A phenomenon in which a bonding agent (56) that fixes an acoustic sensing element (32, 62, 72 to 82) to a base substrate (34) runs to through a back chamber (45) is prevented. A leakage of a back chamber (45) from a lower surface of the acoustic sensing element (32, 62, 72 to 82) is prevented. A deformation of the acoustic sensing element (32, 62, 72 to 82) is decreased to improve sensitivity of an acoustic sensor (31 , 61, 68, 71). A lower surface of the acoustic sensing element (32, 62, 72 to 82) is bonded to an upper surface of the base substrate (34) by the thermosetting bonding agent (56). In the acoustic sensing element (32, 62, 72 to 82), a vibration electrode plate (43) and a fixed electrode plate (44) that is opposite the vibration electrode plate (43) are prepared on an upper surface of an element substrate (41). The back chamber (45) is formed in the element substrate (41). The back chamber (45) is opened to the upper surface of the element substrate (41), and a lower surface of the back chamber (45) is closed into a pouched shape by the element substrate (41). The vibration electrode plate (43) is located in the upper surface opening of the back chamber (45), and an acoustic hole (55) is made in the fixed electrode plate (44) in order to pass an acoustic vibration.

Alternative methods of constructing a vertically offset structure are disclosed. An embodiment includes forming a flexible layer (12) having first and second end portions (13, 14), an intermediate portion (70) coupling the first and second portions, and upper and lower surfaces (48, 15). The distance between the upper and lower surfaces at the intermediate portion is less than the distance between the upper and lower surfaces at the first and second end portions. The first end portion is bonded to a base member (44). The second end portion of the flexible layer is deflected until the second end portion contacts the base member. The second end portion is bonded to the base member.
摘要:
A process to encapsulate electronic modules in a manner which is substantially resistant to water diffusion yet is carried out at moderate temperatures below 300° C., preferably below 150° C. is provided. The process forms a housing for electronic modules, in particular sensors, integrated circuits and optoelectronic components. The process includes the steps of: providing a substrate, of which at least a first substrate side is to be encapsulated; providing a vapor-deposition glass source; arranging the first substrate side in such a manner with respect to the vapor-deposition glass source that the first substrate side can be vapor-coated; and vapor-coating the first substrate side with a glass layer.
