摘要： A method of forming an SRAM cell device includes the following steps. Form pass gate FET transistors and form a pair of vertical pull-down FET transistors with a first common body and a first common source in a silicon layer patterned into parallel islands formed on a planar insulator. Etch down through upper diffusions between cross-coupled inverter FET transistors to form pull-down isolation spaces bisecting the upper strata of pull-up and pull-down drain regions of the pair of vertical pull-down FET transistors, with the isolation spaces reaching down to the common body strata. Form a pair of vertical pull-up FET transistors with a second common body and a second common drain. Then, connect the FET transistors to form an SRAM cell.

摘要： A MOSFET fabrication methodology and device structure, exhibiting improved gate activation characteristics. The gate doping that may be introduced while the source drain regions are protected by a damascene mandrel to allow for a very high doping in the gate conductors, without excessively forming deep source/drain diffusions. The high gate conductor doping minimizes the effects of electrical depletion of carriers in the gate conductor. The MOSFET fabrication methodology and device structure further results in a device having a lower gate conductor width less than the minimum lithographic minimum image, and a wider upper gate conductor portion width which may be greater than the minimum lithographic image. Since the effective channel length of the MOSFET is defined by the length of the lower gate portion, and the line resistance is determined by the width of the upper gate portion, both short channel performance and low gate resistance are satisfied simultaneously.
摘要翻译： MOSFET制造方法和器件结构，表现出改进的栅极激活特性。当源极漏极区域被镶嵌心轴保护以允许栅极导体中的非常高的掺杂而不会过度地形成深的源极/漏极扩散时，可以引入栅极掺杂。高栅极导体掺杂最大限度地减小了栅极导体中载流子的电耗损的影响。 MOSFET制造方法和器件结构进一步导致具有小于最小光刻最小图像的较低栅极导体宽度的器件，以及可能大于最小光刻图像的较宽上部栅极导体部分宽度。由于MOSFET的有效沟道长度由下栅极部分的长度限定，并且线路电阻由上部栅极部分的宽度决定，所以同时满足短沟道性能和低栅极电阻。

摘要： An integrated circuit chip is provided having both a conventional DRAM vertical transfer device and an integrated vertical storage capacitor or anti-fuse that can be accessed directly without having to turn on a transfer gate. The mechanism for accessing the integrated capacitor or anti-fuse directly can be a modified doping profile within the vertical cell that provides a low resistance punch-through FET. Alternatively, the mechanism can be a pair of overlapping or nearly overlapping diffusions within the vertical cell.
