Patent number: 9748148Abstract: Embodiments of the disclosure provide apparatus and methods for localized stress modulation for overlay and edge placement error (EPE) using electron or ion implantation. In one embodiment, a process for correcting overlay error on a substrate generally includes performing a measurement process in a metrology tool on a substrate to obtain a substrate distortion or an overlay error map, determining doping parameters to correct overlay error or substrate distortion based on the overlay error map, and providing a doping recipe to a doping apparatus based on the doping parameters determined to correct substrate distortion or overlay error. Embodiments may also provide performing a doping treatment process on the substrate using the determined doping repair recipe, for example, by comparing the overlay error map or substrate distortion with a database library stored in a computing system.Type: GrantFiled: June 10, 2015Date of Patent: August 29, 2017Assignee: APPLIED MATERIALS, INC.Inventors: Ellie Y.

Patent number: 9728406Abstract: Embodiments described herein generally relate to methods for device patterning. In various embodiments, a plurality of protrusions and gaps are formed on a substrate, and each gap is formed between adjacent protrusions. Each protrusion includes a first line, a second line and a third line. The first and third lines include a first material, and the second lines include a second material that is different from the first material. A fourth line is deposited in each gap and the fourth line includes a third material that is different than the first and second materials. Because the first, second and third materials are different, one or more lines can be removed by selective etching while adjacent lines that are made of a different material may not be covered by a mask. The critical dimensions (CD) and the edge displacement errors (EPE) of the mask are increased.Type: GrantFiled: August 4, 2015Date of Patent: August 8, 2017Assignee: APPLIED MATERIALS, INC.Inventors: Huixiong Dai, Christopher S.

Publication number: 20170097576Abstract: A calibration curve for a wafer comprising a layer on a substrate is determined. The calibration curve represents a local parameter change as a function of a treatment parameter associated with a wafer exposure to a light. The local parameter of the wafer is measured. An overlay error is determined based on the local parameter of the wafer. A treatment map is computed based on the calibration curve to correct the overlay error for the wafer. The treatment map represents the treatment parameter as a function of a location on the wafer.Type: ApplicationFiled: October 2, 2015Publication date: April 6, 2017Inventors: Mangesh Bangar, Bruce E.

Patent number: 9343309Abstract: Methods of laterally oxidizing features of a patterned substrate are described. A capping layer may be disposed above lateral features to laterally confine the oxidation. The oxidizable features may be material patterned near the optical resolution of a photolithography system using a high-resolution photomask. The oxidizable features may be wider than the spaces between the oxidizable features and may be about three times the width of the spaces. Oxidized portions may be formed on either side of repeated oxidizable features. The unoxidized portions may then be removed as part of a self-aligned double patterning (SADP) process. A gapfill layer deposited thereon may be etched or polished back to form alternating fill and non-sacrificial features.Type: GrantFiled: March 13, 2015Date of Patent: May 17, 2016Assignee: Applied Materials, Inc.Inventors: Mangesh Bangar, Liyan Miao, Huixiong Dai

Patent number: 9337051Abstract: Embodiments of the disclosure generally provide a method of forming a reduced dimension pattern in a hardmask that is optically matched to an overlying photoresist layer. The method generally comprises of application of a dimension shrinking conformal carbon layer over the field region, sidewalls, and bottom portion of the patterned photoresist and the underlying hardmask at temperatures below the decomposition temperature of the photoresist. The methods and embodiments herein further involve removal of the conformal carbon layer from the bottom portion of the patterned photoresist and the hardmask by an etch process to expose the hardmask, etching the exposed hardmask substrate at the bottom portion, followed by the simultaneous removal of the conformal carbon layer, the photoresist, and other carbonaceous components. A hardmask with reduced dimension features for further pattern transfer is thus yielded.Type: GrantFiled: July 14, 2015Date of Patent: May 10, 2016Assignee: APPLIED MATERIALS, INC.Inventors: Bencherki Mebarki, Bok Hoen Kim, Deenesh Padhi, Li Yan Miao, Pramit Manna, Christopher Dennis Bencher, Mehul B.
