Abstract:
Silicon (Si) wafers are the most commonly used substrates of semiconductor devices. The device design rule is miniaturization, and the device chip size is being increased to improve device integration, requiring that Si wafers be manufactured with higher flatness and larger diameters. The polishing used as a finishing process of Si wafers, however, has a serious problem; it is very difficult to set the appropriate conditions for polishing the Si wafer while wearing the polishing pad stably to high flatness. In our previous work, a method of optimizing polishing conditions based on kinematical

Abstract:
The primary consumables in chemical mechanical polishing (CMP) are the polishing pad and slurry. The polishing pad significantly influences the stability of the polishing process and the cost of consumables (CoC). Usually a diamond pad conditioner is used to scrap off the polishing debris from the pad top. Recently, an alternative planarization process can be achieved by polishing with a "fixed abrasive pad" (FAP). In order to dress bumps on FAP, this paper use an amorphous diamond, a diamond-like carbon deposited by cathode arc system as the dresser for FAP. The amorphous diamond can produce

Abstract:
The polishing pad plays a significant role in the Chemical Mechanical Polishing (CMP) process and its wear influences the surface accuracy of the polished wafer. A new polishing pad wear model is introduced and the law of pad wear along the pad radius is discussed, thus a new FAP with optimized pattern is designed and prepared in order. The flatness of the wafer lapped with a uniform pattern pad and that with an optimized pattern was compared. Results show that the PV value of the latter is lower that of the former.

Abstract:
Polishing process is a primary technique for planarization of material surface in manufacture fabrication. The pad structure and its material properties are important to determine the polish rate and planarity that can be achieved by the polishing process. Besides, the pad conditioning is used to regenerate the surface of the polishing pad surface by breaking up the glazed areas. Because the polishing and pad conditioning mechanism is inadequately understood and because higher levels of pad polishing performance are desired, the investigation of experiment becomes more important.In this paper,

Chemical mechanical polishing is used to manufacture silicon wafers as the final material removal process to meet the ever-increasing demand for flatter wafers and lower prices. The polishing pad is one of the critical factors in planarizing wafer surfaces and its properties play critical roles in polishing. However, pad properties change during the process.
