technology. Actually, there are many problem compare with semiconductor processing like technology of removal defect, accuracy of pattern and registration. But recently as directed self-assembly(DSA) technology is advanced, that can reduce the defect of pattern which is substitution of existing optical lithography technology and will be important role in making semiconductor minute pattern.

Figure 13 shows that cryo pump is cooling pump. It means this pump is cooling, liquefaction and store air, not pumping. Generally, it has 3 processes like condensation, absorption and trap at low temperature. The cooled air or molecules do not have any momentum so it is no possibility to heat any molecules. It means vacuum.
Cryo pump have High emission velocity and high emission capacity so it
1. Packaging의 정의
Packaging은 Wafer를 절단하여 Chip을 분리하고 이 Chip을 조립하여 실제 기판에 실장할 수 있도록 플라스틱수지 또는 세라믹을 이용하여 밀봉하는 작업이다. 따라서 Packaging은 반도체 및 전자기기를 최종 제품화하는 과정이라고 볼 수 있다. Packaging의 역할은 크게 세가지로 정리할 수 있는
technologies are around for preventing foods from the undesirable results. Specifically this report deals with the methods that inhibiting the growth of food-spoilage micro-organisms, which covers most of the food preservation technologies. Various modern technologies are applied to inhibit the growth of micro-organisms in food product as various food-spoilage micro-organisms are exit. Consequent
3.2.The first product (2007 - present)
3.2.1.Main article: Mastretta MXT
Mastretta (est. 1989) first announced production of their MXT through Automóvil Panamericano magazine in May 2007. Even though up to a year will have passed, September 2008 will see the production version of the first ever fully Mexican designed and engineered serial-produced sports car, the Mastretta MXT, an automo
