Abstract: A manufacturing method of a semiconductor structure includes the following steps. A first wafer is provided. The first wafer includes a first substrate and a first device layer. A second wafer is provided. The second wafer includes a second substrate and a second device layer. The second device layer is bonded to the first device layer. An edge trimming process is performed on the first wafer and the second wafer to expose a first upper surface of the first substrate and a second upper surface of the first substrate and to form a damaged region in the first substrate below the first upper surface and the second upper surface. The second upper surface is higher than the first upper surface. A first photoresist layer is formed. The first photoresist layer is located on the second wafer and the second upper surface and exposes the first upper surface and the damaged region. The damaged region is removed by using the first photoresist layer as a mask. The first photoresist layer is removed.

Abstract: An optical member driving mechanism for connecting an optical member is provided, including a fixed portion and a first adhesive member. The fixed portion includes a first member and a second member, wherein the first member is fixedly connected to the second member via the first adhesive member.

Abstract: An electronic ignition gun including a housing holding a gas lighter and a high voltage inductor, a press control switch pivoted to the housing and partially projecting out of an opening in the housing for operation with a hand to release the gas valve of the gas lighter and to trigger the high voltage inductor, the press control switch having a front projection adapted for triggering the high voltage inductor in inducing a high voltage for producing sparks for burning fuel gas, an arched rear side wall, and a bottom opening extended to a part of the arched rear side wall, and a gas lever balanced on a part of the gas lighter and having a notched coupling portion at one end coupled to the gas valve, an arched actuating face at an opposite end disposed in contact with the arched rear side wall of the press control switch, and a projecting block raised from one end of the arched actuating face and inserted into the bottom opening of the press control switch to guide the movement of the gas lever relative to the

Abstract: An electronic ignition apparatus including a housing, a gas well mounted in a gas well chamber inside the housing, a piezoelectric igniter mounted in a trough inside the housing and triggered to produce sparks at the front end of the housing, a metal nozzle the mounted in a front chamber on the housing and connected to the gas outlet valve of the gas well by a connecting tube and a flexible gas tube between the connecting tube and the metal nozzle tube, a push bar mounted inside the housing and moved to trigger the piezoelectric igniter, a link connected between the connecting tube and the push bar and moved by the push bar to lift the connecting tube from the gas outlet valve for permitting fuel gas to be drawn out of the gas well into the metal nozzle tube for burning by the sparks.

Abstract: An electronic igniter which includes a spring holder to hold a gas lighter inside the housing thereof on the bottom, a metal gas nozzle having a gas inlet connected to the gas outlet of the gas lighter and a nozzle tip inserted into a hole on a metal top cover thereof spaced from a tip on the metal top cover, a piezo electronic unit having one end connected to the tip of the metal top cover and an opposite end connected to metal gas nozzle, and a control lever having an angle rod on the top stopped above the piezo electronic unit, a presser rod on the bottom stopped above the gas lever of the gas lighter, and a knob on the middle extended out of the housing. Pressing the knob of the control lever causes the piezo electronic unit to produce sparks between the nozzle tip of the gas nozzle and the tip of the metal top cap in burning the flow of fuel gas ejected through the gas nozzle.
