Patent number: 12392049Abstract: Methods and electroplating systems for controlling plating electrolyte concentration on an electrochemical plating apparatus for substrates are disclosed. A method involves: (a) providing an electroplating solution to an electroplating system; (b) electroplating the metal onto the substrate while the substrate is held in a cathode chamber of an electroplating cell of electroplating system; (c) supplying the make-up solution to the electroplating system via a make-up solution inlet; and (d) supplying the secondary electroplating solution to the electroplating system via a secondary electroplating solution inlet. The secondary electroplating solution includes some or all components of the electroplating solution. At least one component of the secondary electroplating solution has a concentration that significantly deviates from its target concentration.Type: GrantFiled: November 6, 2023Date of Patent: August 19, 2025Assignee: Lam Research CorporationInventors: Zhian He, Shantinath Ghongadi, Quan Ma, Hyungjun Hur, Cian Sweeney, Quang Nguyen, Rezaul Karim, Jingbin Feng

Patent number: 8027771Abstract: There is provided a method to monitor a sensing system adapted to monitor an output of an electro-mechanical transmission. This includes monitoring rotational speed of a wheel operatively connected to a driveline operatively connected to the output of the electro-mechanical transmission. A first expected output of the transmission is determined based upon the output of the first sensor. A second expected output of the transmission is determined based upon a rotational speed of a torque-generative device operatively connected to the transmission. The first and second expected outputs and an output of the sensing system adapted to monitor the output of the electro-mechanical transmission are compared.Type: GrantFiled: September 13, 2007Date of Patent: September 27, 2011Assignee: GM Global Technology Operations LLCInventors: Ryan D.
