The micro gas pressure sensor designed in this thesis can be fabricated using an IC compatible process, and it is composed of a heating resistor, a sensitive element and a testing resistor.

With the extensive use of the HV IC, the design of HLV compatible integrated circuits have become more and more important.

Magnetic micro inductor is a new kind of on-chip device, which has a better characteristic, and is compatible with the standard CMOS IC fabrication technology.
