Methods, devices, equipment and media for adjusting grinding time in chemical mechanical polishing equipment

ActiveCN115972074BRealize fine adjustmentHigh precisionLapping machines
This invention provides a method, apparatus, equipment, and medium for adjusting the grinding time of a chemical mechanical polishing (CMP) device. The method involves obtaining the target grinding thickness of the current wafer to be ground; starting the timer after grinding the wafer using the target CMP device; monitoring the grinding pressure during the grinding process; and calculating the current total grinding thickness based on a first relationship between the removal rate and the grinding pressure, along with the monitored grinding pressure. When the current total grinding thickness reaches the target grinding thickness, grinding and timing are terminated, yielding the current grinding time. The method then calculates the actual removal rate and the theoretical removal rate, and updates the first relationship using the difference between the two rates. This updated first relationship is then used to adjust the grinding time for the next wafer to be ground. This achieves dynamic adjustment of the grinding time during batch wafer grinding, improving the accuracy of wafer grinding and further enhancing the quality of the ground wafer products.
