北京理工大学重庆微电子研究院（以下简称“重研院”）是由北京理工大学和重庆西永综合保税区管理委员会共同设立的单位，是北京理工大学直管的外派学术研发机构。
重研院依托北京理工大学现有科研及教学平台基础和能力，结合西永微电园的产业基础和发展规划，不断强化核心技术攻关克难，坚持推动产学研协同创新，紧密围绕成渝双城经济圈等国家战略部署，相应大学城、科学城小双城科技发展规划，努力建设国际化一流研究院。
重研院拥有一条覆盖MEMS工艺全流程的6英寸晶圆研发线，具备独立的MEMS芯片设计、制造、封装、测试能力，针对自研MEMS芯片开展面向市场的系统应用和量产产品开发，自研产品达到世界领先水平。
重研院主要从事微纳制造、MEMS智能传感芯片、集成电路设计、新型半导体材料、太赫兹技术以及轻量化智能感知微系统等方向的技术研发、人才培养以及产业孵化，产出成果可广泛应用于3D感知、无人驾驶、智能机器人、物联网、环境监测、精准医学等领域。
2021年，研究院获批重庆市博士后科研工作站。
BIT Chongqing Institute of Microelectronics and Microsystems, (hereinafter referred to as "The Institute") is an institution jointly established by Beijing Institute of Technology and Chongqing Xiyong Comprehensive Bonded Zone Management Committee. It is an non-local academic research and development institution directly managed by Beijing Institute of Technology.
Relying on the foundation and ability of the scientific research and teaching platform of Beijing Institute of Technology, and in combination with the industrial foundation and development plan of Xiyong Micro- Electric park, the Institute continues to strengthen the core technology research and overcome difficulties, adhere to promoting the collaborative innovation of industry, University and research, closely focus on the national strategic deployment such as the Chengdu Chongqing twin city economic circle, and work hard to build an international first-class research institute according to the scientific and technological development plan of the university town and the science town.
The Institute owns a 6-inch wafer R & D line covering the whole process of MEMS technology, with independent MEMS chip design, manufacturing, packaging and testing capabilities.
The Institute is mainly engaged in technology research and development, talent training and industrial incubation in the directions of micro-nano manufacturing, MEMS intelligent sensor chips, integrated circuit design, new semiconductor materials, terahertz technology and lightweight intelligent sensing micro systems. The outcome can be widely used in 3D sensing, driverless, intelligent robots, the Internet of things, environmental monitoring, precision medicine and other fields.
In 2021, the Research Institute was authorized to set up a Chongqing post-doctoral station.
