Patent number: 8860184Abstract: Spacer-based pitch division lithography techniques are disclosed that realize pitches with both variable line widths and variable space widths, using a single spacer deposition. The resulting feature pitches can be at or below the resolution limit of the exposure system being used, but they need not be, and may be further reduced (e.g., halved) as many times as desired with subsequent spacer formation and pattern transfer processes as described herein. Such spacer-based pitch division techniques can be used, for instance, to define narrow conductive runs, metal gates and other such small features at a pitch smaller than the original backbone pattern.Type: GrantFiled: December 29, 2011Date of Patent: October 14, 2014Assignee: Intel CorporationInventors: Swaminathan Sivakumar, Elliot N.

Publication number: 20140299997Abstract: Methods are disclosed, including for increasing the density of isolated features in an integrated circuit. Also disclosed are associated structures. In some embodiments, contacts are formed on pitch with other structures, such as conductive interconnects that may be formed by pitch multiplication. To form the contacts, in some embodiments, a pattern corresponding to some of the contacts is formed in a selectively definable material such as photoresist. Features in the selectively definable material are trimmed, and spacer material is blanket deposited over the features and the deposited material is then etched to leave spacers on sides of the features. The selectively definable material is removed, leaving a mask defined by the spacer material. The pattern defined by the spacer material may be transferred to a substrate, to form on pitch contacts. In some embodiments, the on pitch contacts may be used to electrically contact conductive interconnects in the substrate.Type: ApplicationFiled: June 23, 2014Publication date: October 9, 2014Inventors: Gurtej Sandhu, Mark Kiehlbauch, Steve Kramer, John Smythe

Patent number: 8853815Abstract: A semiconductor apparatus is provided herein for buffering of nets routed through one or more areas associated with a first power domain that is different from a second power domain associated with the buffers and the buffered nets by limiting placement of these buffers in patterned areas associated with the second power domain. This provides for the routing of the buffered nets to be determined not only based on the shortest distance to travel from Point A to Point B, but also takes into account routing congestion on the semiconductor apparatus. Consequently, if an area on the semiconductor apparatus is congested, the buffered nets may be routed around the congestion. As such, although a path taken by a particular signal through the integrated circuit is not a direct route, it may still be of a distance to support a speed at which the particular signal needs to be transferred.Type: GrantFiled: March 14, 2013Date of Patent: October 7, 2014Assignee: QUALCOMM IncorporatedInventors: Sundararajan Ranganathan, Paras Gupta, Raghavendra Dasegowda, Rajesh Verma, Parissa Najdesamii

Patent number: 8823007Abstract: An integrated MEMS System. CMOS and MEMS devices can be provided in order to form an integrated CMOS-MEMS system. The system can include a silicon substrate layer, a CMOS layer, MEMS and CMOS devices, and a wafer level packaging (WLP) layer. The CMOS layer can form an interface region, one which any number of CMOS MEMS devices can be configured. The integrated MEMS devices can include, but not exclusively, an combination of the following types of sensors: magnetic, pressure, humidity, temperature, chemical, biological, or inertial. Furthermore, the overlying WLP layer can be configured to hermetically seal any number of these integrated devices. The present technique provides an easy to use process that relies upon conventional process technology without substantial modifications to conventional equipment and process and reduces off-chip connections, which make the mass production of smaller and thinner units possible.Type: GrantFiled: October 27, 2010Date of Patent: September 2, 2014Assignee: mCube Inc.Inventor: Xiao “Charles” Yang
