Patent number: 7339246Abstract: The invention relates to a large-area sensor arrangement, notably a flat dynamic X-ray detector (FDXD). The light-sensitive and/or X-ray-sensitive sensors (pixels) of the sensor arrangement are arranged in a planar distribution on a substrate (1), thus forming a sensitive layer (20). On the top surface of the layer (20) there is provided a contact point (23) for each sensor, which contact point is connected to an integrated circuit (6) via one or more connection layers (30, 40).

Patent number: 7304324Abstract: An example memory includes an address control portion, a protection film, a property deterioration material layer, data storage areas, and bonding pads. The protection film protects an organic semiconductor layer of a semiconductor circuit and prevents intrusion of moisture or chemical molecules in the air, light, or the like, into the organic semiconductor layer.

Patent number: 7301184Abstract: Shift register electrodes are formed in an imaging area and a peripheral area through use of a single layer of conductive film, and a thick insulating film is deposited over those electrodes and planarized. The thick insulating film overlying the shift register electrodes in the peripheral area is kept as it is and on the other hand, the thick insulating film overlying the shift register electrodes is etched to just fill gaps between the shift register electrodes with the film, thereby allowing a light shielding metal layer overlying the shift register electrodes in the peripheral area and insulating films sandwiched therebetween to be formed without discontinuity. Since metal interconnect lines in the peripheral area have a thick and planarized insulating film formed thereunder, parasitic capacitance between diffusion layers/electrodes and the metal interconnect lines can be reduced, leading to reduction in power consumption of image sensor.Type: GrantFiled: September 9, 2003Date of Patent: November 27, 2007Assignee: NEC Electronics CorporationInventor: Toru Kawasaki
