  • Publication number: 20230238226
    Abstract: A semiconductor device manufacturing method comprising loading a substrate into a substrate treatment apparatus, performing a deposition process on the substrate, and cleaning the substrate treatment apparatus. The substrate treatment apparatus includes a housing defining a treatment area in which the deposition process is performed, a gas supply supplying a first process gas at a flow rate of 1000 sccm to 15000 sccm and supplying a second process gas, a remote plasma supply connected to the gas supply, generating a first process plasma and a second process plasma by applying RF power to plasma-process the first process gas and the second process gas, and a shower head installed in the housing to supply the first process plasma and the second process plasma to the treatment area. The second process plasma cleans a membrane material deposited on an inner wall of the housing.

  • Patent number: 9997566
    Abstract: Manufacturing an MRAM device may include forming an upper electrode on a magnetic tunnel junction stack, where the stack may include a lower electrode layer, a magnetic tunnel junction layer and a middle electrode layer that are sequentially formed on an insulating interlayer and a lower electrode contact on a substrate. The upper electrode may be formed on the middle electrode layer. An upper electrode protective structure may be formed to cover at least a sidewall and an upper surface of the upper electrode. The middle electrode layer, the magnetic tunnel junction layer and the lower electrode may be patterned by an etching process to form a middle electrode, a magnetic tunnel junction pattern and a lower electrode, respectively. The upper electrode protective structure may isolate the upper electrode from exposure during the patterning, and the upper electrode protective structure may remain on the upper electrode subsequently to the patterning.

  • Patent number: 8666064
    Abstract: An encryption/decryption method of an endecryptor including a plurality of endecryption units supporting an XES mode with tweak and ciphertext streaming (XTS) includes dividing an input data stream into consecutive data units; inputting the divided data units to the endecryption units, respectively; and simultaneously processing the input data units at the respective endecryption units. According to the encryption/decryption method, parallel processing is performed to encrypt/decrypt data at higher speed.

  • Patent number: 8439335
    Abstract: An air-damped engine mount has a filter module installed in a damping chamber formed by coupling between a main rubber and a main pipe. The air-damped engine mount may include a bolt, a main rubber into which the bolt is fitted and coupled, a hollow main pipe coupled with the main rubber and supporting the main rubber, a cover plate coupled with the main pipe to form a damping chamber between the cover plate and the main rubber, and a filter module coupled with the cover plate and configured to permit air to communicate through the filter module against flow resistance with the damping chamber and the outside, wherein the flow resistance against the air passing through the filter module regulates air pressure inside the damping chamber to reduce vibration in the main rubber.
