  • Publication number: 20070092986
    Abstract: This invention provides a CMOS image sensor having a pinned photodiode. A P substrate is provided having thereon a P well. The P well is adjacent to a light-sensing region of the CMOS image sensor. A gate electrode of a transfer transistor of the CMOS image sensor is formed on the P well. A self-aligned implantation is performed to form N-type diode diffusion within the light-sensing region. An oblique ion implantation process is then performed to form N-type pocket diffusion directly under the gate electrode. Spacers are formed on sidewalls of the gate electrode. A surface P+ pinning diffusion region is then formed in the diode diffusion region.

  • Patent number: 7208404
    Abstract: A method of forming a copper interconnect in an opening within a pattern is described. The copper interconnect has an Rs that is nearly independent of opening width and pattern density. A first copper layer having a concave upper surface and thickness t1 is formed in a via or trench in a dielectric layer by depositing copper and performing a first CMP step. A second copper layer with a thickness t2 where t2?t1 and having a convex lower surface is deposited on the first copper layer by a selective electroplating method. The first and second copper layers are annealed and then a second CMP step planarizes the second copper layer to become coplanar with the dielectric layer. The invention is also a copper interconnect comprised of the aforementioned copper layers where the first copper layer has a grain density (GD1)?GD2 for the second copper layer.

  • Publication number: 20070088908
    Abstract: The present invention discloses a method for arranging heap memory. The method is to utilize a memory-management function library positioned in the run-time library for use during run time and designate two sets of heap memory, wherein one set of heap memory is arranged in a dynamic random access memory (DRAM) whereas the other set of heap memory is arranged in a static random access memory (SRAM). In addition, an application program interface is added to indicate a start point and size of the heap memory. Furthermore, a parameter is added to the application program interface for calling one set of heap memory when allocating memory. By doing so, the programmer can select a position to allocate the memory according to the executable content. Therefore, when the processor is executing calculation or accessing memory, the efficiency can be well enhanced.
