Researchers at Lucent Technologies Bell Laboratories say they have produced a single-chip microphone and RF circuit by using micro-machining techniques.
The chip has a 100 micron base and includes an aluminium-nitride-on-silicon RF filter instead of a conventional microphone ceramic filter. The inductor and capacitor were made by micro-machining techniques.
The microphone on a chip has many potential applications in a wide range of consumer electronics devices and could be easily added to many current devices. It could also be used to produce a “Dick Tracy” style wristwatch sized wireless communications device. Bell Labs says it is using micro-machining to develop other types of products.

Micro-machining involves using chip based technologies to create tiny mechanical and electronic components.
