Publication number: 20090101983Abstract: Components in integrated circuits (ICs) are fabricated as small as possible to minimize sizes of the ICs and thus reduce manufacturing costs per IC. Metal interconnect lines are formed on minimum pitches possible using available photolithographic printers. Minimum pitches possible for contacts and vias are larger than minimum pitches possible for metal interconnect lines, thus preventing dense rectilinear grid configurations for contacts and vias. The instant invention is an integrated circuit, and a method of fabricating an integrated circuit, wherein metal interconnect lines are formed on a minimum pitch possible using a photolithographic printer. Contacts and vias are arranged to provide connections to components and metal interconnect lines, as required by the integrated circuit, in configurations that are compatible with the minimum pitch for contacts and vias, including semi-dense arrays.Type: ApplicationFiled: October 18, 2007Publication date: April 23, 2009Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Steven Lee Prins, James Walter Blatchford

Publication number: 20090104564Abstract: The invention is directed to a method for patterning a material layer. The method comprises steps of forming a mask layer on the material layer. A multiple patterning process is performed on the mask layer for transferring at least a first pattern from a first photomask through a first photoresist and a second pattern from a second photomask from a second photoresist layer into the mask layer without performing any etching process. The mask layer exposes a portion of the material layer and the mask layer is patterned at the time that the first photoresist layer and the second photoresist layer are developed respectively. An etching process is performed to pattern the material layer by using the mask layer as an etching mask.Type: ApplicationFiled: October 17, 2007Publication date: April 23, 2009Applicant: MACRONIX INTERNATIONAL CO., LTD.Inventor: Chin-Cheng Yang

Publication number: 20090098487Abstract: A method of forming a variable pattern across a wafer using a reticle forms a plurality of first patterns on the wafer. The first pattern is repeated across the wafer and each first pattern has a first readable element. The method also forms a plurality of second patterns on the wafer. The second patterns is repeated across the wafer and each second pattern has a second readable element. The second patterns are positioned relative to the first patterns by aligning a first second pattern relative to one portion of a corresponding first pattern and then incrementally misaligning each successive second pattern in a row or a column relative to its corresponding first pattern. Thus, each corresponding first readable element and second readable element form a corresponding variable pattern.Type: ApplicationFiled: October 16, 2008Publication date: April 16, 2009Applicant: ANALOG DEVICES, INC.Inventors: Lee J.

Publication number: 20090087792Abstract: The present invention provides a method for manufacturing an electroluminescence element that has a light emitting layer containing a quantum dot and exhibits excellent life characteristics. In the method, patterning of the light emitting layer can be stably performed by a lift-off method. A photoresist layer is formed on a substrate having a first electrode layer. The photoresist layer is then exposed, developed, and patterned to ensure that a portion of the photoresist layer, which is located in a light emission area, is removed. A coating liquid containing a quantum dot having a silane coupling agent attached to the surface thereof is coated on the resultant substrate having the patterned photoresist layer and cured to form a light emitting layer. The remaining photoresist layer is then removed to lift off a portion of the light emitting layer, which is present on the photoresist layer.Type: ApplicationFiled: September 26, 2008Publication date: April 2, 2009Applicant: DAI NIPPON PRINTIG CO., LTD.Inventors: Yasuhiro IIZUMI, Masaya Shimogawara

Publication number: 20090087619Abstract: The present disclosure is directed to a method for preparing photomask patterns for a lithography process that employs a plurality of photomasks. The method comprises receiving data describing a drawn pattern. An edge of the drawn pattern is identified that can be defined using a first photomask and a second photomask, and the first photomask is chosen for patterning the edge. Patterns are formed for the first photomask and the second photomask, wherein the first photomask pattern is formed to pattern the edge, and the second photomask pattern is formed to have a wing adjacent to the edge for protecting the edge from double patterning. A process for patterning an integrated circuit device is also disclosed.Type: ApplicationFiled: September 28, 2007Publication date: April 2, 2009Inventors: Thomas J. Aton, Carl A. Vickery
