Anodic bonding method and electronic device having anodic bonding structure

InactiveUS7153758B2Good close adhesionBond be not deteriorateLamination ancillary operationsLaminationAnodic bondingElectrical conductor
In anodic bonding between a conductor or semiconductor and glass, in order to attain good adhesion at a lower bonding temperature than usual and improve the toughness at its boundary to obtain higher reliability for a bonded portion even in a case where bonded members are warped or dust is present at the bonding boundary, a soft metal film is formed on the surface of a conductor or semiconductor on which an active metal film having high reactivity with oxygen is formed, whereby a warp or dust, if any, can be absorbed by the deformation of the soft metal film, thereby to improve the adhesion at the boundary. Adhesion at the bonding boundary is improved even at a low bonding temperature of, e.g., about 200° C. Further, the toughness at the bonding boundary can be improved to increase reliability by roughening the bonded surface on the side of the glass.

Underwater acoustic vector sensor using transverse-response free, shear mode, PMN-PT crystal

The present invention is directed to an acoustic vector sensor, also called particle velocity sensor. <111> direction poled, shear mode, relaxor single crystals are used as the sensing elements. In addition, these crystal plates are cut at a special orientation such that they provide zero or minimum responses in the transverse directions, but have a maximum piezoelectric response in sensing direction. The piezoelectric sensor contains a proof mass, a base, and an aforementioned relaxor crystal. Three of the sensors are mounted orthogonally with a rigid case, and they are designated to sense the acoustic particle velocity in three designated directions, say X, Y, and Z. To solve the adverse lateral constraint problem (also known as clamping effect) associated with the relaxor crystal; reduced bonding area between the proof mass and the relaxor crystal are introduced. This feature greatly reduced the percentage of the bonding area for the crystal; consequently the free-state piezoelectric properties of the relaxor crystals are preserved.

Silicon-silicon-bonding-based pressure sensor capable of isolating packaging stress

The invention discloses a silicon-silicon-bonding-based pressure sensor capable of isolating a packaging stress. The pressure sensor includes a chip layer and a support layer. A lug used for silicon-silicon bonding is etched on the surface of the support layer. Gaps exist between other areas of the support layer and the chip layer. The structure is capable of avoiding too much consideration of material selection (such as a packing substrate of low stress and an adhesive of low stress) so that high-efficiency thermal isolation is realized comparatively easily and larger shock can be resisted and thus the pressure sensor is wider in application occasions.
