  • Publication number: 20070278557
    Abstract: An embedded memory device and method of forming MOS transistors having reduced masking requirements and defects using a single drain sided halo implant in the NMOS FLASH or EEPROM memory regions is discussed. The memory device comprises a memory region and a logic region. Logic transistors within the logic region have halos implanted at an angle underlying the channel from both drain and source region sides. Asymmetric memory cell transistors within the memory region receive a selective halo implant only from the drain side of the channel and not from the source side to form a larger halo on the drain side and leave a higher dopant concentration more deeply into the source side.

  • Publication number: 20070283418
    Abstract: A system for authenticating access to a data processing device or database is provided. The system includes a comparison module for comparing an attempt identifier with an account identifier, and a state-determining module for determining a state variable associated with at least one of the attempt identifier and the account identifier. The state-determining module determines the state variable by incrementing the state variable if the attempt identifier does not match the account identifier and if the state variable is less than a predetermined upper bound threshold, decrementing the state variable if the attempt identifier does match the account identifier and if the state variable is greater than a predetermined lower bound threshold, and authenticating the attempt identifier if the attempt identifier does match the account identifier and if the state variable equals the predetermined lower bound threshold.

  • Publication number: 20050212041
    Abstract: A method of forming an associated transistor is presented whereby short channel effects and junction capacitances are mitigated and enhanced switching speeds are thereby facilitated. Compensation regions are formed within a substrate by implanting dopants relatively deeply over source and drain regions formed within the substrate. The compensation regions are spaced apart slightly less than are the source and drain regions. This spacing affects potential contours and reduces junction capacitances within the transistor. The different distances between the source and drain regions and the compensation regions are achieved by forming and selectively adjusting sidewall spacers adjacent to a gate structure of the transistor. These spacers serve as guides for the dopants implanted into the substrate to form the source and drain regions and the compensation regions.

  • Patent number: 6940137
    Abstract: The present invention provides a semiconductor device 200 having an angled compensation implant, a method of manufacture therefore and a method of manufacturing an integrated circuit including the angled compensation implant. In one embodiment, the method of manufacturing the semiconductor device 200 includes creating a halo implant 240 in a substrate 210, introducing a compensation implant 260 in the substrate 210 at an angle abnormal to the substrate 210 and forming a source/drain region 250 above the compensation implant 260, the angle reducing a capacitance associated with the halo implant 240 or the source/drain region 250. The method further includes placing a gate structure 230 over the substrate 210.

  • Patent number: 6064759
    Abstract: An automatic inspection method and apparatus using structured light and machine vision cameras to inspect an object in conjunction with the geometric model of the object is disclosed. Camera images of the object are analyzed by computer to produce the location of points on the object's surfaces in three dimensions. During a setup phase before object inspection, the points are analyzed with respect to the geometric model computer file of the object. Many points are eliminated to reduce data-taking and analysis time to a minimum and to prevent extraneous reflections from producing errors. When similar objects are subsequently inspected, points from each surface of interest are spatially averaged to give high accuracy measurements of object dimensions. The inspection device uses several multiplexed sensors, each composed of a camera and a structured light source, to measure all sides of the object on a single pass. Calibration and compensation methods are also disclosed.
