Patent number: 12248055Abstract: A method for recognizing a motion state of an object by using a millimeter wave radar having at least one antenna is disclosed. The method includes the following steps. A region is set to select an object in the region, wherein the object has M ranges and M azimuths between the object and the at least one antenna during a first motion time. Each of the M ranges and the M azimuths are projected on a two-dimensional (2D) plane to form M frames. The M frames are sequentially arranged into a first consecutive candidate frames having a time sequence. The first consecutive candidate frames are inputted into an artificial intelligence model to determine a motion state type of the first consecutive candidate frames.Type: GrantFiled: April 6, 2022Date of Patent: March 11, 2025Assignee: NATIONAL YANG MING CHIAO TUNG UNIVERSITYInventors: Jiun-In Guo, Hung-Yu Liu

Patent number: 12237216Abstract: A method for filling recessed features with a low-resistivity metal. The method includes providing a patterned substrate containing a recessed feature formed in a first layer and a second layer that is exposed in the recessed feature, forming a nucleation enhancement layer on a sidewall of the first layer in the recessed feature and depositing a metal layer in the recessed feature by vapor phase deposition, where the metal layer is deposited on the second layer and on the nucleation enhancement layer. An initial metal layer may be selectively formed on the second layer in the recessed feature before forming the nucleation enhancement layer.Type: GrantFiled: March 7, 2022Date of Patent: February 25, 2025Assignee: Tokyo Electron LimitedInventors: Kai-Hung Yu, Shihsheng Chang, Ying Trickett, Eric Chih-Fang Liu, Yun Han, Henan Zhang, Cory Wajda, Robert D.

Patent number: 5782997Abstract: Single crystal aluminum is deposited on SiGe structures to form metal interconnects. Generally, a method of forming single crystal aluminum on Si.sub.(1-X) Ge.sub.X is presented, including the steps of maintaining the substrate at certain temperature (e.g. between 300.degree. C. and 400.degree. C.) and pressure conditions (e.g. below 2.times.10.sup.-9 millibar) while aluminum atoms are deposited by a vacuum evaporation technique. This is apparently the first method of depositing single crystal aluminum on SiGe surfaces. Novel structures are made possible by the invention, including epitaxial layers 34 formed on single crystal aluminum 32 which has been deposited on SiGe 30. Among the advantages made possible by the methods presented are thermal stability and resistance to electromigration.Type: GrantFiled: June 7, 1995Date of Patent: July 21, 1998Assignee: Texas Instruments IncorporatedInventors: Chih-Chen Cho, Hung-Yu Liu
