摘要： A system for programming integrated circuit (IC) dies formed on a wafer includes an optical transmitter that outputs a digital test program as an optical signal. At least one optical sensor (e.g., photodiode) is formed with the IC dies on the wafer. The optical sensor detects and receives the optical signal. A processor formed on the wafer converts the optical signal to the digital test program and the digital test program is stored in memory on the wafer in association with one of the IC dies. The optical transmitter does not physically contact the dies, but can flood an entire surface of the wafer with the optical signal so that all of the IC dies are concurrently programmed with the digital test program.

摘要： A MEMS device includes a first substrate structure and a second substrate structure. The first substrate structure has a conductive microstructure and an oxide material surrounding lateral side of the conductive microstructure. A thickness of the conductive microstructure and a thickness of the oxide material are approximately equivalent. The second substrate structure has an active region of the MEMS device, and the second substrate structure is coupled in spaced apart relationship with the first substrate structure to produce a cavity between the structures. The active region of the MEMS device is suspended above the cavity and the conductive microstructure underlies the cavity. The conductive microstructure is formed from a polysilicon structure layer and a local oxidation of silicon process is implemented to thermally grow the oxide material using the polysilicon of the structural layer. The second substrate structure may be coupled to the first substrate structure by fusion bonding.

摘要： An electric field sensor includes sense and reference cells. The sense cell produces a resistance that varies relative to an intensity of an electric field, and the reference cell produces a resistance that is invariable relative to the intensity of the electric field. An output signal indicative of the intensity of the electric field is determined using the difference between the resistances. A system includes an electric field source that outputs a digital test program as an electric field signal. The system further includes the electric field sensor formed with IC dies on a wafer. The electric field sensor receives the electric field signal. The received electric field signal is converted to the test program, and the test program is stored in memory on the wafer. The electric field source does not physically contact the dies, but can flood an entire surface of the wafer with the electric field signal.

摘要： A through substrate via (TSV) and method of forming the same are provided. The method of making the TSV may include etching a via opening into the backside of semiconductor substrate, the via opening exposing a surface of a metal landing structure. A conductive layer is deposited over the backside of semiconductor substrate, sidewalls of the via opening, and exposed surface of the metal landing structure. The conductive layer is coated with a polymer material, filling the via opening. The polymer material is developed to remove the polymer material from the backside of semiconductor substrate, leaving the via opening filled with undeveloped polymer material. A planar backside surface of semiconductor substrate is formed by removing the conductive layer.

摘要： In some embodiments a method of manufacturing a sensor system can comprise forming a first structure having a substrate layer and a first sensor that is positioned on a first side of the substrate layer, bonding a cap structure over the first sensor on the first side of the substrate layer, and depositing a first dielectric layer over the cap structure. After bonding the cap structure and depositing the first dielectric layer, a second sensor is fabricated on the first dielectric layer. The second sensor includes material that would be adversely affected at a temperature that is used to bond the cap structure to the first side of the substrate layer.

摘要： A system for programming magnetic field sensors formed on a wafer includes a magnetic field transmitter that outputs a digital test program as a magnetic signal. At least one digital magnetic sensor (e.g., magnetoresistive sensor) is formed with the magnetic field sensors on the wafer and is distinct from the magnetic field sensors. The digital magnetic sensor detects and receives the magnetic signal. A processor formed on the wafer converts the magnetic signal to the digital test program and the digital test program is stored in memory on the wafer in association with one of the magnetic field sensors. The magnetic field transmitter does not physically contact the wafer, but can flood an entire surface of the wafer with the magnetic signal so that all of the magnetic field sensors are concurrently programmed with the digital test program.
