    摘要: The present invention provides processes for doping and saliciding word lines in a virtual ground array flash memory device without causing shorting between bit lines. According to one aspect of the invention, word lines are doped prior to patterning the poly layer from which the word lines are formed in the core region. Thereby, the poly layer protects the substrate between the word lines from doping that could cause shorting between bit lines. According to another aspect of the invention, word lines are exposed while spacer material, dielectric, or like material protects the substrate between word lines. The spacer material or dielectric prevents the substrate from becoming salicided in a manner that, like doping, could cause shorting between bit lines. The invention provides virtual ground array flash memory devices with doped and salicided word lines, but no shorting between bit lines even in virtual ground arrays where there are no oxide island isolation regions between bit lines.

    摘要: A semiconductor device for minimizing auto-doping problems is disclosed. An etch stop layer is eliminated and is replaced with a consumable liner oxide layer so that stacked gate structures of the device can be positioned closer together, thus permitting shrinking of the device. The liner oxide layer is formed directly over a substrate and in contact with stacked gate structures, sidewall spacers, and sources and drains formed on the substrate, and serves as an auto-doping barrier for the dielectric layer to prevent boron and phosphorous formed in the dielectric layer from auto-doping into the sources and drains.

    摘要: A predetermined species such as nitrogen is placed at an interface between a bit line junction and a dielectric layer of a control dielectric structure of a flash memory device to minimize degradation of such an interface by minimizing formation of interface defects during program or erase operations of the flash memory device. The predetermined species such as nitrogen is implanted into a bit line junction of the flash memory device. A thermal process is performed that heats up the semiconductor wafer such that the predetermined species such as nitrogen implanted within the semiconductor wafer thermally drifts to the interface between the bit line junction and the control dielectric structure during the thermal process. The predetermined species such as nitrogen at the interface minimizes formation of interface defects and thus degradation of the interface with time during the program or erase operations of the flash memory device.

    摘要: Outgassing from a dielectric gap fill layer, e.g., a low dielectric constant material such as HSQ, and attendant deformation or delamination of a barrier dielectric layer on an overlying patterned conductive layer during subsequent thermal processing are avoided or significantly reduced by controlling the thickness of the dielectric cap layer on the dielectric gap fill layer. Embodiments include depositing a conformal SiON barrier on a first conductive pattern, depositing a HSQ gap fill layer on the conformal SiON barrier layer, depositing a silicon oxide cap layer and planarizing such that the thickness of the planarized silicon cap layer is at least 2500 .ANG., thereby avoiding deformation and/or delamination of a conformal SiON barrier layer on an overlying patterned conductive layer during subsequent thermal processing.

    摘要: A wet etching process for establishing isolation grooves in a flash memory core wafer includes depositing nitride and/or oxide layers on a silicon substrate of the wafer, depositing a photoresist layer thereon, and then exposing predetermined portions of the photoresist layer to ultraviolet light to establish a desired groove pattern in the photoresist layer. A dry etching process is then used to remove the nitride and/or oxide layers beneath the groove pattern of the photoresist layer to thereby expose portions of the substrate. Next, the wafer is disposed in a wet etching solution such as potassium hydroxide to form grooves in the exposed portions of the silicon substrate. The wafer is oriented and disposed in the bath as appropriate for forming V-shaped grooves, such that after etching, the angled walls of the grooves can be easily exposed to a dopant beam directly above the wafer, without having to tilt the wafer or beam source. Thereby, the walls of the grooves are easily implanted with dopant.

    摘要: A non-volatile memory device is formed in a substrate, thereby enabling increased densification. Embodiments include forming a trench in a substrate, forming a substantially U-shaped tunnel dielectric layer in the trench, depositing a substantially U-shaped floating gate electrode on the tunnel dielectric layer, forming a dielectric layer on the floating gate electrode extending on the substrate surface and forming a substantially T-shaped control gate electrode filling the trench and extending on the substrate. Sidewall spacers are formed on side surfaces of the control gate electrode and dielectric layer, followed by ion implantation to form source/drain regions extending into the substrate to substantially the same depth, leaving a region containing an impurity of the first conductivity type at the intersection of the trench and substrate surface which prevents shorting between the source/drain region and gate electrodes.

    摘要: A process for protecting the stacked gate edge of a semiconductor device is disclosed. The process provides for providing a spacer formation before the self aligned source (SAS) etch is accomplished. By providing the spacer formation prior to the SAS etch, tunnel oxide integrity is much improved and the source junction implant profile is much more uniform because the silicon around the source region is not gouged away.

    摘要: Aspects of the generation of new robotic motion trajectories are described. In one embodiment, a new robot motion trajectory may be generated by gathering demonstrated motion trajectories, adapting the demonstrated motion trajectories into robot-reachable motion trajectories based on a joint space of a robot model, for example, and generating motion harmonics with reference to the motion trajectories. Further, one or more constraints may be specified for a new goal. The weights of the motion harmonics may then be searched to identify or generate a new motion trajectory for a robot, where the new motion minimizes discrepancy from the demonstrated motion trajectories and error due to the at least one constraint. In the new motion trajectory, the degree to which the constraints are satisfied may be tuned using a weight. According to the embodiments, new motion variants may be generated without the need to learn or review new demonstrated trajectories.
