摘要:
A method of forming an inertial sensor provides 1) a device wafer with a two-dimensional array of inertial sensors and 2) a second wafer, and deposits an alloy of aluminum/germanium onto one or both of the wafers. The alloy is deposited and patterned to form a plurality of closed loops. The method then aligns the device wafer and the second wafer, and then positions the alloy between the wafers. Next, the method melts the alloy, and then solidifies the alloy to form a plurality of conductive hermetic seal rings about the plurality of the inertial sensors. The seal rings bond the device wafer to the second wafer. Finally, the method dices the wafers to form a plurality of individual, hermetically sealed inertial sensors.
摘要:
A method of producing a MEMS device provides a first substrate having a first interior surface and thickness, and a second substrate having a second interior surface. The method also forms at least one closed wall on at least one of the first and second substrates, weakens the first substrate in a plane generally parallel to the first interior surface, and secures the first substrate to the second substrate. The at least one closed wall extends between the first interior surface and the second interior surface. The method further separates a portion of the first substrate along the plane generally parallel to the first interior surface after securing the first and second substrates, and removes an excess portion of the first substrate to produce a reduced thickness first substrate of no greater than about 20 microns.

A method for play of a parlor entertainment unit including a remote activation assembly and an activation-sensing unit. The activation-sensing unit, which may be battery operated and housed in the entertainment unit, may be in an energy-conserving sleep mode until the activation-sensing unit receives a wake-up signal. In one embodiment, the wake-up signal may be generated by the engagement of an activation mechanism, such as a coin slide. After being awoken, the activation-sensing unit may transmit an inquiry to the remote activation assembly as to whether the associated entertainment unit has been selected for play and/or whether there is a sufficient number of credits available for play. If that entertainment unit has not been selected for play, the activation-sensing unit may return to a sleep mode. However, if sufficient play credits are available for the entertainment unit, play may commence.

A low-temperature inorganic dielectric ALD film (e.g., Al2O3 and TiO2) is deposited on a packaged or unpackaged chip device so as to coat the device including any exposed electrical contacts. Such a low-temperature ALD film generally can be deposited without damaging the packaged chip device. The ALD film is typically deposited at a sufficient thickness to provide desired qualities (e.g., hermeticity for the entire packaged chip device, passivation for the electrical contacts, biocompatibility, etc.) but still allow for electrical connections to be made to the electrical contacts (e.g., by soldering or otherwise) directly through the ALD film without having to expose the electrical contacts.

摘要:
A sensor element is capped by bonding or otherwise forming a cap on a sensor element. The sensor may be hermetically sealed by using a hermetic cap and hermetic bonding material or by applying a hermetic coating. The sensor may be filled with a gas at an elevated pressure. The sensor may alternatively or additionally be filled with a special gas, such as a gas having a density-to-viscosity ratio above approximately 0.2.
