Jakarta and MEMS Micromachining

Still on the subject of MEMS (Micro Electro Mechanical Systems), how is the fabrication technology different from conventional ICs (CMOS)?

The whole concept of MEMS is based on using IC technology to make micro mechanical systems but it turns out conventional IC technology is not enough. We need some additional processes.

One of the key enablers of MEMS is bulk micromachining, of which the Bosch process is most widely used.




Surface Micromachining is also widely used where we don’t need such deep structures.




Another widely used surface micromachining process is LIGA. This can be considered as an intermediate process between bulk and surface micromachining.



These three processes lie at the heart of most of the MEMS devices around us.
