20090023607 | COMPACT NANOFABRICATION APPARATUS - An apparatus for use in fabricating structures and depositing materials from tips to surfaces for patterning in direct-write mode, providing ability to travel macroscopic distances and yet provide for nanoscale patterning. Useful in small scale fabrication and nanolithography. The instrument can be compact and used on a laboratory bench or desktop. An apparatus comprising: at least one multi-axis assembly comprising a plurality of nanopositioning stages, at least one pen assembly, wherein the pen assembly and the multi-axis assembly are adapted for delivery of material from the pen assembly to a substrate which is positioned by the multi-axis assembly, at least one viewing assembly, at least one controller. Nanopositioning by piezoelectric methods and devices and motors is particularly useful. The apparatus can include integrated environmental chambers and housings, as well as ink reservoirs for materials to be delivered. The viewing assembly can be a microscope with a long working distance. Particularly useful for fabrication of bioarrays or microarrays. The multi-axis assembly can be a five-axis assembly. Software can facilitate efficient usage. | 01-22-2009 |
20090178165 | CANTILEVER WITH PIVOTING ACTUATION - Improved actuation device useful in direct-write nanolithography and imaging including use of a pivot point for downward deflection of a cantilever with long travel path. A device comprising at least one holder, at least one cantilever, an extension of the said cantilever wherein the extension is integrated with an actuator, wherein the cantilever is adapted for actuated movement. The actuator can be electrostatic, thermal, or piezoelectric. The cantilever can comprise a tip, and material can be transferred from the tip to a surface. | 07-09-2009 |
20100147820 | HEATED CANTILEVER - A device is provided comprising at least one cantilever comprising at least one tip and at least one heating element. Methods for making and using such a device are also provided. | 06-17-2010 |
20100235954 | DUAL-TIP CANTILEVER - A device comprising at least one cantilever comprising at least two tips is described, where the tips have substantially the same tip heights. Methods for making and using such a device are also provided. The height of one tip off of the surface can be more easily determined when the two tips have equal height. | 09-16-2010 |
20100294146 | Stamps with micrometer-and nanometer-scale features and methods of fabrication thereof - Stamps and methods of making stamps for applications in anti-counterfeiting and authentication. The stamps are relatively small in size and feature nanoscale and microscale identification regions and features. High throughput manufacturing and high resolution methods are used to make the stamps including electron beam lithography and optical lithography. Anti-fouling coatings can be applied. | 11-25-2010 |
20100294844 | Identification features - Methods for providing pharmaceutical compositions and objects with identification regions and identification features which are difficult to detect. Microlithography, nanolithography, and stamping methods are used. The identification features can be positive protrusions or negative indentations with respect to the surface. The identification regions can comprise bar codes and holograms. DPN printing or other lithographies such as electron beam lithography, optical lithography, or nanoimprint lithography can be used to prepare stamps, which are then used to prepare the identification features. Redundant patterns can be formed. The invention is useful for counterfeit prevention. An apparatus for stamping the identification features is also described. | 11-25-2010 |
