has more strong light intensity than single chip WLED, but process is too complicate and not cost effective. And electron transfer is slow caused by 2-dimensional chip.
2. RGB-LED Nano Wire ??
Existed RGB-LED structure is 3-chip structure(emit red, green, blue) and mixture structure that constructed with One single chip(emit blue light) and different size quantum dots(emit light by
4. Dopant Barrier <불순물 장벽>
- 산화층이 실리콘 표면에서 성장하면 불순물 물질이 wafer로 들어가는 곳에 창을 생성시키기
위해서 Mask 개방으로 SiO2를 식각, 이때 산화물은 dopant의 확산으로부터
silicon의 표면을 보호.
- 선택적인 dopant의 도핑가능

process, identify the bottleneck area(s). What are the causes? What recommendations, both short-term and long-term, would you make to solve the bottleneck problem?
The bottleneck area in the process is drying. There are about 19,000bbls go through the process (average 75bbls * 243 trucks). Among them, 13,330bbls are wet berries (70% of total processed berries), which should go through drying pro
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. Consequently, the techniques are so complicated and diverse to state in one paragraph. This report divides the methods into several categories, physical, biological, and chemical, and introduces each technology briefly.
