摘要： A method for moving data in a memory system of a cascading region-based filter is disclosed. The method generally includes steps (A) to (C). Step (A) may load a first portion of the data from a buffer to the memory system at a start of a given cycle using a control circuit. The memory system generally has multiple first memories. A first region of a particular first memory may receive the first portion of data. Step (B) may copy the data in a second region of the particular first memory to a third region of the particular first memory at an end of the given cycle. Step (C) may copy the data in an output region of the particular first memory to an input region of a next first memory at the end of the given cycle. The output region generally overlaps both the first region and the second region.

摘要： An improved and new process for fabricating self-aligned contacts (SAC) to source/drain areas of complimentary (CMOS) FET's has been developed using a non-conformal layer of silicon nitride, eliminating the need for a hard mask. This process allows for “zero” spacing from contact structure to polysilicon gate structure, for closely spaced design rule gates. Some key process features of this invention are as follows: no hard mask is needed and the gate process is exactly the same as “standard” logic process. The process differences are that between the S/D implant, salicidation and the normal contact process, there is inserted a non-conformal CVD silicon nitride deposition with a SAC pattern and etch process. The process is fully compatible with both state of-the-art salicide and polycide processes. The self-aligned contact process simplifies processing, while yielding improvements in electrical device performance and reliability. The process is very useful for the “standard” logic device salicided processes.

摘要： A new method of forming MOS transistors with self-aligned silicide has been achieved. A gate oxide layer is formed overlying a semiconductor substrate. A polysilicon layer is deposited. The polysilicon layer and the gate oxide layer are patterned to form gates. Ions are implanted to form lightly doped drain regions. A dielectric layer is deposited. The dielectric layer is polished down to expose the top surface of the gates. The dielectric layer is then anisotropically etched down to form dielectric sidewall spacers. The dielectric sidewall spacers cover a portion of the vertical sidewalls of the gates while exposing a portion of the vertical sidewalls of the gates. Ions are implanted to form source and drain regions. A metal layer is deposited. Contact surfaces are formed between the metal layer with: the exposed top surfaces of the gates, the exposed portions of the vertical sidewalls of the gates, and the exposed source and drain regions. The integrated circuit device is annealed to react the metal layer and the polysilicon layer and silicon to selectively form a silicide layer in the surface of the polysilicon layer and in the surface of the semiconductor substrate at the contact surfaces. The remaining metal layer is removed to complete the device.
