Such a fluid can be liquid or gas or a mixture thereof. Mixtures of liquid or gas comprise fluids having gas as the continuous phase and liquid as the disperse phase (e.g. aerosols) and fluids having liquid as the continuous phase and gas as the disperse phase (e.g. carbonated water). The invention further relates to a device and a method for wet treating a flat disc-like substrate, such as semiconductor wafers, flat panel displays or compact discs utilizing such a fluid discharging device. If in the following the term wafer is used, such disk-like substrates are meant.

A supporting shelf for compact disks includes at least a first tubular housing and a second tubular housing and each has a different inner diameter but a similar cross section. The second tubular housing that has a small inner diameter is disposed within the first tubular housing. Each of the first and second tubular housings has its opening directed upward for readily engagement therebetween. Each of the tubular housings is provided with a plurality of retaining slots at the outer wall and that are parallel to each other, wherein a CD can be readily inserted and retained by the retaining slots of the housings. When a plurality of first and second tubular housings are engaged with each other, a tower-shape supporting shelf can be configured. Each of the receiving slots can be directed upward and angularly. The engagement between the first and second tubular housing can be facilitated through retaining holes and pin-shaft or retaining ball and recess.

A printable sheet including one or more envelope assemblies formed thereon, each having a central body panel, an end flap, a pair of opposing top and bottom panels, a business card removably attached and incorporated into the bottom panel, and a retaining flap. The sheet is capable of being placed in a printer to have images and/or indicia printed on the envelope assemblies. Each envelope assembly is capable can be removed from the printable sheet and folded along weakened lines, and adhered to itself to form a secure sleeve or envelope for holding various items. Each envelope has a retaining flap on the open end that can be tucked into the envelope after insertion of its contents in order to retain the contents, which could either be used or removed if desired. The envelope could be designed to readily hold business card compact discs. The business card can be subsequently separated by the user from the formed envelope.

The invention provides a method for manufacturing the structure of a semiconductor device for forming the structure of a dual damascene, which comprises the steps of: providing a front-end device structure; sequentially forming a first metal layer, an etching stopping layer, a second metal layer and a first photoresist layer provided with a first opening pattern on the surface of an intermetallic dielectric layer; firstly etching till that the surface of the etching stopping layer is exposed; removing the first photoresist layer; forming a bottom anti-reflection layer; forming a second photoresist layer with a second opening pattern, wherein the second opening pattern is arranged right above an opening in the second metal layer; secondarily etching till that the surface of the intermetallic dielectric layer is exposed; removing the second photoresist layer and the bottom anti-reflection layer; and thirdly etching till that the surface of the front-end device structure is exposed. Due to the adoption of the method, the bottom anti-reflection coat (BARC)-filling quality can be improved, and the bad influence to a compact disc (CD) caused by overlong BARC etch back time can be avoided.

A downhole oil-water separation device with multistage hydrocyclones in parallel is applicable to a downhole oil-water separation system of a Y-shaped tubular column structure.
