Patent number: 9389244Abstract: A scanning probe assembly having a nanometer sensor element defined at a tip apex and its method of fabrication using micro-electromechanical systems (MEMS) processing techniques. The assembly comprises a probe body, a cantilever extending outward, and a hollow tip at the end of the cantilever. A first conductive material is disposed on the hollow tip, followed by a dielectric layer thus embedding the conductive layer. A nanometer hole is milled through the tip, first conductor and dielectric materials. A metal sensor element is deposited by means of electrochemical deposition in the through-hole. A second conductor is deposited on a lower layer. The first and second conductors form electrical connections to the sensor element in the tip. The intra-tip metal, in combination with other layers, may form a thermocouple, thermistor, Schottky diode, ultramicroelectrode, or Hall Effect sensor, and used as a precursor to grow spikes such a nanotubes.Type: GrantFiled: May 6, 2014Date of Patent: July 12, 2016Assignee: Applied Nanostructures, Inc.Inventors: Jeremy J. Goeckeritz, Gary D. Aden, Ami Chand, Josiah F. Willard

Patent number: 8828243Abstract: A cantilever-tip assembly for atomic force microscopy (AFM) or other scanning probe microscopy and its method of making based on micro-electromechanical systems (MEMS). Two crystalline silicon wafers and attached oxide and nitride layers are bonded together across an intermediate dielectric layer. A thin cantilever with a tetrahedral silicon probe tip at its distal end are formed in one wafer by anisotropic etching of silicon and a support structure is formed in the other wafer to support the proximal end of the cantilever preferably having an inclined face formed by anisotropic silicon etching. The cantilever may be silicon or silicon nitride.Type: GrantFiled: September 2, 2010Date of Patent: September 9, 2014Assignee: Applied Nanostructures, Inc.Inventors: Rakesh Poddar, Ami Chand

Patent number: 8397555Abstract: The present invention is directed to scanning probes in which a cantilever contacts a stylus via an integrated stylus base pad, and methods for fabricating such probes. The probe offer many advantages over other types of scanning probes with respect to eliminating the need for a soft, reflective coating in some applications and providing for the simple fabrication of sharp stylus tips, flexibility with respect to functionalizing the tip, and minimal thermal drift due to reduced bimorph effect. The advantage of these features facilitates the acquisition of high resolution images of samples in general, and particularly in liquids.Type: GrantFiled: February 28, 2011Date of Patent: March 19, 2013Assignee: Applied NanoStructures, Inc.Inventor: Ami Chand
