Abstract:
A method for forming an integrated circuit includes transforming at least a portion of a first substrate layer to form a conductive region within the first substrate layer. An integrated circuit device is provided proximate an outer surface of the first substrate layer. The integrated circuit device transmits or receives electrical signals through the conductive region. A second substrate layer is disposed proximate to the outer surface of the first substrate layer to enclose the integrated circuit device in a hermetic environment.

Abstract:
A method of manufacturing a semiconductor device includes providing a semiconductor substrate having first and second main surfaces opposite to each other. A trench is formed in the semiconductor substrate at the first main surface. The trench extends to a first depth position in the semiconductor substrate. The trench is lined with the dielectric material. The trench is filled with a conductive material. An electrical component is electrically connected to the conductive material exposed at the first main surface. A cap is mounted to the first main surface. The cap encloses the electrical component and the electrical connection.
Abstract:
A method for forming through substrate vias (TSVs) in a non-conducting, glass substrate is disclosed. The method involves patterning a silicon template substrate with a plurality of lands and spaces, bonding a slab or wafer of glass to the template substrate, and melting the glass so that it flows into the spaces formed in the template substrate. The template substrate may then be removed to leave a plurality of TSVs in the glass slab or wafer.
Abstract:
The invention relates to a micromechanical measuring element (1) which has a sensitive element (21) and a support (3). The sensitive element (21) is connected to the support (3) by means of at least one first and at least one second solder connection (41, 42), said sensitive element (21) being electrically contacted via the first solder connection (41). Furthermore, the sensitive element (21), the support (3), and the second solder connection (42) form a first chamber (51) which has a first opening (61). The invention further relates to a method for producing a micromechanical measuring element (1).

Abstract:
This disclosure provides systems, methods and apparatus for glass packaging of integrated circuit (IC) and electromechanical systems (EMS) devices. In one aspect, a glass package may include a glass substrate, a cover glass, one or more devices encapsulated between the glass substrate and the cover glass, and bond pads configured to attach to a flexible connector and in electrical communication with an encapsulated device. In some implementations, a flexible connector may be used to electrically connect a device within the glass package to an electrical component, such as an integrated circuit (IC) device or PCB, outside the glass package.
