  • MEMORY DEVICE, FAILURE BITS DETECTOR AND FAILURE BITS DETECTION METHOD THEREOF
    Publication number: 20240120018
    Abstract: A memory device, a failure bits detector, and a failure bits detection method thereof are provided. The failure bits detector includes a current generator, a current mirror, and a comparator. The current generator generates a first current according to a reference code. The current mirror mirrors the first current to generate a second current at a second end of the current mirror. The comparator compares a first voltage at a first input end with a second voltage at a second input end to generate a detection result.

  • Damper for a gauge sensor in a dry etch chamber
    Patent number: 7043991
    Abstract: A damper for protecting a gauge sensor measuring the pressure of a dry etch chamber. The damper includes a vacuum tube for connecting the gauge with the chamber and at least one plate for blocking the plasma of the chamber from directly striking against the sensor. The at least one plate is disposed at the inner wall of the vacuum tube to effectively prevent the plasma from attaching onto the sensor so as to maintain the sensitivity of the sensor and prolong the lifetime of the gauge.
