Abstract:
The present invention disclosed a micromachined composite silicon flow sensor that is comprised of calorimetric flow sensing elements, time-of-flight sensing elements as well as independent temperature sensing element on a silicon-on-insulator device where the device layer is used for the thermal isolation membrane. The disclosed composite silicon flow sensor can measure mass flowrate, volumetric flowrate and flow medium temperature simultaneously, from which a full spectrum of flow parameters including flow pressure can be obtained. The sensor can be further used to alert any changes in physical properties of flow medium during operation. The disclosed manufacture process details the micromachining process of making such a sensor.

Claim (Index 6):
The MEMS silicon composite flow sensor of  claim 1  wherein the silicon composite flow sensor has its surface passivated with dielectric films with characteristic of good thermal conductivity, which is chosen from silicon nitride or silicon carbide with a thickness range of 100 nm to 500 nm.
