Abstract: An ammonium fluoride gas may be used to form a protection layer for one or more interlayer dielectric layers, one or more insulating caps, and/or one or more source/drain regions of a semiconductor device during a pre-clean etch process. The protection layer can be formed through an oversupply of nitrogen trifluoride during the pre-clean etch process. The oversupply of nitrogen trifluoride causes an increased formation of ammonium fluoride, which coats the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) with a thick protection layer. The protection layer protects the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) during the pre-clean process from being etched by fluorine ions formed during the pre-clean process.

Abstract: The disclosure relates to an extraction device for extracting soluble favors from raw materials that are distributed within liquid. The extraction device includes a first container, a second container, a valve, and an air suction device. The second container is configured for storing the mixture of the raw materials and the liquid. The valve is connected to the second container and the first container. The air suction device is connected to the first container and configured to decrease the internal pressure of the first container to a predetermined value. When the internal pressure of the first container reaches the predetermined value, the valve is activated to connect the first container to the second container. The disclosure also relates to an extracting method for using the extraction device.

Abstract: An optical touch apparatus including two touch panels, two optical sensing modules, and a rail device is provided. Each touch panel has two lateral sides separated from each other and a touch zone located between the two lateral sides. Each optical sensing module is disposed or near one lateral side of one of the touch panels. The rail device is coupled to the two touch panels, such that two touch panels can slide in parallel along a predetermined direction and can be selectively operated in one of a first touching mode and a second touching mode, and the optical touch apparatus can flexibly change its size of touch zone.

Abstract: An optical touch panel device is adapted to be operable with a stylus. The stylus has a touch portion and a light-emitting portion that is connected to the touch portion and that emits light when the touch portion is touched. The optical touch panel device includes a back housing having an opening, a transparent panel sealing the opening of the back housing, at least two optical sensors disposed in the back housing and adapted to sense the light from the light-emitting portion of the stylus, and a processing module coupled to the optical sensors for determining a position on the transparent panel at which the touch portion of the stylus touches based on the light detected by the optical sensors.
