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 5):
The MEMS silicon composite flow sensor of  claim 1  wherein the thermally isolated suspending membrane is deployed to provide enhanced sensitivity and fast response time for flow rate measurement; wherein the underneath cavity is formed by etching through silicon materials until reached to the silicon dioxide layer inside the silicon-on-insulator wafer; wherein the silicon dioxide layer is used as an etching stop layer.
