For the reproducing unit of nano-imprinting composite templateTechnical field
The present invention relates to the template duplicating device in a kind of micro-nano technology field, be specifically related to a kind of reproducing unit for nano-imprinting composite template.
Background technology
In large scale integrated circuit manufactures, most widely used is photoetching process, which includes gold-tinted photoetching, extreme ultraviolet photolithographic, electron-beam direct writing, immersion lithography etc.Under Moore's Law is guided, large scale integrated circuit enters nanometer era steadily, and photoetching forms bottleneck at 45nm node.Due to the restriction that optical lithography techniques is intrinsic, be difficult to meet semiconductor industry and continued along Moore's Law fast-developing.In Graphic transitions technology of future generation, electron-beam direct writing, X-ray exposure and nanometer embossing occupy critical role.Wherein nanometer embossing takes the lead in being proposed by professor StephenY.Chou, and technology has that output is high, cost is low and the simple advantage of technique.This is the brand-new Graphic transitions technology of a kind of difference and conventional lithographic techniques.Nanometer embossing had both had the advantage of the necessary high yield of large-scale industrial production, low cost, had possessed the high resolving power that the technology such as electron-beam direct writing just can reach simultaneously.Its appearance and fast development cause rapidly the extensive attention of whole world research and production department.
In recent years, nanometer embossing obtains swift and violent development, and in wherein impressing, template is prepared in order to gordian technique.Template uses direct electronic beam writing technology to prepare usually, but electron-beam direct writing speed is slow, and cost is high.The preparation of template becomes the key link in nanometer embossing always.Therefore, find a kind of low cost of manufacture, to copy fast and the method preparing template copying flatness high is particularly important.
Summary of the invention
