The process begins with the cleaning and preparation of the silicon

wafer, which involves removing any impurities and creating a pristine

surface for subsequent processing. 该过程始于对硅晶片的清洁和准备，

包括去除任何杂质并为随后的加工创造一个原始的表面。This initial step is

crucial in ensuring that the DDPF process can proceed without any
