Title: An image sensor including photoelectric transducing - charge trap layer
Inventor: AHN SUNG MIN
IPC: H01L27/146
Filed: 2007-10-15
Abstract: An image sensor including photoelectric generating unit - charge trap layer is provided to increase quantum efficiency by improving a charge holding characteristic. A unit pixel(100) of the image sensor includes a substrate(110) having an active area, a gate insulating layer(120), a charge trapping layer(130), a blocking film(140), and a gate electrode(150). Source and drain regions(160a, 160b) are formed inside the substrate, and a gate insulating layer is formed by oxidizing the surface of the substrate. The gate insulating layer is formed between the charge trapping layer and the substrate while being used as an energy barrier. An electron-hole pair is generated according to the charge trapping layer, and a charge trapping layer performs a function such as the photoelectric transform of the image sensor. The charge trapping layer maintains the generated electron-hole pair, and a blocking film prevents the leakage of the gate electrode of the electron-hole pair. The gate electrode controls the formation of a channel at the substrate by polarizing the electron-hole pair while the image sensor is operated.

Title: Wireless terminal methods and apparatus for use in wireless communications systems supporting different size frequency bands
Inventor: LAROIA RAJIV
IPC: H04J11/00
Filed: 2005-10-12
Abstract: More efficient utilization of available bandwidth is implemented in an OFDM wireless communication system. The partitions of bandwidth may be of different sizes and may be different from the original system design parameters. Basic system structure such as the number of tones used and the number of OFDM symbol times in a slot is maintained throughout the system. Bandwidth is varied by adjusting the inter-tone spacing or bandwidth associated with a single tone. As the inter-tone spacing is increased, the OFDM symbol transmission time is decreased following an inverse proportional relationship. A wireless communications device, during a first period of time transmits signals using a first uplink frequency band of a first number of uniformly distributed tones and during a second period of time transmits signals using a second uplink frequency band of a second number of uniformly distributed tones, the second number being the same as the first number, the second frequency band being wider than the first frequency band.
