Patent number: 8692393Abstract: Better alignment mark designs for semiconductor devices may substantially lessen the frequency of layer misalignment scanner alignment problems. Exemplary alignment mark designs substantially avoid or minimize damage during the fill-in and etching and chemical mechanical processing processes. Thus, additional processing steps to even out various layers or to address the misalignment problems may also be avoided.Type: GrantFiled: June 12, 2012Date of Patent: April 8, 2014Assignee: Macronix International Co., Ltd.Inventor: Feng-Nien Tsai

Publication number: 20140092573Abstract: In one embodiment, a load frame and an integrated circuit device are aligned, with a base frame carried on a substrate, along a first alignment axis defined by a first alignment post extending from the base frame to the load frame, in a direction transverse to the substrate, and a first biasing device carried on the base frame is actuated to engage and bias the load frame toward the base frame aligned with the load frame, and to bias the integrated circuit toward the substrate. A latch latches the load and base frames together, aligned with and biased towards each other with the integrated circuit device and the substrate aligned with, and biased toward each other. Other aspects and features are also described.Type: ApplicationFiled: September 28, 2012Publication date: April 3, 2014Inventors: David J. LLAPITAN, Neal E. ULEN, Jeffory L. SMALLEY

Patent number: 8674355Abstract: A device includes a test unit in a die. The test unit includes a physical test region including an active region, and a plurality of conductive lines over the active region and parallel to each other. The plurality of conductive lines has substantially a uniform spacing, wherein no contact plugs are directly over and connected to the plurality of conductive lines. The test unit further includes an electrical test region including a transistor having a gate formed of a same material, and at a same level, as the plurality of conductive lines; and contact plugs connected to a source, a drain, and the gate of the transistor. The test unit further includes an alignment mark adjacent the physical test region and the electrical test region.Type: GrantFiled: December 29, 2010Date of Patent: March 18, 2014Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Huan-Chi Tseng, Heng-Hsin Liu, Shu-Cheng Kuo, Chien-Chang Lee, Chun-Hung Lin

Publication number: 20140065832Abstract: An overlay mark suitable for use in manufacturing nonplanar circuit devices and a method for forming the overlay mark are disclosed. An exemplary embodiment includes receiving a substrate having an active device region and an overlay region. One or more dielectric layers and a hard mask are formed on the substrate. The hard mask is patterned to form a hard mask layer feature configured to define an overlay mark fin. Spacers are formed on the patterned hard mask layer. The spacers further define the overlay mark fin and an active device fin. The overlay mark fin is cut to form a fin line-end used to define a reference location for overlay metrology. The dielectric layers and the substrate are etched to further define the overlay mark fin.Type: ApplicationFiled: September 4, 2012Publication date: March 6, 2014Applicant: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Chi-Wen Hsieh, Chi-Kang Chang, Chia-Chu Liu, Meng-Wei Chen, Kuei-Shun Chen
