Title: A light beam polarization converter that can convert an illumination source into a polarization light source
Inventor: LEE CHIH-KUNG
IPC: G02B26/00
Filed: 1999-12-03
Granted: 2001-08-01
Abstract: Disclosed is to provide a light beam polarization converter that can converter non-polarized light beam into a single polarization light source, and is useful in electro-optical system such as liquid crystal displayer. The light beam polarization converter breaks the limitation of design and manufacture in the conventional light beam polarization converter. The incident light beam is focused and refracted in the bottom cover first, and pass through the gap without the high reflectivity phase retardation film between the said bottom cover and a substrate. Then, a polarization splitter film and a high reflectivity phase retardation film act on the incident light to produce a series of polarization splitting, reflection, total reflection and phase retardation and consequently a single polarized light outputs. The said bottom cover is used only to transfer the incident light into the substrate and the upper cover. The main optical behavior is occurred inside the substrate and the upper cover. The incident light is entering into the said substrate and the said upper cover, and the portion with the polarization coincidence with the said polarization splitter film in the interface of the said upper cover and the said substrate goes through the said polarization film, while the other portion with the opposite polarization state is reflected to the next polarization splitter film. The portion light with opposite polarization state is reflected again into the said high reflectivity phase retardation film, and produces the light polarization and said high reflectivity phase retardation film, and produces the light polarization and direction change. The changed polarization and direction portion light is reflected into the said polarization splitter film, and repeats the same optical processes of polarization splitting, reflection and phase retardation. Finally, there is a single polarization state light input. By using the interaction of light wave and optical films, the light beam polarization converter can converter the incident light into a single polarization state light without almost any loss of energy. Therefore, a non-polarized light beam can be converted into a single polarization light source in the way of high efficiency.

Title: Opimized floating P+ region photodiode for a CMOS image sensor
Inventor: ZHAO TIE-MIN
IPC: H01L27/146
Filed: 2000-11-08
Granted: 2002-01-01
Abstract: A photodiode with an optimized floating P+ region for a CMOS image sensor. The photodiode is constructed with a P+/Nwell/Psub structure. The Nwill/Psub junction of the photodiode acts as a deep junction photodiode which offers high sensitivity. The P+ floating region passivates the silicon surface to reduce dark currents. Unlike a traditional pinned photodiode structure, the P+ region in the present invention is not connected to the Pwell or Psub regions, thus making the P+ region floating. This avoids the addition of extra capacitance to the cell. The photodiode may be included as part of an active pixel sensor cell, the layout of which is fully compatible with the standard CMOS fabrication process. This type of active pixel sensor cell includes the photodiode, and may be configured with a three transistor configuration for reading out the photodiode signals. Examples of other configurations that the photodiode can be used with include two transistors, four transistors, log scale, as well as its ability to be used in a passive pixel implementation. Also, an additional optional N type layer can be introduced in between the P+ region and Nwell to fine tune the junction profile for special applications. In addition, the field oxide region may be made to extend over the photodiode, so as to reduce the exposure of the diode area to the field oxide region edge, which can be a source of dark current due to the high electric fields and mechanical stresses.

The adapter device can be connected to any socket of the power supply system (2), that is to say exactly where it is needed. Components for short-range radio links can be produced today in large numbers and very inexpensively. Due to the point-to-point connection, it is also possible to dispense with central control devices or call controllers.
