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

Ⅰ. INTRODUCTION
Ⅰ. LED
LED(Light Emitting Diode)는 반도체에 전압을 인가할 때 생기는 발광현상을 이용한 광원이다. 전기를 통해주면 전자가 에너지 레벨이 높은 곳에서 낮은 곳으로 이동하면서 특정한 파장의 빛을 내는 화합물 반도체에
Vacuum and freeze drying processes are used for products with delicate flavours and textures like coffee granules, eggs, prawns and vegetables. The process involves freezing, and evaporating the ice away, under reduced pressure. It is an expensive process but gives a produce which is high in flavour and palatability. Milk may be dried on rollers or by spraying concentrated milk into hot air chamb
COSMOS®: Real-Time Package Tracking
COSMOS (Customer Operations Service Master On-line System) is a computerized package tracking system that monitors every phase of the delivery cycle at FedEx. FedEx employees constantly input information into COSMOS by several means.
Customer service representatives enter shipping information into COSMOS through computer terminals, alerting the dispatche
