    1. Introduction 1. ์„œ๋ก  Integrated systems combining sputtering deposition chambers with glove boxes are crucial for research involving air-sensitive materials. Dawoovac recently undertook a repair and overhaul project for such a complex system at a laboratory, comprising interconnected DC Sputtering, Glove Box, and RF Sputtering units. Maintaining the performance and reliability of these integrated systems requires specialized expertise. This case study details the overhaul process performed by Dawoovac. ์Šคํผํ„ฐ๋ง ์ฆ์ฐฉ ์ฑ”๋ฒ„์™€ ๊ธ€๋Ÿฌ๋ธŒ ๋ฐ•์Šค๋ฅผ ๊ฒฐํ•ฉํ•œ ์—ฐ๋™ ์‹œ์Šคํ…œ์€ ๊ณต๊ธฐ์— ๋ฏผ๊ฐํ•œ ์žฌ๋ฃŒ๋ฅผ ๋‹ค๋ฃจ๋Š” ์—ฐ๊ตฌ์— ํ•„์ˆ˜์ ์ž…๋‹ˆ๋‹ค. ๋‹ค์šฐ๋ฐฑ์€ ์ตœ๊ทผ ํ•œ ์—ฐ๊ตฌ์‹ค์— ์„ค์น˜๋œ DC ์Šคํผํ„ฐ๋ง, ๊ธ€๋Ÿฌ๋ธŒ ๋ฐ•์Šค, RF ์Šคํผํ„ฐ๋ง ์œ ๋‹›์ด ์ƒํ˜ธ ์—ฐ๊ฒฐ๋œ ๋ณตํ•ฉ ์‹œ์Šคํ…œ์— ๋Œ€ํ•œ ์ˆ˜๋ฆฌ ๋ฐ ์˜ค๋ฒ„ํ™€ ํ”„๋กœ์ ํŠธ๋ฅผ ์ˆ˜ํ–‰ํ–ˆ์Šต๋‹ˆ๋‹ค. ์ด๋Ÿฌํ•œ ์—ฐ๋™ ์‹œ์Šคํ…œ์˜ ์„ฑ๋Šฅ๊ณผ ์‹ ๋ขฐ์„ฑ์„ ์œ ์ง€ํ•˜๊ธฐ ์œ„ํ•ด์„œ๋Š” ์ „๋ฌธ์ ์ธ ๊ธฐ์ˆ ๋ ฅ์ด ์š”๊ตฌ๋ฉ๋‹ˆ๋‹ค. ๋ณธ ์‚ฌ๋ก€ ์—ฐ๊ตฌ๋Š” ๋‹ค์šฐ๋ฐฑ์ด ์ˆ˜ํ–‰ํ•œ ์˜ค๋ฒ„ํ™€ ๊ณผ์ •์„ ์ƒ์„ธํžˆ ์„ค๋ช…ํ•ฉ๋‹ˆ๋‹ค. 2.
