  • Publication number: 20080057652
    Abstract: Embodiments relate to an ion implantation method wherein a semiconductor substrate is divided into a core region, a high voltage region, and an I/O region. The core region and the I/O region are divided into a PMOS transistor region for forming PMOS transistors and an NMOS transistor region for forming NMOS transistors. The ion implantation method includes performing a first ion implantation process employing a first process condition on the NMOS transistor region of the substrate using a first mask, thus setting threshold voltages for the NMOS transistor region of the I/O region and for the high voltage region at the same time. A second ion implantation process employs a second process condition on the NMOS transistor region of the substrate using a second mask, thus setting a threshold voltage for the core region.

  • Publication number: 20080042220
    Abstract: A method for forming an LDD structure of a gate electrode of a MOSFET. The gate electrode may be formed by sequentially depositing a gate oxide layer and a poly silicon layer over a semiconductor substrate. A photo resist pattern may be formed over the resultant structure. A gate electrode may be formed by an etch using the photo resist pattern as a mask. An LDD area may be formed by ion implanting a low-concentration dopant using the gate electrode as a mask. After depositing a spacer layer over the upper surface of the substrate, a spacer may be formed by etching. A source/drain area may be formed by ion implanting a high-concentration dopant using the gate electrode and the spacer as a mask. A portion of the gate oxide layer where the gate oxide layer and the LLD area overlap may be removed by performing an etch process over the resultant structure.

  • Patent number: 7018093
    Abstract: In a temperature controlling apparatus for controlling temperature by using a temperature sensor, a defect state of the temperature sensor is sensed by sensing a change of specific resistance of the temperature sensor. A temperature value of the temperature sensor is detected at each unit time during exchanging of a chemical solution or stopping of a process in a chamber of the semiconductor fabricating process. A lowest temperature among the detected temperature values and a reference temperature predetermined to sense the change of the specific resistance of the temperature sensor, are compared with each other. When the lowest temperature deviates from the reference temperature, a defect of the temperature sensor is confirmed and a message indicative of a defect state and an alarm are generated.

  • Patent number: 6648824
    Abstract: All RF data received by transducers in response to an ultrasonic signal that was transmit-focused on a point along a predetermined scan lines are stored to compute display data for those points of an object that do not necessarily correspond to the pixels of the screen of a display device. For the determination of display data for each pixel point, reflected ultrasonic signals from multiple points around the point of interest are found and used to detect the peak of a waveform constituted by the reflected ultrasonic signals. With this scheme, the distortion due to conventional interpolation used for a limited number of scan lines can be greatly reduced.
