Lithography
Si Wafer coated with PR
Spin coating
PR is coated evenly by turning round rapidly.
Exposure
Align the Mask exactly and emit UV.(fixed 10sec)
Observation
See the completed sample through SEM
Development
∙ Dip the sample in the alkaline solution.
→(process parameter : 10sec 60sec 180sec)
∙ Due to differences in solubility of the exposed portion to be dissolv
1. 서론
의식주는 인간의 가장 기본적인 생활이다. 그중에서도 식생활이 차지하는 중요성은 매우 높다. 특히, ‘국’과 ‘찌개’의 문화를 가지고 있는 한국사회의 식생활에서 냄비는 없어서는 안 될 중요한 역할을 한다. 광택이 나며 녹이 슬지 않고 깨끗이 씻기 쉬우며 오래 사용할 수 있다는 특성
5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug

2-1-1. Principle
“Developed a theoretical model to evaluate the overall heat transfer coefficient, considering both conduction through the solid and heat exchange from the solid surface to the gas.”
An accurate determination of the geometrical parameters of the foam was considering the difference in the pore size and the measured value res
