摘要

In this paper we present a feasibility study of a PMOS compatible micromachmed flow sensor based on hot wire principle, developing a coupled thermal-electrical model and simulating its temperature profile and static characteristics. The transducer is a boron doped silicon heater resistor and the proposed process includes boron etch stop and bulk silicon micromachining techniques for achievement of the thermal isolation between the heater resistor and the silicon substrate. The main reason for developing a PMOS compatible sensor is to make it possible to fabricate a monolithic device, where the transducer and its signal conditioning and interface circuits are integrated in the same chip as a intelligent sensor.
