  • Publication number: 20230067967
    Abstract: In a method of inspecting an extreme ultraviolet (EUV) radiation source, during an idle mode, a borescope mounted on a fixture is inserted through a first opening into a chamber of the EUV radiation source. The borescope includes a connection cable attached at a first end to a camera. The fixture includes an extendible section mounted from a first side on a lead screw, and the camera of the borescope is mounted on a second side, opposite to the first side, of the extendible section. The extendible section is extended to move the camera inside the chamber of the EUV radiation source. One or more images are acquired by the camera from inside the chamber of the EUV radiation source at one or more viewing positions. The one or more acquired images are analyzed to determine an amount of tin debris deposited inside the chamber of the EUV radiation source.

  • Patent number: 11582529
    Abstract: A satellite IRD (Integrated Receiver Decoder) complies with DiSEqC protocol and is capable of receiving a program of a specific channel from a single cable interface device through a cable. The DiSEqC transmitter transmits a first command corresponding to the specific channel to the single cable interface device through the I/O interface and the cable. The DiSEqC receiver acquires a second command transmitted on the cable through the I/O interface in response to the DiSEqC transmitter transmitting the first command. The detecting circuit compares the second command with the first command to generate a comparison result. The DiSEqC receiver monitors the I/O interface in response to the comparison result indicating that the first command and the second command are different to determine whether there is a command other than the first command transmitted on the cable.

  • Publication number: 20230015445
    Abstract: An operation power source for an operation power source supplying power to a synchronous rectifier controller is charged according to the invention. The synchronous rectifier controller controls a synchronous rectifier in response to a channel signal of the synchronous rectifier, generating SR ON times and SR OFF times. It is determined whether the channel signal resonates in a first SR OFF time, to provide an oscillation record accordingly. In a second SR OFF time after the first SR OFF time, in response to the oscillation record, a portion of resonance energy that causes the channel signal resonating is directed to charge the operation power source.

  • Publication number: 20220403549
    Abstract: Methods for determining suitability of Czochralski growth conditions to produce silicon substrates for epitaxy. The methods involve evaluating substrates sliced from ingots grown under different growth conditions (e.g., impurity profiles) by imaging the wafer by infrared depolarization. An infrared depolarization parameter is generated for each epitaxial wafer. The parameters may be compared to determine which growth conditions are well-suited to produce substrates for epitaxial and/or post-epi heat treatments.
