Abstract: A depressurizing device includes a valve base, a first valve, a flexible member, and a top cover. The valve base has a pressure chamber and an outgassing chamber. Top and bottom surfaces of the pressure chamber have an opening and a first valve port respectively. The first valve is located in the pressure chamber and covers the first valve port. The flexible member is disposed on the valve base and has a depressurizing valve and a first outgassing port, the depressurizing valve covers the opening, and the first outgassing port is communicated with the outgassing chamber. A first outgassing channel is at least formed on the flexible member and communicates the pressure chamber to the outside of the valve base. The top cover is disposed on the flexible member and has a first depressurizing port and a second outgassing port.

Abstract: A diaphragm pump includes a valve seat, a head cover covered on the valve seat, and a pair of valve plates. A surface of the valves seat is formed concavely with a first receiving trough with a first flow passage, and a second receiving trough with a second flow passage. One of the valve plates is disposed in the first receiving trough, and the other one is disposed in the second receiving trough. The first and second receiving troughs respectively have a geometric shape corresponding with that of the valve plate. The valve plate has a sealing part, and at least one extending arm extended outwardly from the sealing part. The sealing part has a geometric shape being bilaterally symmetrical. The extending arm has an arced end. A gap is existed between an edge of the valves plate and the first receiving trough or the second receiving trough.

Abstract: A method includes receiving a device having a first layer and a second layer over the first layer, the first layer having a first overlay mark. The method further includes forming a first resist pattern over the second layer, the first resist pattern having a second overlay mark. The method further includes performing a first overlay measurement using the second overlay mark in the first resist pattern and the first overlay mark; and performing one or more first manufacturing processes, thereby transferring the second overlay mark into the second layer and removing the first resist pattern. The method further includes performing one or more second manufacturing processes that include forming a third layer over the second layer. After the performing of the one or more second manufacturing processes, the method includes performing a second overlay measurement using the second overlay mark in the second layer and the first overlay mark.
