    摘要: A structural alternative to retro doping to reduce transistor leakage is provided by providing a liner in a trench, undercutting a conduction channel region in an active semiconductor layer, etching a side, corner and/or bottom of the conduction channel where the undercut exposes semiconductor material in the active layer and replacing the removed portion of the conduction channel with insulator. This shaping of the conduction channel increases the distance to adjacent circuit elements which, if charged, could otherwise induce a voltage and cause a change in back-channel threshold in regions of the conduction channel and narrows and reduces cross-sectional area of the channel where the conduction in the channel is not well-controlled; both of which effects significantly reduce leakage of the transistor.

    摘要: A deep trench is formed to a depth midway into a buried insulator layer of a semiconductor-on-insulator (SOI) substrate. A top semiconductor layer is laterally recessed by an isotropic etch that is selective to the buried insulator layer. The deep trench is then etched below a bottom surface of the buried insulator layer. Ion implantation is performed at an angle into the deep trench to dope the sidewalls of the deep trench beneath the buried insulator layer, while the laterally recessed sidewalls of the top semiconductor layer are not implanted with dopant ions. A node dielectric and trench fill materials are deposited into the deep trench. A buried strap has an upper buried strap sidewall that is offset from a lower buried strap sidewall and a deep trench sidewall.

    摘要: Disclosed are embodiments of memory circuit having two discrete memory devices with two discrete memory arrays that store essentially identical data banks. The first device is a conventional memory adapted to perform all maintenance operations that require read functions (i.e., all update and refresh operations). The second device is a DRAM-based CAM device adapted to perform parallel search and overwrite operations only. Performance of overwrite operations by the second device occurs in conjunction with performance of maintenance operations by the first device so that corresponding memory cells in the two devices store essentially identical data values. Since the data banks in the memory devices are essentially identical and since maintenance and parallel search operations are not performed by the same device, the parallel search operations can be performed without interruption. Also disclosed are embodiments of an associated design structure and method.

    摘要: By controlling buried plate doping level and bias condition, different capacitances can be obtained from capacitors on the same chip with the same layout and deep trench process. The capacitors may be storage capacitors of DRAM/eDRAM cells. The doping concentration may be less than 3E19cm−3, a voltage difference between the biases of the buried electrodes may be at least 0.5V, and a capacitance of one capacitor may be at least 1.2 times, such as 2.0 times the capacitance of another capacitor.

    摘要: A memory cell has an access transistor and a capacitor with an electrode disposed within a deep trench. STI oxide covers at least a portion of the electrode, and a liner covers a remaining portion of the electrode. The liner may be a layer of nitride over a layer of oxide. Some of the STI may cover a portion of the liner. In a memory array a pass wordline may be isolated from the electrode by the STI oxide and the liner.

    摘要: A concurrent refresh mode is realized by allowing a memory array to be refreshed by way of a refresh bank select signal, while concurrently enabling a memory access operation in another array. The refresh address management is greatly simplified by the insertion of row address counter integrated within each array. In the preferred embodiment, any combination of a plurality of the memory arrays is refreshed simultaneously while enabling a memory access operation. This concurrent mode also supports a multi-bank operation.
