摘要： Image sensors and color filter arrays for in-pixel charge summing and interlaced readout modes may be provided. An image sensor that supports charge summing and interlaced readout modes may include an array of pixels with pairs of adjacent green, red, and blue light-sensitive pixels. An image sensor may implement an in-pixel charge summing readout mode in which charges from pairs of pixels are summed onto a common node and then read out from the common node. An image sensor may implement an interlaced readout mode in which image data is read out from alternating rows of the image sensor. An image sensor may use a shared readout scheme in which a group of four pixels is formed from two pairs of commonly-colored pixels. The four pixels may share circuitry such as a reset transistor, a buffer transistor, and a row select transistor and may connect to a single readout line.

摘要： A method of operating an imager to have increased capacitance on a pixel output or column output line during most reset signal and pixel signal sampling operations from the line. The increased capacitance is achieved by switching in multiple sample and hold capacitors during the sampling operations.

摘要： A method for establishing an electrical connection includes drawing at least one of a member of an electrical connector and a contact in communication with at least one device. The drawing may be affected nonrigidly. It may occur in a direction substantially normal to a plane of the semiconductor device. Attractive forces, such as magnetic attraction, may cause the drawing. The establishment of electrical connection in this manner may be used in stress testing of semiconductor devices or to otherwise establish an electrical connection between one or more semiconductor devices and a ground, or power source.

摘要： A pixel with a photosensor and a transfer transistor having a split transfer gate. A first section of the transfer gate is connectable to a first voltage source while a second section of the transfer gate is connectable to a second voltage source. Thus, during a charge integration period of a photosensor, the two sections of the transfer gate may be oppositely biased to decrease dark current while controlling blooming of electrons within and out of the pixel cell. During charge transfer the two gate sections may be commonly connected to a positive voltage sufficient to transfer charge from the photosensor to a floating diffusion region.
