摘要:
Low temperature wafer bonding process enhancement makes a wafer surface hydrophobic, preparing it with a buffered oxide etchant and then exposing it to H.sub.2 O.sub.2 before thermoelectric bonding. Has particular application to diaphragm-based pressure sensor construction.

摘要:
The formation of diaphragms by silicon wafer bonding provides for a structure having at least two such diaphragms with cavities in the wafers to which the diaphragm layer is bonded. Passageways through the wafers provide for communication of a fluid to the diaphragms. In some locations less than all of a plurality of diaphragms may be bonded to only one wafter having a cavity adjacent the diaphragm.
摘要:
This patent relates to the fabrication of diaphragm-based microstructures used primarily for sensing physical phenomena by detecting a change in deflection, resonance, or curvature of the diaphragm. The methods of fabrication described and claimed herein relate primarily to diaphragm-based diaphragms made of silicon, either single crystal or polycrystalline in form, although other materials may be used.
