Publication number: 20240178319Abstract: A semiconductor device includes a substrate, an interfacial layer formed on the semiconductor substrate, and a high-k dielectric layer formed on the interfacial layer. At least one of the high-k dielectric layer and the interfacial layer is doped with: a first dopant species, a second dopant species, and a third dopant species. The first dopant species and the second dopant species form a plurality of first dipole elements having a first polarity. The third dopant species forms a plurality of second dipole elements having a second polarity. A first concentration ratio of the first concentration of the first dopant species to the second concentration of the second dopant species of the p-type transistor is different from a second concentration ratio of the first concentration of the first dopant species to the second concentration of the second dopant species of the n-type transistor.Type: ApplicationFiled: February 2, 2024Publication date: May 30, 2024Inventors: Hsiang-Pi Chang, Yen-Tien Tung, Dawei Heh, Chung-Liang Cheng, I-Ming Chang, Yao-Sheng Huang, Tzer-Min Shen, Huang-Lin Chao

Patent number: 10697604Abstract: A vehicle lamp for installing on a vehicle includes a projector lens, a reflector, a first light emitting element, a shield, and an optical grating unit. The projector lens has a light entry surface and a light exit surface. The first light emitting element is adjacent to a first focal point of the reflector, and is for emitting light towards the reflector. The shield is for blocking a portion of the light that is emitted from the first light emitting element to form a cut-off line in a light distribution pattern. The optical grating unit is for reflecting at least a portion of the light that has passed a second focal point of the reflector and that has not passed through the light exit surface of the projector lens.Type: GrantFiled: January 31, 2019Date of Patent: June 30, 2020Assignee: Hua Xin Optronics Co.Inventors: You-Kang Guan, I-Liang Huang

Patent number: 10508786Abstract: A vehicle lamp adapted to be installed on a vehicle includes a projector lens, a reflector, a light emitting element, and a grating plate. The projector lens has a light entry surface and alight exit surface. The light emitting element is disposed for emitting light towards the reflector, such that the light is reflected by the reflector to pass through the projector lens to form a light distribution pattern. The grating plate is for reflecting at least a portion of the light that has traveled ahead of a second focal point of the reflector and that has not passed through the light exit surface of the projector lens. An extension of the grating plate and the optical axis defines an angle between 0 degree and 45 degrees.Type: GrantFiled: April 1, 2019Date of Patent: December 17, 2019Assignee: Hua Xin Optronics Co.Inventors: You-Kang Guan, I-Liang Huang
