The present invention relates to a technology with enables an image signal processor to output image data at a faster speed while using a memory having a smaller capacity. The image signal processor includes a pair of line memories for storing image data output from an analog-digital converter such that the image data alternates in units of horizontal lines, and outputting the stored image data in units of blocks according to a first-in-first-out method.

Image data output device for image signal processor

The present invention provides an image processing package comprising: an image sensor for receiving an image of a subject, which is incident from the outside, in the form of light and converting the image of the subject into an image signal; and an image signal processor for processing the image signal which is output from the image sensor and reproducing the image of the subject, wherein the image processing package has a structure in which the image sensor is vertically stacked on the image signal processor.

Image processing package and camera module having same

A semiconductor memory is formed by stacking a plurality of substrates and memory cells on each substrate are connected by data dump lines. A switch may intervene between the memory cell and the data dump line. When data of each substrate is dumped by the data dump line, a problem of decrease in a speed and an increase in power consumption due to a parasitic component can be minimized. Further, a core circuit including the memory cell may be disposed on one substrate and a peripheral circuit unit may be disposed on the remaining substrates.

Stack memory

A method for forming a pad in a wafer with a three-dimensional stacking structure is disclosed. The method includes bonding a device wafer that includes an Si substrate and a handling wafer, thinning a back side of the Si substrate, depositing an anti-reflective layer on the thinned back side of the Si substrate, depositing a back side dielectric layer on the anti-reflective layer, defining a space for a pad in the back side dielectric layer and forming vias that pass through the back side dielectric layer and the anti-reflective layer and contact back sides of super contacts which are formed on the Si substrate, filling one or more metals in the vias and the defined space for the pad, and removing a remnant amount of the metal filled in the space for the pad through planarization by a CMP (chemical mechanical polishing) process.

A unit pixel of an image sensor having a three-dimensional structure includes a first chip and a second chip which are stacked, one of the first chip and the second chip having a photodiode, and the other of the first chip and the second chip having a circuit for receiving information from the photodiode and outputting received information. The first chip includes a first pad which is projectedly disposed on an upper surface of the first chip in such a way as to define a concavo-convex structure, and the second chip includes a second pad which is depressedly disposed on an upper surface of the second chip in such a way as to define a concavo-convex structure corresponding to the concavo-convex structure of the first chip. The first chip and the second chip are mated with each other through bonding of the first pad and the second pad.
