Patent number: 10794593Abstract: A vaporization pipe for a kerosene lamp has an oil tube, a thermally conductive tube, and a first passage. The oil tube is made of steel and has a vaporization jet on a top of the oil tube. The thermally conductive tube is mounted in the oil tube and forms a first channel. The first passage is disposed between the oil tube and the thermally conductive tube. The steel oil tube can prevent the vaporization pipe from being softened and bent during the preheating of vaporization pipe or burning of the kerosene, and thus a useful lifetime of the vaporization pipe is prolonged. The thermally conductive tube is made of high-thermal-conductivity material for keeping the vaporization pipe with adequate thermal conductivity and improving a burning rate of kerosene. The first passage allows the kerosene to flow upward, preventing the kerosene from being vaporized incompletely because the kerosene is over pressurized.Type: GrantFiled: March 6, 2018Date of Patent: October 6, 2020Inventors: Po-Kai Tsao, Chih-Fang Lee

Patent number: 10734228Abstract: Embodiments are disclosed for processing microelectronic workpieces to apply stress engineering to self-aligned multi-patterning (SAMP) processes. The disclosed processing methods utilize stress in a substrate in a SAMP process to improve resulting pattern parameters. Initially, a high stress film is deposited on the frontside and the backside of the substrate, and the high stress film provides biaxial stress to the substrate due to the deposition process for the high stress film. Next, a SAMP process is performed to form spacers in a spacer pattern. This spacer pattern is then transferred to underlying layers to form a patterned structure. The high stress film provides axial stress in at least one direction along a portion of the patterned structure during the pattern transfer thereby improving resulting pattern formation.Type: GrantFiled: December 6, 2018Date of Patent: August 4, 2020Assignee: Tokyo Electron LimitedInventors: Eric Chih-Fang Liu, Akiteru Ko, David L.
