Patent number: 10354912Abstract: Forming self-aligned vertical interconnect accesses (vias) in interconnect structures for integrated circuits (ICs) is disclosed. To reduce or avoid misalignment of a via to an underlying, interconnected metal line, vias are fabricated in the interconnect structure to be self-aligned with an underlying, interconnected metal line. In this regard, underlying metal lines are formed in a dielectric layer. A recess is formed in an underlying metal line below a top surface of an inter-layer dielectric. A stop layer is disposed above the inter-layer dielectric and within the recess of the underlying metal line. The stop layer allows a via tunnel to be formed (e.g., etched) down within the recess of the underlying metal line to self-align the via tunnel with the underlying metal line. A conductive material is then deposited in the via tunnel extending into the recess to form the self-aligned via interconnected to the underlying metal line.Type: GrantFiled: August 5, 2016Date of Patent: July 16, 2019Assignee: QUALCOMM IncorporatedInventors: Jeffrey Junhao Xu, John Jianhong Zhu, Choh Fei Yeap

Patent number: 10269627Abstract: A device, structure, and method are provided whereby an insert layer is utilized to provide additional support for surrounding dielectric layers. The insert layer may be applied between two dielectric layers. Once formed, trenches and vias are formed within the composite layers, and the insert layer will help to provide support that will limit or eliminate undesired bending or other structural motions that could hamper subsequent process steps, such as filling the trenches and vias with conductive material.Type: GrantFiled: August 25, 2017Date of Patent: April 23, 2019Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chia-Cheng Chou, Chih-Chien Chi, Chung-Chi Ko, Yao-Jen Chang, Chen-Yuan Kao, Kai-Shiang Kuo, Po-Cheng Shih, Tze-Liang Lee, Jun-Yi Ruan

Patent number: 10247700Abstract: A technique relates to manufacturing a nanogap. An oxide layer is disposed on top of a substrate. A release layer is disposed in a pattern on top of the oxide layer. A patterned trench is etched into the oxide layer using the pattern of the release layer. A metal layer is disposed on the release layer and in the patterned trench. A polish removes the release layer, thereby removing both the release layer and a portion of the metal layer having been disposed on top of the release layer, such that the metal layer remaining includes a first metal part and a second metal part connected by a metal nanowire. The metal layer remaining is coplanar with the oxide layer. A nanochannel is formed in the oxide layer in a region of the metal nanowire. The nanogap is formed in the metal nanowire separating the first and second metal parts.Type: GrantFiled: October 30, 2015Date of Patent: April 2, 2019Assignees: INTERNATIONAL BUSINESS MACHINES CORPORATION, BIONANO GENOMICS, INC.Inventors: Huan Hu, Michael F.

Patent number: 10043707Abstract: A first plate-able layer is selectively plated to form one or more redistribution paths. The connection points of an IC package are connected to the redistribution paths, and the IC package is over molded for stability. The first plate-able layer is then removed, leaving the one or more redistribution paths exposed. The redistribution paths allow one or more contact points of the IC package to be moved to a new location in order to facilitate integration of the IC package into a system. By plating the redistribution paths up from the first plate-able layer, fine geometries for repositioning the contact points of the IC package with minimal conductor thickness are achieved without the need for specialized manufacturing equipment. Accordingly, a redistribution layer is formed at a low cost while minimizing the impact of the layer on the operation of the IC device.Type: GrantFiled: March 26, 2013Date of Patent: August 7, 2018Assignee: Qorvo US, Inc.Inventors: John August Orlowski, David Jandzinski
