Title: CMOS image sensor capable of increasing punch-through voltage and charge integration of photodiode, and method for forming the same
Inventor: SHIM JIN-SEOP
IPC: H04N5/335
Filed: 2001-12-31
Granted: 2003-05-11
Abstract: A CMOS image sensor capable of increasing the punch-through voltage and the charge integration of a photodiode, and a method for forming the same. The punch-through voltage of a transfer transistor is increased, and the potential barrier is heightened between the photodiode and the floating diffusion region during the turn-off of the transfer transistor so as to increase the charge accumulation amount of the photodiode, while the photodiode is formed without resorting to a self-aligned ion-implantation. A p-type impurity region is formed under the gate electrode of the transfer transistor and within the semiconductor substrate, and the process can proceed without being limited by the self-alignment. Further, the p-type impurity region heightens the potential barrier between the photodiode and the floating diffusion region, i.e., the potential difference between the two regions is increased and, therefore, the charge accumulation amount is increased in the photodiode.

Title: Active matrix electroluminescent display devices, and their manufacture
Inventor: JASON RODERICK HECTOR
IPC: H01J1/62
Filed: 2003-03-20
Granted: 2008-01-01
Abstract: Physical barriers (210) are presented between neighbouring pixels (200) on a circuit substrate (100) of an active-matrix electroluminescent display device, particularly with LEDs (25) of organic semiconductor materials. The invention forms these barriers (210) with metal or other electrically-conductive material (240), that is insulated (40) from the LEDs but connected to the circuitry within the substrate (100). This conductive barrier material (240) backs-up or replaces at least a part of the drive supply line (140, 240) to which the LEDs are connected by a drive element T1. This transfers the problem of line resistance and associated voltage drop from within the circuit substrate (100), where it is severely constrained, to the much freer environment of the pixel barriers (210) on the substrate (100) where the conductive barrier material (240) can provide much lower resistance. Very large displays can be made with low voltage drops along this composite drive supply line (140, 240). Furthermore, the structure can be optimised to form a smoothing capacitor (Cs) between this drive supply line (140, 240) with its conductive barrier material (240) and the further supply line (230) of the LED upper electrodes (23) extending on an insulating coating (40) over the top of the conductive barrier material (240).

Title: Wiring structure
Inventor: KAMOSHIMA TAKAO
IPC: H01L21/82
Filed: 2003-03-20
Granted: 2004-06-11
Abstract: The present invention protects a wiring against an etchant when a fuse connected to this wiring is subjected to a laser blow. A fuse has a barrier metal at its lower side. A plug is connected to the lower side of the fuse. The plug has a barrier metal at least at its lower side. Even if the fuse is partly removed through the laser blow at a region other than a portion where the fuse is connected to the plug, two layers of the barrier metals remain between the removed portion and a lower wiring. This enlarges the margin for preventing the adverse influence, such as corrosion and breaking of the lower wiring, brought by an etchant associated in other manufacturing process.
