  • Patent number: 7825438
    Abstract: A CMOS image sensor cell includes a semiconductor active region of first conductivity type having a surface thereon and a P-N junction photodiode in the active region. A drive transistor is also provided in the semiconductor active region. The drive transistor has a gate electrode that is configured to receive charge generated in the P-N junction photodiode during an image capture operation (i.e., during capture of photons received from an image). This drive transistor has a gate electrode and a contoured channel region extending underneath the gate electrode. The contoured channel region has an effective channel length greater than a length of the gate electrode.

  • Patent number: 7750280
    Abstract: A back-illuminated image sensor may include a substrate in which photodiodes are disposed; an insulating layer on a first surface of the substrate; an interconnection layer in the insulating layer; an anti-reflection layer between the substrate and the insulating layer; a plurality of color filters on a second surface of the substrate opposite to the first surface; and a microlens on the color filters. Because the anti-reflection layer may be between the substrate and an interlayer dielectric layer, the reflection rate of light that passes through the substrate and arrives at an interface between the substrate and the interlayer insulating layer may be reduced.

  • Patent number: 7375389
    Abstract: Provided are semiconductor devices having a system-on-chip (SOC) configuration that combines both a capacitor-based cell-array memory region and one or more MOS core/peripheral circuit/logic regions on a single chip and a method for manufacturing such devices. The manufacturing process reduces the number of additional photolithographic processes required and modifies the relationship between the sizing of various layers and/or structures to reduce the fabrication cost and improve the reliability of the resulting devices. In particular, the capacitors for the memory region are formed in the same insulating layer as the first metal pattern for the core/peripheral circuit/logic regions of the devices, thereby producing capacitors and metal patterns of substantially the same height and thickness respectively. A landing structure may also be formed in the cell array region in combination with the first metal pattern for improving the contact process in the cell array region.

  • Publication number: 20080036022
    Abstract: An image sensor and a method of manufacturing same is disclosed. The image sensor implements a reflecting film formed on a front surface of a substrate having a back-illuminated photodetector. The reflecting film operates to reflect wavelengths of light that were not received by the photodetector back to the photodetector to increase the overall sensitivity of the image detector. The reflective film is formed by layering different thicknesses of material with different indices of refraction, resulting in a high reflectance.
