1. Introduction
"Relationships with customers and suppliers allow us to know what we must be able to supply in real time and then very quickly and precisely meet that demand while maintaining low inventory."
(Dave Schneider, engineering manager of Dell)
As of July 2002, Dell Computer Corporation (Dell) was the world’s largest direct selling computer company, with 34,800 employees in more tha
코카콜라는 1886년 미국 조지아 주 애틀랜타에서 약사인 존 펨버튼이 두통과 숙취해소를 위해 코카와 콜라를 섞고 그 외에 10여 가지 다른 성분을 첨가하여 만든 음료수에서 시작되었다. 그 후에 동시의 약제사인 캔들러가 제조·판매권을 매입하여 1919년 현재의 회사조직을 설립하고 청량음료로서 판매
3. Requirements of EUV resist
EUV is highly absorbed by all materials, even EUV optical components inside the lithography tool are susceptible to damage, mainly manifest as observable ablation. Such damage that is associated with the high-energy process of generating EUV radiation is a new concern specific to EUV lithography .
EUVL's shorter wavelength also increases flare, resulting in less
