Making the Wafer
-A seed crystal is suspended in a molten bath of silicon
-It is slowly pulled up and grows into an ingot of silicon
-The ingot is removed and ground down to diameter
-The end is cut off, then thin silicon wafers are sawn off (sliced) and polished
The growth of an ultra-pure layer of crystalline silicon
Approx 3% of wafer thickness
Glass/ITO/Cr substrate will be patterned by photolithography.
In AMOLED fabrication, TFT array is on the substrate. Anode electrodes is formed on that TFT. And these are covered with insulator.
PMOLED is formed anode, insulator, cathode separator in order.
This process form electrodes. Organic layer will be deposited on anode.
FMM method is used for small molecules materials
What is the Bio-fuel ?
- Bio-fuel is derived from biological materials which are commonly plant materials used. The purpose is to make a “sustainable transportation fuel” from biomass.
What is Bio-ethanol ?
- Bio-ethanol has been produced from biological source.
- It is produced in fermentation of sugars in the brewing industry. In this process glucose is

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
