摘要:
A brewing device for either coffee or tea have a water pot bottomed with a base accomodating a heating element and a temperature-sensitive switch connected electrically therewith, by which applying heat to the water pot when being energized and cutting off the source of power at predetermined temperature, and a receiver for coffee grinds or tea to be brewed being disposed by the side of the pot. A U-shaped tube provided between the pot and the receiver having a first leg extended through an first aperture provided in the first lid and a second leg extended through a second aperture provided in the second lid, the former is gas tight sealed with the wall defining the first aperture but on the contrary, there is sufficient opening left between the receiver and the wall defining the second aperture. By such arrangement the water contained in the pot will rise in the first leg till reaching the top of the tube and then descend in the second leg to the receiver by the vapor pressure exerted on the water surface during heating until the water in the pot is exhausted, after de-energized, the brewed beverage in the receiver will return through the bridging means to the pot due to the atmospheric pressure.
摘要:
A method for forming a hard mask for gate electrode patterning in a semiconductor device is disclosed. The method includes providing a polysilicon layer to be etched and forming over the polysilicon layer, a nitride hardmask with a relatively high etch rate to hydrofluoric acid, as compared to the etch rate of silicon oxide. The polysilicon can then be patterned using the hardmask and the hardmask can be removed using hydrofluoric acid.
