Council to award Doctor's and Master's degrees. It is the main organizer of the School of Integrated Circuits of the University of Chinese Academy of Sciences. It now has three first-level disciplines: Integrated Circuit Science and Engineering, Electronic Science and Technology, and Optical Engineering.
