  • Patent number: 8243532
    Abstract: A structure and method for increasing the operating speed and reducing the overall programming time of a memory array are provided herein. The method and structure reduce the maximum write current consumption, for writing a plurality of data bits to a NVM array, by writing the data bits sharing an activated word line at different times (e.g., activating bit lines associated with an activated word line at different times). The write operation of respective data bits, which individually utilize only a fraction of the overall write window of the bits, are interleaved so that the maximum write current of respective bits are offset in time from the maximum write current of another bit, allowing a larger number of data bits to be written without exceeding system specifications (e.g., maximum current) and reducing overall memory write time.

  • Patent number: 8241425
    Abstract: The present invention is directed to an apparatus and method of forming a thermos layer surrounding a chuck for holding a wafer during ion implantation. The thermos layer is located below a clamping surface, and comprises a vacuum gap and an outer casing encapsulating the vacuum gap. The thermos layer provides a barrier blocking condensation to the outside of the chuck within a process chamber by substantially preventing heat transfer between the chuck when it is cooled and the warmer environment within the process chamber.

  • Patent number: 8237135
    Abstract: An ion implantation method and system that incorporate beam neutralization to mitigate beam blowup, which can be particularly problematic in low-energy, high-current ion beams. The beam neutralization component can be located in the system where blowup is likely to occur. The neutralization component includes a varying energizing field generating component that generates plasma that neutralizes the ion beam and thereby mitigates beam blowup. The energizing field is generated with varying frequency and/or field strength in order to maintain the neutralizing plasma while mitigating the creation of plasma sheaths that reduce the effects of the neutralizing plasma.

  • Patent number: 8228658
    Abstract: A method for clamping a workpiece involves placing the workpiece on a clamping surface of an electrostatic clamp. A clamping voltage is applied to the electrostatic clamp at a first frequency, therein providing a first clamping force between the workpiece and the electrostatic clamp. The application of clamping voltage at the first frequency is halted and another clamping voltage at a second frequency is applied to the electrostatic clamp, therein providing a second clamping force between the workpiece and the electrostatic clamp. The second frequency is greater than the first frequency, wherein the second clamping force is less than the first clamping force. The application of the clamping voltage at the second frequency is then halted, and the workpiece is removed from the electrostatic clamp. The clamping voltage can be controlled based on a set of performance criteria, such as a desired minimum clamping force and a maximum de-clamp time.

  • Patent number: 8227773
    Abstract: A glitch duration threshold is determined based on an allowable dose uniformity, a number of passes of a workpiece through an ion beam, a translation velocity, and a beam size. A beam dropout checking routine repeatedly measures beam current during implantation. A beam dropout counter is reset each time beam current is sufficient. On a first observation of beam dropout, a counter is incremented and a position of the workpiece is recorded. On each succeeding measurement, the counter is incremented if beam dropout continues, or reset if beam is sufficient. Thus, the counter indicates a length of each dropout in a unit associated with the measurement interval. The implant routine stops only when the counter exceeds the glitch duration threshold and a repair routine is performed, comprising recalculating the glitch duration threshold based on one fewer translations of the workpiece through the beam, and performing the implant routine starting at the stored position.

  • Patent number: 8212704
    Abstract: Aspects of the present disclosure relate to floating point timers and counters that are used in a variety of contexts. In some implementations, a floating point counter can be used to generate a wave form made up of a series of pulses with different pulse lengths. An array of these floating point counters can be used to implement a pool of delays. In other implementations, an array of floating point counters can be used to analyze waveforms on a number of different communication channels. Analysis of such waveforms may be useful in automotive applications, such as in wheel speed measurement for example, as well as other applications.
