摘要:
Methods of manufacturing trench-bounded buried-channel p-type metal oxide semiconductor field effect transistors (p-MOSFETs), as used in dynamic random access memory (DRAM) technologies, for significantly reducing the anomalous buried-channel p-MOSFET sensitivity to device width. In one embodiment, the method comprises the initiation of a low temperature annealing step using an inert gas after the deep phosphorous n-well implant step, and prior to the boron buried-channel implant and 850.degree. C. gate oxidation steps. Alternatively, the annealing step may be performed after the boron buried-channel implant and prior to the 850.degree. C. gate oxidation step. In another embodiment, a rapid thermal oxidation (RTO) step is substituted for the 850.degree. C. gate oxidation step, following the deep phosphorous n-well and boron buried-channel implant steps. Alternatively, an 850.degree. C. gate oxidation step may follow the RTO gate oxidation step.

摘要:
Methods of forming a semiconductor structure having FinFET's and planar devices, such as MOSFET's, on a common substrate by a damascene approach, and semiconductor structures formed by the methods. A semiconductor fin of the FinFET is formed on a substrate with damascene processing in which the fin growth may be interrupted to implant ions that are subsequently transformed into a region that electrically isolates the fin from the substrate. The isolation region is self-aligned with the fin because the mask used to form the damascene-body fin also serves as an implantation mask for the implanted ions. The fin may be supported by the patterned layer during processing that forms the FinFET and, more specifically, the gate of the FinFET. The electrical isolation surrounding the FinFET may also be supplied by a self-aligned process that recesses the substrate about the FinFET and at least partially fills the recess with a dielectric material.

摘要:
An apparatus is provided for implementing an enhanced hand shake protocol for microelectronic communication systems. A transmitter and a receiver is coupled together by a transmission link. The transmitter receives an idle input. The idle input is activated when the transmitter is not transmitting data and the transmitter applies a first common 10 mode level to the receiving unit. The idle input is deactivated when the transmitter is ready to transmit data and the transmitter raises the common mode level to the receiving unit. Responsive to the receiver detecting the common mode level up-movement, then the receiver receives the transmitted data signals. After the desired data has been sent, the 15 transmitter terminates communications, drops the common mode level with the idle input being activated.
摘要:
A semiconductor structure for a dynamic random access memory (DRAM) cell array that includes a plurality of vertical memory cells built on a semiconductor-on-insulator (SOI) wafer and a body contact electrically coupling a semiconductor body and a semiconductor substrate of the SOI wafer. The semiconductor body includes a channel region for the access device of one of the vertical memory cells. The body contact, which extends through a buried dielectric layer of the SOI wafer, provides a current leakage path that reduces the impact of floating body effects upon the vertical memory cell. The body contact may be formed by etching a via that extends through the semiconductor body and buried dielectric layer of the SOI wafer and extends into the substrate and partially filling the via with a conductive material that electrically couples the semiconductor body with the substrate.

Design structure embodied in a machine readable medium for designing, manufacturing, or testing a design. The design structure includes an interconnect structure with a liner formed on roughened dielectric material in an insulating layer and a conformal liner repair layer bridging that breaches in the liner. The conformal liner repair layer is formed of a conductive material, such as a cobalt-containing material. The conformal liner repair layer may be particularly useful for repairing discontinuities in a conductive liner disposed on roughened dielectric material bordering the trenches and vias of damascene interconnect structures.
