Company profile
YUJAY Technology Inc. was founded in 2007 with a foundation in vacuum and coating technologies, beginning with customized vacuum chambers and diffusion pumps. In 2013, the company launched its own coating-equipment line covering evaporation, sputtering, CVD, and ALD systems for optoelectronics and semiconductor applications. In 2025, YUJAY Technology Inc. partnered with Sindin to introduce surface-treatment and inspection systems including plasma cleaners, contact-angle measurement instruments, and automated inspection platforms for wafer processing, packaging, and advanced-material applications. The company also collaborates with Onework to integrate digital-twin solutions into semiconductor fabs and smart factories, offering BIM cloud management, asset monitoring, smart infrastructure, and carbon management. Beyond semiconductors, YUJAY Technology Inc. extends into medical devices and electromechanical project-management engineering; its Lungwin Negative Pressure Ventilator won the National Innovation Award, and its project-management division provides PMC services for TIA-942 Rated-3 electromechanical projects. The company describes its current offering as a combination of semiconductor process equipment, surface-inspection technologies, smart-factory digital twins, healthcare expertise, and electromechanical project-management capabilities for the semiconductor industry.
Exhibits
YUJAY Technology Inc. applies expertise in high-vacuum and ultra-high-vacuum systems, and its new factory centers on optoelectronic semiconductor process-equipment manufacturing while integrating coating-equipment manufacturing with process-technology R&D to provide customized process equipment. For non-standard processes, the company provides customized vacuum chambers, pumping systems, and helium-recovery systems, ranging from standalone R&D equipment to line-level automation and integration with facility and process requirements. Its thin-film deposition capabilities cover magnetron and multi-target confocal sputtering, vacuum evaporation, CVD, and ALD, with chamber design and process-parameter validation tailored to film materials and process conditions. For leak detection, YUJAY Technology Inc. combines high-precision helium mass spectrometry with automated leak-test stations and custom sealing fixtures designed around different workpiece geometries to establish quantitative leakage standards. Surface treatment and metrology include atmospheric and vacuum plasma activation or modification together with high-precision contact-angle and surface-free-energy measurement, linking surface treatment with quantitative data verification. Its business areas also include liquid-cooling and leak testing for thermal modules, power-condition inspection such as partial discharge, substation and thermal-imaging temperature monitoring, and medical-device development based on pressure-control technology for negative-pressure respiratory equipment. Application areas include semiconductor and advanced packaging, liquid-cooling modules and cold plates, Mini/Micro LED display processing, new-energy and storage battery-pack leak testing, automotive ECU protection and electromechanical leak testing, biomaterial surface activation, and customized research equipment for academic institutions. Technical services span PoC concept validation and facility layout through preventive maintenance, spare-parts management, retrofit upgrades, subcontracted contact-angle and surface-treatment evaluation, high-precision helium micro-leak testing with formal reports, and project delivery from on-site survey and Hook-up to FAT and SAT acceptance under PM or CM management. The vacuum-chamber and system-integration range includes customized vacuum chambers for CVD, PVD, vacuum transfer, and intermediate processes from high vacuum through ultra-high vacuum, as well as pumping systems configured according to process equipment, chamber volume, gas load, piping, and control requirements. Vacuum evaporation options include water-cooled resistance-heating systems for metal electrodes, organic films, and functional coatings, plus deep box-type organic and inorganic evaporation systems with low-temperature organic sources and inorganic or metal resistance sources for independent dual-source control and simultaneous co-evaporation. Sputtering options include a single-target direct planar magnetron system for research and pilot production and a multi-target confocal system in which targets are arranged around a common focal region at about 30° with substrate rotation for multi-material co-sputtering. The equipment range also includes CVD and LPCVD systems supporting atmospheric-pressure and low-pressure processes with water-cooled stainless-steel furnace heads, quartz tubes, and boats, ALD systems using self-limiting surface reactions for conformal films on high-aspect-ratio structures including Al₂O₃ and HfO₂, and organic sublimation purification equipment using independently controlled sublimation, transfer, and condensation or collection zones to create a thermal gradient. For system selection, the company asks customers to provide the workpiece or sample, dimensions, process objectives, capacity, site, and interface conditions, with the final configuration determined through engineering confirmation.
