Patent number: 8067305Abstract: Provided are methods for forming an electrically conductive structure of a desired three-dimensional shape on a substantially planar surface of a substrate, e.g., a semiconductor wafer. Typically, the particulate matter is deposited in a layer-by-layer manner and adhered to selected regions on the substrate surface. The particulate matter may be deposited to produce a mold for forming the structure and/or to produce the structure itself. A three-dimensional printer with associated electronic data may be used without the need of a lithographic mask or reticle.Type: GrantFiled: September 3, 2008Date of Patent: November 29, 2011Assignee: Ultratech, Inc.Inventors: Arthur W. Zafiropoulo, Andrew M. Hawryluk

Publication number: 20110089523Abstract: Provided are systems and processes for forming a three-dimensional circuit on a substrate. A radiation source produces a beam that is directed at a substrate having an isolating layer interposed between circuit layers. The circuit layers communicate with reach other via a seed region exhibiting a crystalline surface. At least one circuit layer has an initial microstructure that exhibits electronic properties unsuitable for forming circuit features therein. After being controllably heat treated, the initial microstructure of the circuit layer having unsuitable properties is transformed into one that exhibits electronic properties suitable for forming circuit feature therein. Also provided are three-dimensional circuit structures optionally formed by the inventive systems and/or processes.Type: ApplicationFiled: December 21, 2010Publication date: April 21, 2011Applicant: ULTRATECH, INC.Inventors: Arthur W.

Publication number: 20100084744Abstract: Provided are apparatuses and method for the thermal processing of a substrate surface, e.g., controlled laser thermal annealing (LTA) of substrates. The invention typically involves irradiating the substrate surface with first and second images to process regions of the substrate surface at a substantially uniform peak processing temperature along a scan path. A first image may serve to effect spike annealing of the substrates while another may be used to provide auxiliary heat treatment to the substrates before and/or after the spike annealing. Control over the temperature profile of the prespike and/or postspike may also reduce stresses and strains generated in the wafers. Also provided are microelectronic devices formed using the inventive apparatuses and methods.Type: ApplicationFiled: October 6, 2008Publication date: April 8, 2010Inventors: Arthur W.

Patent number: 6214119Abstract: The present invention includes plural plasma processing vessels and a wafer queuing station arrayed with a wafer transfer arm in a controlled environment. Wafers are movable within the controlled environment one at a time selectably between the several plasma vessels and the wafer queuing station without atmospheric or other exposure so that possible contamination of the moved wafers is prevented. The system is selectively operative in either single-step or multiple-step processing modes, and in either of the modes, the several plasma etching vessels are operable to provide a desirably high system throughput. In the preferred embodiment, the several plasma vessels and the queuing station are arrayed about a closed pentagonal locus with the wafer transfer arm disposed within the closed locus.Type: GrantFiled: November 18, 1998Date of Patent: April 10, 2001Assignee: Applied Materials, Inc.Inventors: Joseph A.

Patent number: 4473435Abstract: Method and apparatus for masked etching of a polysilicon surface layer or film to expose a dielectric underlying layer or film on a semiconductor material using ion bombardment from an ionized mixture of a fluorine based gas with a chlorine or bromine containing gas. A particularly useful gas is a mixture of sulfur hexafluoride and Freon 115 gases (C.sub.2 ClF.sub.5). The mixture of gases achieves the result of highly selective etching through the polysilicon film without significantly attacking the underlying dielectric film and without significant undercutting in the polysilicon film or etching of the masking layer.Type: GrantFiled: March 23, 1983Date of Patent: September 25, 1984Assignee: DrytekInventors: Arthur W.
