Get PriceFoundries are the primary end-user of the semiconductor fabrication market due to the steady adoption of fabless business model. The market will witness increasing demand for devices such as memory, logic, discrete, analog, sensor, and opto devices.
Get PriceThe grinding process referred in this paper is the vertical spindle surface grinding (a.k.a. wafer grinding) using a cup wheel. A typical cup wheel is illustrated in Fig. 1. Fig. 2 illustrates the wafer grinding process. During grinding, the grinding wheel and the wafer rotate about their own rotation axes simultaneously, and the wheel is fed towards the wafer along its axis.
