Publication number: 20240141541Abstract: An apparatus for electroplating a metal on a semiconductor substrate with high control over plated thickness on a die-level includes an ionically resistive ionically permeable element (e.g., a plate with channels), where the element allows for flow of ionic current through the element towards the substrate during electroplating, where the element includes a plurality of regions, each region having a pattern of varied local resistance, and where the pattern of varied local resistance repeats in at least two regions. An electroplating method includes providing a semiconductor substrate to an electroplating apparatus having an ionically resistive ionically permeable element or a grid-like shield having a pattern correlating with a pattern of features on the substrate, and plating metal, while the pattern on the substrate remains spatially aligned with the pattern of the element or the grid-like shield for at least a portion of the total electroplating time.Type: ApplicationFiled: March 15, 2022Publication date: May 2, 2024Inventors: Lee Peng Chua, Gabriel Hay Graham, Bryan L. Buckalew, Stephen J. Banik, II, Santosh Kumar, James Isaac Fortner, Robert Rash, Steven T. Mayer

Patent number: 9907636Abstract: A light irradiation device that emits a light patch of uniform intensity. The device may be a dental light wand. The device has a light source, a lenslet array and an optional relay lens. The light source may be a laser or a collimated LED. Each lenslet of the lenslet array has two convex surfaces, a front convex surface, and a rear convex surface that is opposite to the front convex surface. The front convex surface has a focal point on the principal plane of the rear convex surface. The focal length of the front convex surface differs from the focal length of the rear convex surface. Light beams emitted by the light source pass through the lenslet array, and if a relay lens is present then pass through the relay lens, forming a light patch of uniform intensity.Type: GrantFiled: July 1, 2015Date of Patent: March 6, 2018Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Zhisheng Yun, Rudolf Schmid, James L.

Publication number: 20150237326Abstract: A 3D image apparatus using a single optical channel for capturing multiple view-angle images of an object for use in generating a 3D image or model of the object. The apparatus includes within the optical train an active optical component, an aperture plate having an aperture, a lens for focusing light from the aperture, and an image sensor. The active optical component has a changeable shape or position for providing first and second optical wavefronts through the aperture and focused by the lens onto the image sensor from first and second view angles of the object. The second optical wavefront is shifted by the active optical component on the image sensor with respect to the first optical wavefront in order to provide multiple view-angle images along the single optical channel, which can be used to generate a 3D model or image of the object.Type: ApplicationFiled: February 14, 2014Publication date: August 20, 2015Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: Zhisheng Yun, James L.

Publication number: 20140229418Abstract: Methods and systems for designing an experiment using a computer to determine whether the experiment is a true experiment are described. These approaches allow a user who is unsophisticated in the complexities of true experimental design to design and deploy an experiment that produces substantially confound-free results and can be used to determine and quantify any causal relationship between independent and dependent variables. The computer may select one or more independent and/or dependent variables of the experiment or may assist the user in selection of independent and/or dependent variables. Formation of control and treatment groups, randomization and/or blocking to reduce the effects of confounding variables may be performed by the computer with or without input from the user.Type: ApplicationFiled: April 16, 2014Publication date: August 14, 2014Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: James L.
