Patent number: 8677931Abstract: A pattern having exceptionally small features is printed on a partially fabricated integrated circuit during integrated circuit fabrication. The pattern is printed using an array of probes, each probe having: 1) a photocatalytic nanodot at its tip; and 2) an individually controlled light source. The surface of the partially fabricated integrated circuit comprises a photochemically active species. The active species undergoes a chemical change when contacted by the nanodot, when the nanodot is illuminated by light. To print a pattern, each probe raster-scans its associated nanodot across the surface of the partially fabricated integrated circuit. When the nanodot reaches a desired location, the nanodot is illuminated by the light source, catalyzing a change in the reactive species and, thus, printing at that location. Subsequently, reacted or unreacted species are selectively removed, thereby forming a mask pattern over the partially fabricated integrated circuit.Type: GrantFiled: August 28, 2009Date of Patent: March 25, 2014Assignee: Micron Technology, Inc.Inventor: Gurtej S.

Patent number: 7322723Abstract: An illumination device has an illumination means formed by an arrangement of a plurality of semiconductor light sources (2) grouped together to form a field. Sensor elements (3) are arranged at individual positions of the field instead of the semiconductor sources (2). A multifunctional headlight can thus be advantageously created. The headlight can be embodied as a robust, compact, low-space unit. By virtue of the fact that the light sources (2) and the sensor elements (3) do not necessarily use the same lens system (1) i.e. each individual element of the multifunctional headlight can be provided with an individually designed lens system (1), the beam path of the illumination device can be separated from the field of vision of the sensor system and can thus be determined independently over large areas.Type: GrantFiled: December 9, 2003Date of Patent: January 29, 2008Assignee: DaimlerChrysler AGInventors: Manfred Griesinger, Markus Hartlieb, Wilhelm Kinces, Hans-Georg Leis, Siegfried Rothe

Patent number: 7175712Abstract: A UV curing apparatus and method is provided for enhancing the distribution and application of UV light to UV photo initiators in a UV curable ink, coating or adhesive. The UV curing apparatus and method comprises UV LED assemblies in a first row with the UV LED assemblies spaced from adjacent UV LED assemblies. At least one second row of a plurality of UV LED assemblies are provided next to the first row but with the UV LED assemblies of the second row positioned adjacent the spaces between adjacent UV LED assemblies in the first row thereby to stagger the second row of UV LED assemblies from the UV LED assemblies in the first row. Desirably, the rows of staggered UV LED assemblies are mounted on a panel. UV curable products, articles or other objects containing UV photo initiators that are in or on a web can be conveyed or otherwise moved past the rows of UV LED assemblies for effective UV curing.Type: GrantFiled: January 9, 2003Date of Patent: February 13, 2007Assignee: Con-Trol-Cure, Inc.Inventor: Stephen B.

Patent number: 7161585Abstract: There is described a method of post-processing and reporting detected displacement in an optical pointing device as well as a sensing device for an optical pointing device implementing this method. Displacement is detected and a first count representative of a magnitude of the detected displacement is accumulated in an associated accumulation unit, this first count representing the magnitude of the detected displacement at a first resolution (or detection resolution). The first count accumulated in the accumulation unit is processed to convert this first count into a report count representing the magnitude of the detected displacement at a second resolution (or reporting resolution) lower than the first resolution. This report count is then reported, for instance to a PC or an external controller. These operations are repeated to generate periodic motion reports at the second resolution.Type: GrantFiled: July 1, 2003Date of Patent: January 9, 2007Assignee: EM Microelectronic-Marin SAInventors: James Harold Lauffenburger, Gil Afriat, Robert R.
