Patent number: 10566441Abstract: Methods of forming integrated circuits are provided herein. In an embodiment, a method of forming an integrated circuit includes providing a semiconductor substrate. The semiconductor substrate includes a plurality of gate structures that have sidewalls spacers disposed adjacent to the gate structures. A gap is defined between sidewall spacers of adjacent gate structures. The method proceeds with decreasing an aspect ratio between a width of the gap at an opening thereto and a depth of the gap, wherein an aspect ratio between a width of the gap at a base of the sidewall spacers and the depth of the gap remains substantially unchanged after decreasing the aspect ratio between the width of the gap at the opening thereto.Type: GrantFiled: February 14, 2018Date of Patent: February 18, 2020Assignee: GLOBALFOUNDRIES SINGAPORE PTE. LTD.Inventors: Hao Nong, Liang Li, Chiew Wah Yap, Ting Huo, Yung Fu Chong, Yun Ling Tan

Patent number: 10410854Abstract: The present disclosure generally relates to methods for cleaning the backside of a wafer. A wet cleaning method may be used by stripping off the uppermost spacer layers on the backside of the wafer using a cleaning solution. In one embodiment, hydrogen fluoride (HF) solution may be employed to remove the nitride/oxide spacer layer. In another embodiment, a dry cleaning method may be employed to etch the wafer at the bevel region. Residues are completely removed from the wafer backside. This method improves the yield and storage life of the semiconductor wafers.Type: GrantFiled: December 28, 2017Date of Patent: September 10, 2019Assignee: GLOBALFOUNDRIES SINGAPORE PTE.

Patent number: 10191705Abstract: During processing of job documents in a document processing workflow, execution of the workflow is stopped at a previously defined first sequentially processed node until no more of the job documents can be directed to the first sequentially processed node by the workflow. Then, the job documents that have been stopped at the first sequentially processed node are arranged in a document order, and the sequentially processed nodes are executed for each of the multiple job documents that have been stopped (and such job documents are processed one at a time through the sequentially processed nodes). Thus, execution waits until an immediately previous one of the job documents (in the document order) has finished processing at a previously defined last sequentially processed node before starting processing an immediately subsequent one of the job documents (in the document order) at the first sequentially processed node.Type: GrantFiled: May 4, 2015Date of Patent: January 29, 2019Assignee: Xerox CorporationInventors: Francisco M.

Patent number: 9431364Abstract: A multi-chip package is disclosed that has a construction capable of preventing and/or reducing electrical shorts caused by shifts in bond wires. The multi-chip package includes a die attach formed between connection points of a bond wire. The die attach is made of a non-conductive material and can be constructed so as to support or encompass a portion of the bond wire. By contacting the bond wire, the die attach restricts the motion of the bond wire by acting as a physical barrier to the bond wire's movement and/or as a source of friction. In this manner, undesired position shifts of the bond wires can be prevented, reducing device failures and allowing for improved manufacturing allowances.Type: GrantFiled: January 7, 2013Date of Patent: August 30, 2016Assignee: Cypess Semiconductor CorporationInventors: Kiah Ling Tan, Sally Yin Lye Foong, Lee Changhak, Chin Nguk Lai

Patent number: 9139924Abstract: For forming a nickel mold, a metal and a corresponding etchant are selected such that the etchant selectively etches the metal over nickel. The metal is sputtered onto a surface of a template having nano-structures to form a sacrificial layer covering the nano-structures. Nickel is electroplated onto the sacrificial layer to form a nickel mold, but leaving a portion of the sacrificial layer exposed. The sacrificial layer is contacted with the etchant through the exposed portion of the sacrificial layer to etch away the sacrificial layer until the nickel mold is separated from the template. Subsequently, the nickel mold may be replicated or scaled-up to produce a replicate mold by electroplating, where the replicate mold has nano-structures that match the nano-structures on the template. The metal may be copper.Type: GrantFiled: August 23, 2012Date of Patent: September 22, 2015Assignee: Agency for Science, Technology and ResearchInventors: Kambiz Ansari, Christina Yuan Ling Tan, Yee Chong Loke, Jarrett Dumond, Isabel Rodriguez
