Abstract:
1. An imprinting apparatus, comprising: a plate unit; and a plurality of imprinting modules provided on a lower surface of the plate unit so that each of the plurality of imprinting modules is self-aligned by a compliance of six degrees of freedom, and is vertically moved along with the plate unit by a controller, wherein each of the imprinting modules is independently self-aligned in response to surface conditions of an objective material to compensate for a relative pose error of each of the imprinting modules with respect to the objective material, so that a pattern formed on a lower end of each of the plurality of imprinting modules is imprinted on an upper surface of the objective material within a predetermined unit range, and a sequence of imprinting the patterns of the plurality of imprinting modules on the objective material is variously controlled.
