LOT Materials Co., Ltd. was established in 2011 and has accumulated unique technological expertise in the manufacturing of core components for the semiconductor and display industries. Headquartered in Osan, Gyeonggi Province, its main business is the manufacturing of core materials for gas pumps and compressors. Currently, 138 employees are working.

"LOT Materials Co., Ltd. is a subsidiary of LOT Vacuum, which was the first in Korea to localize dry vacuum pumps essential for semiconductor and display manufacturing processes. We specialize in manufacturing and assembling processed products and pump racks used in pumps, establishing an independent production line to secure the best technology."

Business Areas

• Manufacturing of Semiconductor and Display Equipment Components: We operate a core business that designs, produces, and supplies high-precision machined parts required for semiconductor and LCD process equipment. We operate state-of-the-art processing facilities and precision measurement systems to meet the strict quality standards of our customers.
• Processing of Dry Vacuum Pump Core Components and Materials: We process all parts related to the rotor and housing, which are core components of dry vacuum pumps, and possess key technology for micron-level machining. We have also established production lines for pump racks and vacuum piping to enhance our technological capabilities.

Products

• Vacuum Gate Valve: It is a core control device that blocks or maintains a vacuum state between semiconductor and display process chambers. It is a high-performance component that precisely guides the movement path of the gate plate to minimize mechanical wear and maintain perfect airtightness.
• Dry Vacuum Pump Core Materials (Rotor, Housing, Pump Rack): We produce core components of dry vacuum pumps, such as rotors, housings, and pump racks, which are essential for manufacturing processes in semiconductors, displays, and solar power facilities. We provide high-quality components through micron-level precision machining technology.

Special Notes

• Unique Technology and Expertise: We have accumulated unique technological expertise in the manufacturing of core components for the semiconductor and display industries. We have proven our core manufacturing capabilities by acquiring certifications as a 'Specialized Company for Materials, Parts, and Equipment' and a 'Root Industry Company' designated by the Ministry of Trade, Industry and Energy.
• Introduction of Smart Factory System: We are maximizing production efficiency by introducing a smart factory system. By establishing MES, ERP, and G/W systems, we have systematized overall operations from production planning to monitoring and quality control, thereby increasing productivity.
• Stable Growth and Partnerships: We are a mid-sized manufacturing innovation company that continues stable growth through partnerships with major domestic semiconductor equipment manufacturers. We are expanding our technology portfolio through continuous investment in research and development.

Recruitment Information

• Main Hiring Positions: We primarily recruit for production roles, including MCT machining, material manager, semiconductor engineer, mechanical engineer, design engineer, R&D researcher, production/process manager, sales/marketing/trade, and accounting/tax/finance roles.
• Benefits: We provide welfare facilities such as a cafeteria, lounge, in-house restaurant, dormitory operation, recreational facilities, fitness center, and seminar rooms. Benefits include congratulatory/condolence leave, four major insurances, retirement pension, overtime pay, holiday (special work) pay, position allowance, support for family events, and health check-ups.

💡 A Word from JobPloy
LOT Materials Co., Ltd. is a mid-sized enterprise that precisely processes core components for the semiconductor and display industries. As there are many production and processing roles, acquiring relevant skills and increasing proficiency is important. The introduction of a smart factory system means that experience in operating automated facilities will be helpful for adapting to the job. Since dormitories are operated, it can be a good condition for foreign workers who wish to work from other regions.
