    摘要： Imager pixels with low-level interconnect sections, methods of assembling imager pixels with low-level interconnect sections, and systems containing imager pixels with low-level interconnect sections. Imager pixels are formed such that specific interconnections between transistors and other components of an imager array are removed from one or more upper level metallization sections and placed on a low-level interconnect section closer to the photodetector, such that one upper metallization section is eliminated.

    摘要： Methods and apparatuses using four-way-shared readout circuits to increase pixel fill factor. Embodiments consolidate circuits from several pixels, reducing the number of components in each pixel and this increasing the fill factor of each pixel. Additionally, embodiments use “straight gate” transfer gates to increase the readout speed and symmetry of the smaller pixels.

    摘要： A photo acid generator (PAG) or an acid is used to reduce resist scumming and footing. Diffusion of acid from photoresist into neighbors causes a decreased acid level, and thus causes resist scumming. An increased acid layer beneath the resist prevents acid diffusion. In one embodiment, the increased acid layer is a layer of spun-on acid or PAG dissolved in aqueous solution. In another embodiment, the increased acid layer is a hard mask material with a PAG or an acid mixed into the material. The high acid content inhibits the diffusion of acid from the photoresist into neighboring layers, and thus substantially reduces photoresist scumming and footing.

    摘要： An image sensor has an array of pixels of different colors. The pixels may be arranged in a repeating pattern of eight pixels having four rows and two columns. During charge summing operations, the first and third rows may share a floating diffusion and the second and fourth rows may share a floating diffusion. When charge summing is inactive, transfer gates in the first and second columns may be controlled independently, while transfer gates in pairs of rows may be controlled simultaneously. When charge summing is active, summed charges from pixels of the same color in the first and third rows may be placed on the floating diffusion shared by the first and third rows and summed charges from pixels of the same color in the second and fourth rows may be placed on the floating diffusion shared by the second and fourth rows.
