摘要:
Provided is a method of fabricating a nanoimprint mold which can form sub-100 nm fine pattern structures. The method includes forming patterns on a first substrate using an E-beam lithography (EBL) process, and transferring the patterns formed on the first substrate to a second substrate using a nanoimprint lithography (NIL) process to complete an NIL mold. Accordingly, the method can easily fabricate the nanoimprint mold at low costs on a quartz or glass substrate, which is not suitable for an EBL process to produce sub-100 nm patterns, by utilizing the advantages of the EBL process with a resolution of tens of nanometers.

An electrostatic discharge protection circuit protects the internal circuits of a semiconductor. The electrostatic discharge protection circuit includes a first electrostatic protection unit connected to a power source supply pad. The first electrostatic protection unit discharges an ESD current into the power source supply pad when an ESD is introduced into the input/output pad, and generates a first driving voltage by utilizing the ESD current flow through a voltage-drop unit. A driver driven by the first driving voltage generates a second driving voltage by an ESD current. A second electrostatic protection unit discharges the introduced ESD current into the power source supply pad by the second driving voltage such that a voltage applied to a gate of the first NMOS transistor is reduced.
