A system for nano-imprint with mold deformation detector is disclosed for real-time monitoring of the deformation of the mold. An electrostatic plate capacitor is embedded in the mold, serving as the deformation detector. The capacitor includes two opposite metal film electrodes formed by silicon micromachining technique on opposite surfaces of the mold and connected by a metal lead. During imprinting, the mold is acted upon by an external force and deformation occurs, which induces change of distance between the metal film electrodes and thus variation of the capacitance of the capacitor. The amount of deformation of the mold can then be assessed by comparing the capacitance with a reference. Thus, real-time detection and monitoring of the deformation of the nano-imprint mold is realized. Also disclosed is a method for carrying out the real-time monitoring of the deformation of the mold.

Nano-imprint system with mold deformation detector and method of monitoring the same

The present invention provides a method for in-situ real-time monitoring of mold deformation by using a database to store temporary information during the following steps: (a) providing a mark on the mold body that is easy to observe in order to monitor the mold deformation, (b) installing a signal source and a monitor device for monitoring the deformation quantity on the mold, (c) transforming the above deformation quantity into computer signals for storing in the database and (d) issuing controlling or warning signals to the imprinting machine based on the processing results of the stored information in the database.
