Description

technical field [0001] The invention relates to the technical field of processing nanoscale structures and devices, in particular to a nanoimprinting machine and a pressurizing method thereof. Background technique [0002] "Nanoimprinting" is a new method of nano-pattern replication. In nanoimprinting, the imprinting mold is the template for nanoimprinting. The size of the convex-concave structure is on the order of nanometers. The nanostructures are shaped by methods such as cooling or ultraviolet exposure, after which the template is removed, and the nanostructures are transferred to the semiconductor silicon wafer by other processes. This process is called nanoimprinting. The difficulty of nanoimprinting technology lies in providing nanoscale flattening devices, and the most reasonable driving method and operability. At present, traditional nanoimprinting machines generally have uneven pressure distribution and can only perform one form of solidification. The disadvant...
