An apparatus to control displacement of a body spaced-apart from a surface includes a flexure system having a first flexure member defining a first axis of rotation and a second flexure member defining a second axis of rotation. A body is coupled to the flexure system to move about a plurality of axes. An actuation system is coupled to the flexure system to selectively constrain movement of the body along a subset of the plurality of axes.

The present invention is directed to a compliant device comprising a support body, a floating body, and a plurality of flexure arms. Each of the plurality of flexure arms is connected between the support body and the floating body to transfer a load therebetween in parallel. To that end, the flexure arms have first and second sets of flexure joints. The first set of flexure joints facilitate rotational movement of said flexure arm about a first axis extending along a first direction. The second set of flexure joints are arranged to facilitate rotational movement of the flexure arm about a second axis, extending along a second direction that is transverse to the first direction. The flexure joints are revolute joints.

The present invention is directed towards a method for determining deformation parameters that a patterned device would undergo to minimize dimensional variations between a recorded pattern thereon and a reference pattern, the method including, inter alia, comparing spatial variation between features of the recorded pattern with respect to corresponding features of the reference pattern; and determining deformation forces to apply to the patterned device to attenuate the dimensional variations, with the forces having predetermined constraints, wherein a summation of a magnitude of the forces is substantially zero and a summation of moment of the forces is substantially zero.

The present invention is directed towards a method and system of controlling movement of a body coupled to an actuation system that features translating movement of the body in a plane extending by imparting angular motion in the actuation system with respect to two spaced-apart axes. Specifically, rotational motion is generated in two spaced-apart planes, one of which extends parallel to the plane in which the body translates. This facilitates proper orientation of the body with respect to a surface spaced-apart therefrom.

The present invention is directed to providing a method and system to measure characteristics of a film disposed on a substrate. The method includes identifying a plurality of processing regions on the film; measuring characteristics of a subset of the plurality of processing regions, defining measured characteristics; determining a variation of one of the measured characteristics; and associating a cause of the variations based upon a comparison of the one of the measured characteristics to measured characteristics associated with the remaining processing regions of the subset. The system carries out the aforementioned method.

The present invention is directed to a method forming conductive templates that includes providing a substrate; forming a mesa on the substrate; and forming a plurality of recessions and projections on the mesa with a nadir of the recessions comprising electrically conductive material and the projections comprising electrically insulative material. It is desired that the mesa be substantially transparent to a predetermined wavelength of radiation, for example ultraviolet radiation. As a result, it is desired to form the electrically conductive material from a material that allows ultraviolet radiation to propagate therethrough. In the present invention indium tin oxide is a suitable material from which to form the electrical conductive material.

The present invention is directed toward a system to vary dimensions of a substrate, such as a template having a patterned mold. To that end, the system includes a substrate chuck adapted to position the substrate in a region; a pliant member; and an actuator sub-assembly elastically coupled to the substrate chuck through the pliant member. The actuator assembly includes a plurality of lever sub-assemblies, one of which includes a body lying in the region and spaced-apart from an opposing body associated with one of the remaining lever sub-assemblies of the plurality of lever sub-assemblies. One of the plurality of lever assemblies is adapted to vary a distance between the body and the opposing body. In this manner, compressive forces may be applied to the template to remove unwanted magnification or other distortions in the pattern on the mold. The pliant member is configured to attenuate a magnitude of resulting forces sensed by the substrate chuck generated in response to the compressive forces.
