Abstract: In accordance with some embodiments, a method includes placing a semiconductor wafer over a wafer stage; pressing a brush assembly against a backside surface of the semiconductor wafer, wherein the brush assembly comprises an inner brush member and an outer brush member laterally surrounding the inner brush member, and the outer brush member is made of a material having a lower rigidity than the inner brush member; rotating the brush assembly relative to the semiconductor wafer.

Abstract: A clip for securing one or more cables associated with a computing device includes a baseplate, a first wall, and a second wall. The first wall and the second wall extend from the baseplate. The first wall has a first inward projection at a distal end thereof. The second wall has a second inward projection at a distal end thereof. The first wall is generally parallel to the second wall. The first wall and the second wall are spaced apart from each other by an interior space configured to receive the one or more cables. The first inward projection and the second inward projection aid in preventing the one or more cables from moving outside of the interior space.

Abstract: An electrode structure of rechargeable battery includes a battery tab stack, an electrode lead, a welding protective layer and a welding seam. The battery tab stack is formed by extension of a plurality of electrode sheets. The electrode lead is joined to one side of the battery tab stack. The welding protective layer is joined to another side of the battery tab stack opposite to the electrode lead. The welding seam extends from the welding protective layer to the electrode lead through the battery tab stack.

Abstract: A collection bottle and a method for detecting a characteristic of a sample are provided. The collection bottle includes a body and a cover. The body of the collection bottle has an accommodating space. The cover of the collection bottle is removably assembled to the body of the collection bottle, and the cover includes a channel and a testing part. The channel of the collection bottle communicates the accommodating space and the outside environment. While the cover of the collection bottle is assembled to the body, the testing part extends toward the accommodating space.
