Abstract: Disclosed are embodiments of a device and method of forming the device that utilize metal ion migration under controllable conditions. The device embodiments comprise two metal electrodes separated by one or more different dielectric materials. One electrode is sealed from the dielectric material, the other is not. The device is adapted to allow controlled migration of embedded metal ions from the unsealed electrode into dielectric material to form a conductive path under field between the electrodes and, thereby, to decrease the resistance of the dielectric material. Reversing the field causes the metal ions to reverse their migration, to break the conductive metallic path between the electrodes and, thereby, to increase the resistance of the dielectric material. Thus, the device can comprise a simple switch or programmable resistor.

Abstract: A method forms a gate conductor over a substrate, forms spacers (e.g., nitride spacers) on sides of the gate conductor, and implants an impurity into exposed regions of the substrate not protected by the gate conductor and the spacers. Then the method forms a silicide on surfaces of the exposed regions of the substrate. The method forms a conformal protective layer (e.g., an oxide or other similar material) over the silicide, the spacers, and the gate conductor. Next, the method forms a non-conformal sacrificial layer (e.g., nitride or other material that can be selectively removed with respect to the protective layer) over the protective layer. A subsequent partial etching process partially etches the sacrificial layer such that relatively thinner regions of the sacrificial layer that are over the spacers are completely removed and the relatively thicker regions of the sacrificial layer that are over the substrate are not removed.

Abstract: A router (101) includes one or more input ports (104) and one or more output ports (112). The router (101) includes a lookup table (105) to determine routing of the incoming packets or cells. The lookup table is implemented in dynamic random access memory (DRAM) with a portion implemented as static random access memory (SRAM) (202, 204). The SRAM (204) is used to store a first search level of destination addresses. Once the first search level in SRAM (204) has been exhausted, the search moves to the DRAM portion (202).

Abstract: A conductor with improved magnetic field per current ratio is disclosed. The conductor includes a magnetic liner lining a second surface and sides thereof. The magnetic liner is preferably a super-paramagnet with high susceptibility or a ferromagnet with a microstructure where the size of the non-exchanged coupled micro domains is so small that their energy content is close to or small compared to kT that such films have super-paramagnetic properties and essentially behave like a paramagnet with high susceptibility.

Abstract: CMP of integrated circuits containing DRAM arrays with trench capacitors fill the trenches with oxide, resulting in a an array of oxide structures that is dense compared with the concentration in the surrounding support structures and therefore has a higher loading. A conformal layer is deposited over the wafer, increasing the loading in the array, but filling in spaces between active areas. A blanket etch removes material in both the array and the supports. A block etch balances the amount of material in the array and the supports. A supplementary oxide deposition in the array fills spaces between the structures to a nearly uniform density.

Abstract: A structure and method which enables the deposit of a thin nitride liner just before Trench Top Oxide TTO (High Density Plasma) HDP deposition during the formation of a vertical MOSFET DRAM cell device. This liner is subsequently removed after TTO sidewall etch. One function of this liner is to protect the collar oxide from being etched during the TTO oxide sidewall etch and generally provides lateral etch protection which is not realized in the current processing scheme. The process sequence does not rely on previously deposited films for collar protection, and decouples TTO sidewall etch protection from previous processing steps to provide additional process flexibility, such as allowing a thinner strap Cut Mask nitride and greater nitride etching during node nitride removal and buried strap nitrided interface removal.

Abstract: A semiconductor wafer testing system tests one or more die clusters on a semiconductor wafer, using a test circuit to test multiple sections or areas of each die in parallel. The semiconductor wafer testing system has a buffer connected to the die cluster via the test circuit. The buffer writes test data onto a section of each die in the die cluster. The buffer reads test data from the section of each die in the die cluster.

Abstract: A method of forming at least one deep trench structure having an increased trench depth is provided. The method includes providing at least one deep trench having sidewalls that extend to a common bottom wall in a surface of a substrate. Each deep trench has initial dimensions that are wider than targeted dimensions for the deep trenches. To reduce the initial dimensions to that of the targeted dimensions, an epitaxial silicon film is formed selectively or non-selectively on at least some portions of the sidewalls using a low-temperature ultra-high vacuum epitaxial silicon growth tehnique.

Abstract: A linked list DMA descriptor includes an indication of a number of data pointers contained in a subsequent DMA descriptor. The number of data pointers contained in the subsequent DMA descriptor is preferably contained in the memory address of the subsequent DMA descriptor. The number of data pointers is stored by the DMA controller and controls how many read cycles are performed when processing the subsequent DMA descriptor.

Abstract: A configurable adaptive filter that is used for echo cancellation is disclosed, which includes a method of detecting a voice or no-voice signal. The presence of a voice or no-voice signal is determined by calculating a histogram of signal amplitude value over a period of time. If this histogram has more than a predefined number of samples that are above a threshold then the signal is classified as no-voice or periodic otherwise the signal is classified as a voice signal. A variable maximum amplitude limit and lower amplitude thresholds are disclosed to detect a voice or no-voice from the histogram signal faster than traditional methods utilized in echo cancelers. A configurable hysteresis time is used to ensure the signal register primarily contains voice signal when the filter coefficients of the echo canceler are allowed to adapt.
