    Abstract: A process for fabricating a vertical MOSFET device for use in integrated circuits is disclosed. In the process, at least three layers of material are formed sequentially on a semiconductor substrate. The three layers are arranged such that the second layer is interposed between the first and third layers. The second layer is sacrificial, that is, the layer is completely removed during subsequent processing. The thickness of the second layer defines the physical gate length of the vertical MOSFET. In the process the first and third layers have etch rates that are significantly lower than the etch rate of the second layer in an etchant selected to remove the second layer. The top layer, which is either the third or subsequent layer, is a stop layer for a subsequently performed mechanical polishing step that is used to remove materials formed over the at least three layers. After the at least three layers of material are formed on the substrate, a window or trench is formed in the layers. The window terminates at the surface of the silicon substrate in which one of either a source or drain region is formed in the silicon substrate. The window or trench is then filled with a semiconductor material. This semiconductor plug becomes the vertical channel of the transistor. Therefore the crystalline semiconductor plug is doped to form a source extension, a drain extension, and a channel region in the plug. Subsequent processing forms the other of a source or drain on top of the vertical channel and removes the sacrificial second material layer. The removal of the sacrificial second layer exposes a portion of the doped semiconductor plug. The device gate dielectric is then formed on the exposed portion of the doped semiconductor plug. The gate electrode is then deposited. The physical gate length of the resulting device corresponds to the deposited thickness of the second material layer.

    Abstract: Disclosed are two mechanisms for preventing access failures attributable to dynamic port assignment of firewall-blocked ports. The mechanism involves an enhanced firewall that opens blocked ports prior to possible dynamic allocation so that the blocked ports are not available when a port is requested. The second mechanism involves an enhanced commutations stack that works in conjunction with an enhanced firewall to reserve blocked ports so that the blocked ports are not available for dynamic allocation when a port is requested.

    Abstract: A capacitor charging circuit for charging a defibrillation capacitor in a constant period of time regardless of battery voltage by employing a controlled duty cycle charging technique. The defibrillation capacitor is charged in a piecemeal manner through a transistor and flyback transformer circuit. The gate of the transistor is driven by a constant frequency pulse train inverter drive signal in which voltage is conveyed to the capacitors during one-half of the full cycle of the pulse train. The primary of the transformer is controlled by each pulse of the inverter drive signal so that the secondary of the transformer supplies current to the defibrillation capacitors during the off half cycle of the drive signal, the charge being built up in the defibrillation capacitors incrementally during the off half cycle of the inverter drive signal until the predetermined voltage is reached.

    Abstract: A temporary pacemaker combines technologies of the implantable pacemaker, the waterproof watch, with a separate remote-control programming unit that communicates with the pacemaker via IR radiation. An LCD readout on the temporary pacemaker continuously reports on current settings, and is monitored periodically, as well as during the setting process. The programming unit is aimed at an IR sensor on the pacemaker, and its dedicated controls are used for setting, with the aid of prompting messages on its own LCD panel. Battery life is about 6-9 months, while that for the lithium battery in the sealed and sterilizable pacemaker approaches five years.A multi-conductor connector and an adapter for use with a temporary external pacemaker, is disclosed which reduces the complexity of connecting temporary pacing leads, adapters, extension cables, heart wires or other miscellaneous cables to a pacing device. It also reduces the possibility of inadvertent removal/disconnection of these patient connected cable systems, and yet allows for a quick release.
