Patent number: 11735473Abstract: Methods of manufacturing memory devices having memory cells and corresponding selectors, and associated systems and devices, are disclosed herein. In one embodiment, a method of manufacturing a memory device includes (a) removing a protection layer formed over the memory cells and (b) forming a cap layer over the memory cells before forming a conductive via through the memory device. The cap layer is configured to protect the memory cells during operation and can comprise a resistive material. The protection layer can be more efficiently removed with improved process margin and less device health impact using a polishing process before the conductive via is formed, thus increasing the manufacturing margin of the memory device.Type: GrantFiled: November 11, 2021Date of Patent: August 22, 2023Assignee: Micron Technology, Inc.Inventors: Jukuan Zheng, Sri Sai Sivakumar Vegunta, Kevin L. Baker, Josiah Jebaraj Johnley Muthuraj, Efe S. Ege

Patent number: 9890604Abstract: An apparatus for activating a wellbore tool may include a first sub, gas transfer sub, and a second sub. The first sub has an igniter that generates a flame output that ignites a power charge. The power charge generates a high pressure gas when ignited by the flame output. The gas transfer sub has a first end receiving a portion of the power charge, a longitudinal bore, and a plurality of flow passages radiating from the longitudinal bore. The flow passages provide fluid communication between the longitudinal bore and the first sub. The second sub includes a shaft having a first end connectable with the gas transfer sub.Type: GrantFiled: March 26, 2015Date of Patent: February 13, 2018Assignee: OWEN OIL TOOLS LPInventors: Jeffrey D. Wood, Kevin L. Baker, Matthew C. Clay

Patent number: 9771769Abstract: An apparatus for activating a wellbore tool includes a cylinder, a shaft, and a pressure dissipater. The cylinder has a first inner surface defining a smooth bore section and a second inner surface adjacent to the first inner surface. The shaft has a piston section that includes at least one seal forming a fluid seal with the first inner surface when the seal is at a nominal diameter. The pressure dissipater is formed along the second inner surface of the cylinder, the pressure dissipater contacts and physically destabilizes the at least one seal after the at least one seal exits the smooth bore section.Type: GrantFiled: April 28, 2015Date of Patent: September 26, 2017Assignee: OWEN OIL TOOLS LPInventors: Kevin L. Baker, Timothy E. LaGrange

Patent number: 9207194Abstract: A neutron imaging system detects both the phase shift and absorption of neutrons passing through an object. The neutron imaging system is based on either of two different neutron wavefront sensor techniques: 2-D shearing interferometry and Hartmann wavefront sensing. Both approaches measure an entire two-dimensional neutron complex field, including its amplitude and phase. Each measures the full-field, two-dimensional phase gradients and, concomitantly, the two-dimensional amplitude mapping, requiring only a single measurement.Type: GrantFiled: March 7, 2013Date of Patent: December 8, 2015Assignee: Lawrence Livermore National Security, LLCInventor: Kevin L.

Patent number: 7351191Abstract: A method for solidifying an oil-contaminated aqueous waste in situ or ex situ includes the step of combining the oil-contaminated waste with a clay, a cement and a sulfite salt solidification agent to form a solidified waste matrix, wherein the solidification agent undergoes hydration and cementation reactions in the waste matrix in the presence of water. Optionally, heavy metal stabilizing agents can also be combined with the waste.Type: GrantFiled: September 2, 2005Date of Patent: April 1, 2008Assignee: RMT, IncInventors: Ajit K. Chowdhury, Jeff C.
