Abstract: Impurities in a liquefied solid fuel utilized in a droplet generator of an extreme ultraviolet photolithography system are removed from vessels containing the liquefied solid fuel. Removal of the impurities increases the stability and predictability of droplet formation which positively impacts wafer yield and droplet generator lifetime.

Abstract: An emotion perceiving artificial intelligence mask includes a processing circuit, a sensing circuit and a display circuit. The processing circuit includes a display control module and an artificial intelligence calculation module. The sensing circuit receives an emotion perceiving message and transmits the emotion perceiving message to the artificial intelligence calculation module. The artificial intelligence calculation module calculates and analyzes the emotion perceiving message to generate a multidimensional emotion perceiving index factor and transmit the multidimensional emotion perceiving index factor to the display control module. The display control module generates a dynamic display picture message according to the multidimensional emotion perceiving index factor. The display circuit receives the dynamic display picture message transmitted by the display control module and relatively displays an emotion perceiving dynamic picture.

Abstract: A container has a body, two handles, a handle combination structure, and one lid. The body has a body space forming in the body. The handles are connected with the body, and each handle has two connecting portions and two folding grooves. The connecting portions are formed between the handle and the body and are bendable. The handle combination structure is formed on the handles to selectively combine the two handles with each other. The lid is connected with the body and has a connecting portion formed between the body and the lid and being bendable. The body and the lid are respectively located in spaces which are respectively formed between the body and the handles.
