Patent number: 6677567Abstract: A scanning probe microscope uses two different scanners (also called “scanning stages”) that are completely detached each from the other, and are physically separated by a stationary frame. One scanner (called “x-y scanner”) scans a sample in a plane (also called “x-y plane”), while the other scanner (called “z scanner”) scans a probe tip (which is supported at a free end of a cantilever) in a direction (also called “z direction”) perpendicular to the plane. Detachment of the two scanners from one another eliminates crosstalk.Type: GrantFiled: February 15, 2002Date of Patent: January 13, 2004Assignee: PSIA CorporationInventors: Jaewan Hong, Joonhyung Kwon, Sang-il Park

Patent number: 6185991Abstract: A microscope uses electrostatic force modulation microscopy to measure mechanical and electrical characteristics of a sample. A tip contacts the sample while a voltage (which may have dc and ac components) is applied between the tip and sample. The tip oscillates even though the tip is contacting the sample due to strong electrostatic force interaction between the tip and sample. Different characteristics of the sample such as hardness, surface potential, capacitance, surface charge, and so forth, are measured by manipulating the oscillation of the tip relative to the sample and monitoring the position of the tip.Type: GrantFiled: February 17, 1998Date of Patent: February 13, 2001Assignee: PSIA CorporationInventors: Jaewan Hong, Sang-il Park, Zheong-Gu Khim
