摘要:
A thermal infrared-detector array has semiconductor-junction elements as detectors. It has high sensitivity and low noise and is fabricated in semiconductor-fabrication process. The semiconductor-junction elements are located in a monocrystalline silicon layer overlying a silicon-oxide layer on a monocrystalline silicon substrate. A signal-output circuit reading out signals from the detector elements includes transistors located on the monocrystalline silicon substrate.

A sensor element provided with a silicon substrate having a semiconductor circuit, a sensing-element portion formed on the silicon substrate and connected to the semiconductor circuit, and a cavity portion formed by removing a silicon substrate portion below the sensing-element portion, in which a removal resistance region having resistance against substrate removal is provided in the silicon substrate between the semiconductor circuit and the cavity portion.
摘要:
An infrared sensor includes a substrate, an insulator layer formed on the substrate, and a heat-sensitive semiconductor layer having a temperature dependent electrical resistance with a relatively large temperature coefficient of resistance. In order to improve sensitivity of the heat-sensitive semiconductor layer for detecting infrared rays, high concentration impurity semiconductor regions are positioned on either side of the semiconductor layer to form a semiconductor section. The high concentration impurity semiconductor sections have a higher absorption coefficient of infrared rays than the semiconductor layer. Thus, the semiconductor section itself both detects and absorbs infrared rays with or without providing any heat-absorbing layer. Further, electrodes are connected to each high-concentration impurity layer, which form an ohmic contact therewith.

An electronic device (200) includes a display (202) and an LC shutter (204), at least a portion of which is operatively positioned over the display (202). The LC shutter (204) provides switching between a transparent state and a diffusive state with high image integrity, and high transmission in the transparent state.

The LC shutter (204) includes a first dichroic polarizer (300), such as a broadband dichroic polarizer, a specular reflective polarizer (302), such as a broadband reflective polarizer, an LC cell (304), and a diffusive reflective polarizer (306). The LC cell (304) is interposed between the first dichroic polarizer (300) and the specular reflective polarizer (302). The diffusive reflective polarizer (306) is interposed between the LC cell (304) and the specular reflective polarizer (302). Related methods are also set forth.

Disclosed is an optical device comprising a polarizer package comprising an integrated combination of an absorbing layer and a compensator. Two of the identical polarizer packages can be crossed and used in a transmissive optical device. This polarizer package can also be used in combination with a reflective plate and a quarter wave plate in a reflective optical device. Such polarizer packages exhibit an improved viewing angle characteristic across all wavelengths of interest, has a large tolerance for compensators to be aligned relative to their preferred directions, and can be used within an LCD or emissive display system.
