[3] Thin Film Deposition
초집적 반도체를 구성하는 소자들은 그 특성상 그 크기가 매우 얇아(작고) 미세한 조직을 가진다. 그리고 이것은 박막 증착(TFD = Thin Film Deposition) 공정을 통해 제작된다. 박막 증착이란 이름 그대로 표면에 얇은 막을 씌우는 기술을 뜻하는데 이 공정을 통해 기판(substrate)이나 이전에
For comparative purposes the corresponding peak-to-background ratios were: 4.4, 7.1 and 7.9 for 5kV, 10kV and 15kV, respectively. In addition to Nb, other elemental peaks could be detected from the surrounding materials. The Al and Si peaks were generated from the holder (the O peak was visible due to oxidation of the holder itself), the Ni peak originated from the sample grid and the extraction
-참이슬
Nowadays 참이슬 is major alcohol beverage in Korea. Also 참이슬 is major product which generates revenue in Jinro company. 참이슬 has new domestic sales record.
-참이슬 Fresh
참이슬 Fresh is similar to 참이슬. However Fresh is lower alcohol degree than 참이슬. They use the method which refines natural bamboo charcoal, the BCA method of construction, and the Marr

Fast deposition speed
Cheap process device
1. Partially different thickness
2. Difficult to control the element ratio
3. Hard to deposition the complex material layer
4. Low film quality
3.Material to be evaporated by e-beam
