超聲橢圓振動輔助拋光硅片表面形貌與材料去除仿真
[Abstract]:As the main component of electronic products, the processing quality of single crystal silicon wafer, the main substrate material of integrated circuit (Integrate Circuit), affects the performance of electronic products to a certain extent. At present, as the performance of electronic products is getting better and better, the integration of IC is also put forward, which requires the etched linewidth of silicon wafer to be thinner and the surface flatness higher and higher. In order to reduce the manufacturing cost of silicon wafer and increase the output of silicon wafer, the diameter of silicon wafer is getting larger and larger. On the contrary, electronic products require the development of chips in the direction of miniaturization and thinning, which brings many problems to be solved urgently for silicon wafer processing, especially polishing. Therefore, it is particularly prominent to explore a machining method to improve the surface quality and material removal efficiency of single crystal silicon wafer. Ultrasonic vibration aided machining has been widely used because of its low polishing force, high material removal rate and small surface damage. In view of this, on the basis of the traditional chemical mechanical polishing method of consolidated abrasive particles, ultrasonic elliptical vibration aided machining technology is introduced, and the machining experiment and simulation analysis are carried out. The main contents are as follows: firstly, the polishing technology of silicon wafer and the principle and principle of ultrasonic aided machining are summarized, and the elliptical vibration trajectory of machining tool in ultrasonic machining is simulated. Secondly, the main components and working principle of ultrasonic elliptical vibration assisted polishing device are introduced. On this basis, the mathematical models of the surface morphology, the polishing surface morphology and the material removal of the consolidated abrasive polishing wafer are established respectively. The surface morphology and material removal effect of ultrasonic vibration assisted polishing and traditional polishing silicon wafer are compared and analyzed by MATLAB software. It is concluded that the surface quality of ultrasonic elliptical vibration assisted polishing silicon wafer is better and the material removal rate is higher. Finally, the effect of polishing pressure on the surface quality and material removal efficiency of ultrasonic elliptical vibration assisted polishing silicon wafer was studied, and some theories and technological laws were obtained. Through simulation and experimental research, it provides a certain theory for improving the polishing surface quality and material removal effect of silicon wafer in practical machining.
