Inventors:

Byung Kwon Kim - Shiheung City, KR
Han T. Cho - Franklin Lakes NJ, US

International Classification:

A47L 15/06

US Classification:

134 953

Abstract:

A dish washer for commercial use is provided. The dishwasher according to current application is used for restaurants, hospital, school and military camp, etc. The dish washer of the current application has an auxiliary rinsing water pipe that is embedded inside of a washing water pipe. The rinsing water supplied to the washing water pipe drives the remaining soapy washing water out of an upper washing water impellor just after the washing step is finished. In rinsing step, rinsing water is supplied to an upper rinsing impellor via main rinsing water pipe. Rinsing water is sprayed to the bottom of the washing water impellor to remove the residual soapy washing water droplets. The dish washer of the current application removes a chance of contamination of dishes and cups by soapy washing water drops after washing is finished.

International Classification:

B08B 7/00

US Classification:

134 11, 134 30

Abstract:

Embodiments of the disclosure generally relate to methods of removing etch by-products from the plasma processing chamber using carbon monoxide or carbon dioxide. In one embodiment, a method for dry cleaning a processing chamber includes exposing a chamber component disposed within the processing chamber in absence of a substrate disposed therein to a first cleaning gas mixture comprising carbon monoxide or carbon dioxide, wherein a portion of the chamber component has a film layer or residues deposited thereon, and the film layer or residues comprises a refractory metal and/or a metal silicide.

International Classification:

H01L 21/762

US Classification:

438404

Abstract:

Embodiments of the present invention provide methods to etching a recess channel in a semiconductor substrate, for example, a silicon containing material. In one embodiment, a method of forming a recess structure in a semiconductor substrate includes transferring a silicon substrate into a processing chamber having a patterned photoresist layer disposed thereon exposing a portion of the substrate, providing an etching gas mixture including a halogen containing gas and a Clgas into the processing chamber, supplying a RF source power to form a plasma from the etching gas mixture, supplying a pulsed RF bias power in the etching gas mixture, and etching the portion of the silicon substrate exposed through the patterned photoresist layer in the presence of the plasma.

US Classification:

438719, 438710

Abstract:

In some embodiments, a method of forming a three dimensional NAND structure atop a substrate may include providing to a process chamber a substrate having alternating nitride layers and oxide layers or alternating polycrystalline silicon layers and oxide layers formed atop the substrate and a photoresist layer formed atop the alternating layers; etching the photoresist layer to expose at least a portion of the alternating nitride layers and oxide layers or alternating polycrystalline silicon layers and oxide layers; providing a process gas comprising sulfur hexafluoride (SF), carbon tetrafluoride (CF), and oxygen (O) to the process chamber; providing an RF power of about 4 kW to about 6 kW to an RF coil to ignite the process gas to form a plasma; and etching through a desired number of the alternating layers to form a feature of a NAND structure.
