Patent number: 9991102Abstract: A sputtering apparatus according to one embodiment of the present invention includes a substrate holder, a cathode unit arranged at a position diagonally opposite to the substrate holder, a position sensor for detecting a rotational position of the substrate, and a holder rotation controller for adjusting a rotation speed of the substrate according to the detected rotational position. The holder rotation controller controls the rotation speed so that the rotation speed of the substrate when the cathode unit is located on a side in a first direction as an extending direction of a process target surface of the relief structure is lower than the rotation speed of the substrate when the cathode unit is located on a side in a second direction which is perpendicular to the first direction along the rotation of the substrate.Type: GrantFiled: November 23, 2015Date of Patent: June 5, 2018Assignee: CANON ANELVA CORPORATIONInventors: Koji Tsunekawa, Masahiro Suenaga, Takeo Konno

Patent number: 9976212Abstract: In various embodiments, eroded sputtering targets are partially refurbished by spray-depositing particles of target material to at least partially fill certain regions (e.g., regions of deepest erosion) without spray-deposition within other eroded regions (e.g., regions of less erosion). The partially refurbished sputtering targets may be sputtered after the partial refurbishment without substantive changes in sputtering properties (e.g., sputtering rate) and/or properties of the sputtered films.Type: GrantFiled: July 31, 2014Date of Patent: May 22, 2018Assignee: H.C. STARCK INC.Inventor: Steven A. Miller

Patent number: 9972478Abstract: Methods and systems for controlling processing state of a plasma reactor to initiate processing of production substrates and/or to determine a ready state of a reactor after the reactor has been cleaned and needs to be seasoned for subsequent production wafer processing are provided. The method initiate processing of a substrate in the plasma reactor using settings for tuning knobs of the plasma reactor that are approximated to achieve desired processing state values. A plurality of data streams are received from the plasma reactor during the processing of the substrate. The plurality of data streams are used to identify current processing state values. The method includes generating a compensation vector that identifies differences between the current processing state values and the desired processing state values. The generation of the compensation vector uses machine learning to improve and refile the identification and amount of compensation needed, as identified in the compensation vector.Type: GrantFiled: September 16, 2016Date of Patent: May 15, 2018Assignee: Lam Research CorporationInventors: Joydeep Guha, John Daugherty, Vahid Vahedi, Richard Alan Gottscho
