Abstract: A method for fabricating an image sensor is provided to control the generation of dark current of an image sensor by increasing the potential barrier of a channel stop region and by blocking the inflow path of dark current. A pad oxide layer(21) and a pad nitride layer(22) are sequentially formed on a substrate(20). The pad nitride layer, the pad oxide layer and the substrate are partially etched to form a trench. A first ion implantation process using B or BF2 is performed to form a channel stop region(27) on the interface of the substrate exposed by the trench. The impurity ions implanted into the channel stop region are activated to perform a second ion implantation process so that the potential barrier of the channel stop region is increased. An RTP is performed to cure the defect generated in the second ion implantation process.

Filed: 2004-01-20
Abstract: A method of processing an information signal comprising: applying a signal modification process to an information signal resulting in a processed signal, said signal modification process being controlled by at least one control parameter; comparing the processed signal with the information signal to determine a measure of perceptual quality of the processed signal; and adjusting said at least one control parameter in response to the determined measure of perceptual quality.

IPC: G11C29/50
Filed: 2004-03-03
Abstract: A method and apparatus for testing a static random access memory (SRAM) array for the presence of weak defects. A 0/1 ratio is first written to the memory array (step 100), following which the bit lines BL and BLB are pre-charged and equalized to a threshold detection voltage (step 102). The threshold detection voltage is programmed according to the 0/1 ratio of cells, so as to take into account specific cell criterion and/or characteristics. Next, the word lines associated with all of the cells in the array are enabled substantially simultaneously (step 104), the bit lines are then shorted together (step 106), the word lines are disabled (step 108) and the bit lines are released (step 110). Following these steps, the contents of the SRAM array are read and compared against the original 0/1 ratio (step 112). 10 Any cells whose contents do not match the original 0/1 ratio (i.e. those whose contents have flipped) are marked or otherwise identified as "weak" (step 114).
