    摘要: An advanced contact integration technique for deep-sub-150 nm semiconductor devices such as W/WN gate electrodes, dual work function gates, dual gate MOSFETs and SOI devices. This technique integrates self-aligned raised source/drain contact processes with a process employing a W-Salicide combined with ion mixing implantation. The contact integration technique realizes junctions having low contact resistance (RC), with ultra-shallow contact junction depth (XJC) and high doping concentration in the silicide contact interface (Nc).

    摘要: In accordance with the invention, a method for opening holes for semiconductor fabrication includes the steps of providing a pad stack on a substrate, forming a hard mask layer on the pad stack, the hard mask layer selectively removable relative to the pad stack, patterning a resist layer on the hard mask layer, the resist layer being selectively removable relative to the hard mask layer and having a thickness sufficient to prevent scalloping, etching the hard mask layer selective to the resist layer down to the pad stack, removing the resist layer. After removing the resist layer, the pad stack is etched selective to the hard mask layer such that a hole is opened down to the substrate.

    摘要: An alternating phase shift mask with dark loops thereon, a memory array fabricated with the alternating phase shift mask, and a method of fabricating the memory. The dark loops in the mask always separate first regions with 180° phase difference from second regions with 0° phase difference to define active areas or gate-lines in a DRAM chip. By using the alternating phase shift mask to pattern gate-lines or active areas in a DRAM array, no unwanted image is created in the DRAM array and only one exposure is needed to achieve high resolution requirement.

    摘要: The invention is related to a DRAM cell arrangement with vertical MOS transistors. Channel regions arranged along one of the columns of a memory cell matrix are parts of a rib which is surrounded by a gate dielectric layer. Gate electrodes of the MOS transistors belonging to one row are parts of a strip-like word line, so that at each crossing point of the memory cell matrix there is a vertical dual-gate MOS transistor with gate electrodes of the associated word line formed in the trenches on both sides of the associated rib.

    摘要: A dynamic random access memory (DRAM) device having a vertical transistor and an internally-connected strap (ICS) to connect the transistor to the capacitor. The ICS makes no direct contact with the substrate. The DRAM cell operates at a substantially lower cell capacitance than that required for a conventional buried strap trench (BEST) cell without causing any negative impact on device performance. The lower cell capacitance also extends the feasibility of deep trench capacitor manufacturing technology without requiring new materials or processing methods. A method of manufacturing the DRAM includes forming a very thin Si layer on top of a DT cell while at the same time the method forms an isolated layer replacing a conventional collar. The formation of the SOI by internal thermal oxidation (ITO) makes the structure in such a manner that the device may be fully depleted.
