摘要:
Milling using a scanning probe microscope with a diamond tip removes a layer of material and produces a surface that is sufficiently smooth that it can be probed using a nanoprober to provide site-specific sample preparation and delayering. Diamond milling provides in situ, localized, precision delayering inside of a nanoprobing tool, thereby decreasing the turnaround time for integrated circuit analysis. Furthermore, unlike focused ion beam delayering, the diamond tip should not alter the electrical characteristics of the integrated circuit.

A tip array can include a tip substrate layer comprising a first surface and an oppositely disposed second surface, a plurality of tips fixed to the first surfaces, the tips comprising a tip end disposed opposite the first surface, a blocking layer coated on the first surface. The tip substrate layer is formed from a substrate material and the tips are formed from a tip material. The substrate material and the tip material each comprise an at least translucent material. The tips have a radius of curvature of less than about 1 μιη. The tips are substantially free from the blocking layer.

Devices for leveling an object for patterning a substrate surface, including an array of scanning probe tips, are provided. A device may include a support structure adapted to mount an object, the object having a plurality of protrusions adapted to form a pattern on a surface of a substrate upon contact of the object to the surface; and at least one flexible joint assembly mounted to the support structure and adapted to allow the object to achieve a parallel orientation with respect to the surface upon contact of the object to the surface. Also provided are apparatuses and kits incorporating the devices and methods of making and using the devices and apparatuses.
摘要:
Probe-based methods for patterning a surface of a material are described. In particular, high resolution patterning of molecules on a surface of a material, such as nano-scale patterns with feature sizes of less than 30 nanometers, are described. In one aspect, a method for patterning a surface of a material includes providing a material having a polymer film. A heated, nano-scale dimensioned probe is then used to desorb molecules upon interacting with the film. The film includes a network of molecules (such as molecular glasses) which are cross-linked via intermolecular (noncovalent) bonds, such as hydrogen bonds.

Better leveling procedures for patterning at the small scale including the nanoscale. A method comprising: providing at least one array of cantilevers comprising tips thereon, wherein the cantilevers comprise at least one relatively bright spot, or at least two relatively bright spots, near the tip upon viewing, providing a substrate, leveling the array and the substrate with respect to each other, wherein the relatively bright spot near the tip is viewed to determine a contact of the tip and substrate.
摘要:
Improved methods for loading arrays of tips with a material for subsequent deposition of the material from the tip to the substrate. Tip loading can be done by controlled vapor deposition which reduces the amount of non-specific material deposition onto a substrate. Improved nanoscale and microscale engineering and lithography can be achieved. Applications include better cellular studies including stem cell studies and stem cell differentiation control.
