Abstract:
A method for manufacturing a gas detector by a micro-electrical-mechanical systems (MEMS) process. The method includes providing a MEMS wafer including a plurality of mutually adjacent units; forming a gas sensing material layer on the MEMS wafer; bonding a structure reinforcing layer and the MEMS wafer through anode bonding; providing an adhesive tape; performing a cutting process to form a gas detection unit; and adhering the gas detection unit on a substrate by the adhesive tape to form a gas detector. The structure reinforcing layer is capable of enhancing the strength of a device and preventing edge collapsing, and hence enhancing the overall yield rate and reducing costs.

Claim (Index 4):
A method for manufacturing a multi-gas detector by a micro-electrical-mechanical systems (MEMS) process, comprising:\n P 1 : providing a MEMS wafer, the MEMS wafer comprising a plurality of mutually adjacent detection modules, each of the plurality of detection modules comprising a plurality of units, each of the plurality of units comprising a top portion, a side block portion extending from an edge of the top portion, and a bottom chamber formed by the top portion and the side block portion in a surrounding manner, the side block portions of the plurality of units mutually connected; P 2 : forming a gas sensing material layer on one side of the MEMS wafer opposing to the bottom chamber, the gas sensing material layer comprising a plurality of types of gas sensing materials respectively formed on the different units; P 3 : bonding a structure reinforcing layer with the MEMS wafer through anode bonding in a negative-pressure environment, wherein the structure reinforcing layer covers the bottom chambers, and is made of at least one selected from a group consisting of glass and borosilicate glass; P 4 : providing an adhesive tape on one side of the structure reinforcing layer opposing to the MEMS wafer; P 5 : performing a cutting process along connecting positions of the plurality of detection modules, and simultaneously on the structure reinforcing layer and the adhesive tape to form a plurality of multi-gas detection units; and P 6 : adhering one of the plurality of multi-gas detection units to a substrate by the adhesive tape to form a multi-gas detector.
