From MEMS to nano fabrication and nano sensors

【Abstract】

As origin of information in real world, high performance sensors are important not only to our human beings but also to smart robotics. Nano-structured materials have made it possible to form sensors at ultra-high performance. However, mass production at low cost is always desirable but not achieved in current time. In this talk, we will review our work of design and fabrication of nano structures in wafer level by MEMS technology, its integration with micro transducers and the corresponding high-performance nano sensors. With highly selective CMOS techniques, silicon nanowires (SiNWs) with narrow width (~20nm) were top-down fabricated on silicon-on-insulator (SOI) wafer, which is very useful to a simple, portable and rapid detection platform for bio/chemical detection. While, with the integration between micro-hotplate and nano-ordered sensing materials, gas sensor chips can be produced with high sensitivity, fast response time, and low power consumption. The proposed work represents a versatile approach for wide application of wafer-level fabricated sensors with high performance.

作为现实世界中的信息来源，高性能的传感器不仅对人类很重要，对智能机器人也很重要。纳米材料使制造超高性能的传感器成为可能。然而，低成本、大规模的传感器制造急需但远未实现。在本文中将综述我们通过MEMS技术在晶圆级设计和纳米制造方面的工作，以及实现微换能器和高性能纳米传感器的集成。利用高选择性的CMOS技术，在绝缘体上硅（SOI）晶片上我们采用自上而下的方法制造了小尺度（~20nm）的硅纳米线（SiNW），并进而实现了简单、便携、快速的生物/化学检测平台。同时，通过微热板和纳米有序传感材料的集成，生产出具有高灵敏度、快速响应时间和低功耗的气体传感器芯片。这些方法为未来高性能晶圆级纳米制造及纳米传感器的应用提供了一种通用方法。
