A pressure sensor may include a first membrane that flexes in response to pressure, a reference cavity covered by the first membrane where the reference cavity contains a vacuum and a second membrane, adjacent to the first membrane, the first and second membranes forming a capacitor having a capacitance that varies in accordance with the flexing of the first membrane and the pressure.
摘要:
An electrical device includes a plurality of integrated circuits respectively fabricated in a first substrate bonded to a second substrate by a bond that deforms above, but not below, a deformation condition. The deformation condition can be a predetermined pressure from opposing surfaces on the first and second substrates or it can be a predetermined combination of temperature and pressure from opposing surfaces on the first and second substrates.

This invention provides a system and method for hermetically sealing a post media-filled package with a metal cap. The method can include the operation of filling a MEMS package through a fill port with at least one medium. A further operation can be plugging the fill port in the MEMS package with a sealant. Another operation can include depositing a metal cap over the sealant to hermetically seal the fill port.

A method for packaging and singulating a wafer having a plurality of micro devices includes providing a multi-lid substrate having a trench having intersection portions and non-intersection portions formed on a first side of the multi-lid substrate. The multi-lid substrate is coupled to the wafer such that the intersection portions of the trench pattern extend adjacent to at least three micro devices. Portions of the multi-lid substrate between a second side of the multi-lid substrate and the trench pattern are removed while the multi-lid substrate is coupled to the wafer.

A substrate for a fluid ejection device includes a first side, a second side opposite the first side, spaced etch stops extending into the substrate from the first side, and a fluidic channel communicating with the first side and the second side, wherein a first portion of the fluidic channel extends from the first side toward the second side between the spaced etch stops and a second portion of the fluidic channel extends from the second side toward the first side to the spaced etch stops.
摘要:
An inkjet print cartridge comprising a printhead that is formed using a sequence of etch process steps is described. The first etch of the two etch step process is comprised of a wet chemical etch. A dry etch process follows. Both etch steps are consecutively initiated from the back of the wafer. The fabrication process described offers several advantages including precise dimensional control of the ink feed channel, greater packing density of ink ejectors disposed in the printhead and greater printing speed. Additionally, the time required to manufacture the printhead, in contrast to a conventional printhead, is reduced.
