摘要:
A method (and resultant structure) of forming a plurality of masks, includes creating a reference template, using imprint lithography to print at least one reference template alignment mark on all of a plurality of mask blanks for a given chip set, and printing sub-patterns on each of the plurality of mask blanks, and aligning the sub-patterns to the at least one reference template alignment mark.
摘要:
An apparatus (and method) for forming a pattern on a workpiece, includes an optical phase contrast image sensor, and an imprint lithography system coupled to the optical phase contrast image sensor for laterally aligning an imprint template feature relative to the workpiece.
摘要:
A method (and apparatus) for nano lithography, includes applying a pneumatic pressure to at least one of a surface of a semi-rigid mask or template and a portion of a surface of a resist-coated workpiece, and, by the applying of the pneumatic pressure, transferring a pattern from the mask to the workpiece.
摘要:
An apparatus (and method) for referencing a surface of a workpiece during imprint lithography, includes an air bearing for mechanically referencing a surface of the workpiece, and a lithographic template coupled to the air bearing.
摘要:
An optical probe (and method) for measuring a surface in an environment containing a first substance, includes a light source for transmitting a light onto an area of the surface to obtain a measurement, a source of the first substance including one of a fluid and a gas for displacing a second substance from an area of the surface receiving the light, and a measuring device for receiving the light being reflected from the surface and for determining a measurement of the surface based upon the reflected light.
