摘要:
A method for removing polishing byproducts and a polishing device are provided. The method includes mounting a positive electrode on the center of a polishing platen and a negative electrode on an edge of the polishing platen, applying a voltage between the positive electrode and the negative electrode after a polishing process for metal is finished, and rotating the polishing platen and rinsing a polishing pad with deionized water or a chemical cleaning solution to remove polishing byproducts that are formed in the polishing process. The combination of the centrifugal force and the electromotive force increases the removal rate of the polishing byproducts.

The present invention discloses a method for fabricating semiconductor devices. After removing excessive aluminum to form aluminum gates through a chemical mechanical planarization (CMP) process, the exposed surfaces of the aluminum gates are oxidized with H2O2 solution to form a film of alumina, and the semiconductor device is cleaned.

摘要:
A semiconductor device and a method for manufacturing the semiconductor device are provided. The semiconductor device uses an aluminum alloy, rather than aluminum, for a metal gate. Therefore, the surface of the high-k metal gate after the CMP is aluminum alloy rather than pure aluminum, which can greatly reduce defects, such as corrosion, pits and damage, in the metal gate and improve reliability of the semiconductor device.
摘要:
A polishing method is disclosed, which includes: conditioning a polishing pad, after polishing metal material of a previous wafer; spraying organic acid solution to the polishing pad; spraying deionized water to the polishing pad; performing a water-removing treatment on the polishing pad; and spraying polishing liquid to the polishing pad and polishing metal material of a next wafer. The method can prevent scratches on the surface of metal material of wafers and improve yield rate.

A gutter-cleaning tool set consists of a lightweight, adjustable or fixed length pole, a gutter-shaped blade, a gutter-shaped brush, a metal pin to lock the blade or brush on the end of the pole and a nylon string to secure the pin to the holding pole, the tool set is designed to collect deposits such as fallen leaves and roof debris in the gutters and to brush the rain gutter for thorough cleaning.
摘要:
New photoresist compositions are provided that comprise one or more materials that have base-reactive groups and are particularly useful for dry lithography. Particularly preferred photoresists of the invention can exhibit reduced defects following development of a coating layer of the resist.
摘要:
A method for cleaning a polishing pad includes dispensing a first amount of deionized water on the polishing pad; cleaning the polishing pad with an acidity/alkalinity solution after dispensing the first amount of deionized water on the polishing pad; rinsing the polishing pad with a second amount of deionized water after cleaning the polishing pad with the acidity/alkalinity solution; removing the acidity/alkalinity solution from the polishing pad. In a subsequent CMP process, the method includes polishing a GST material device for obtaining an improved performance of the GST material device.
