Patent number: 7309642Abstract: A method for forming quantum dots includes forming a superlattice structure that includes at least one nanostrip protruding from the superlattice structure, providing a quantum dot substrate, transferring the at least one nanostrip to the quantum dot substrate, and removing at least a portion of the at least one nanostrip from the substrate. The superlattice structure is formed by providing a superlattice substrate, forming alternating layers of first and second materials on the substrate to form a stack, cleaving the stack to expose the alternating layers, and etching the exposed alternating layers with an etchant that etches the second material at a greater rate than the first to form the at least one nanostrip.Type: GrantFiled: November 9, 2005Date of Patent: December 18, 2007Assignee: Hewlett-Packard Development Company, L.P.Inventors: William M. Tong, M. Saif Islam

Patent number: 7309644Abstract: A system and method are provided to fabricate thin-films having different physical property parameters or having physical property parameters that continuously change across functionally broadband monolithic device arrays. The fabrication method deposits the thin-film including layers on a substrate of a monolithic chip. The method defines a desired gradient profile of each layer forming the thin-film, each gradient profile including a desired thinnest profile and a desired thickest profile. The method further aligns an aperture of a mask over the substrate to form the thin-film and calculates a shutter speed for the specified gradient profile of each layer across the desired area of the substrate, and deposits each layer on the substrate, through the aperture, as the aperture of the shutter moves at the calculated shutter speed from the desired thinnest profile of each layer to the desired thickest profile of each layer.Type: GrantFiled: November 29, 2004Date of Patent: December 18, 2007Assignee: University of Maryland, College ParkInventors: Ichiro Takeuchi, Wei Yang, Kao-Shuo Chang, Ratnakar D.

Patent number: 7309645Abstract: The semiconductor thin film crystallization method comprises the step of forming a semiconductor thin film 14 over a substrate 10; the step of forming band-shaped portion 16 for blocking crystal growth of the semiconductor thin film in the semiconductor film or over the semiconductor film; and the step of causing an energy beam 18 of a continuous wave to scan in a direction intersecting the longitudinal direction of the portion for blocking crystal growth. The energy beam is caused to scan, intersecting the portion for blocking the crystal growth, whereby the crystal growth can be interrupted when the application region of the energy beam intersects the portions for blocking the crystal growth. Even when a solid semiconductor thin film which is not patterned in islands is crystallized, the semiconductor thin film of good crystals can be formed with high yields while the film is prevented from peeling.Type: GrantFiled: March 30, 2005Date of Patent: December 18, 2007Assignee: Sharp Kabushiki KaishaInventor: Nobuo Sasaki

Patent number: 7309646Abstract: A feature in a layer is provided. A photoresist layer is formed over the layer. The photoresist layer is patterned to form photoresist features with photoresist sidewalls, where the photoresist features have a first critical dimension. A fluorine-containing conformal layer is deposited over the sidewalls of the photoresist features to reduce the critical dimensions of the photoresist features. Fluorine is removed from the conformal layer, while the remaining conformal layer is left in place. Features are etched into the layer, wherein the layer features have a second critical dimension, which is less than the first critical dimension.Type: GrantFiled: October 10, 2006Date of Patent: December 18, 2007Assignee: LAM Research CorporationInventors: Dongho Heo, Jisoo Kim, S.
