4.1 RCA cleaning
RCA cleaning is a series of rinsing procedure prior to experiment with Si wafer. The purpose of the RCA clean is to remove organic contaminants (such as dust particles, grease or silica gel) from the wafer surface. There are three steps to be performed. The first step is to remove organic contaminant from surface of wafer. Second step is to remove any oxide layer

value of Vfb and C-V curve will shift by amount of the charge divided by Cox of Ci. The amount of shifting decreases as the position of fiexed charges is far from interface on the substrate and shifting will not exist any more when it is located on the interface between metal and interface. Mobile charges has the same effect. But it makes the curve shift toward applied voltage because the movemen
메카트로닉스 계측 실험 final project로 PC’s DAQ와 AVR을 이용한 ‘기타 오토 튜닝 시스템’ 설계를 하게 되었다.

1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine
○ PECVD
∙ What is PECVD?
⇒ Radio frequency(RF) is used to induce plasma in the deposition gas.
⇒ This results in a higher deposition rate at relatively low temperatures.
⇒ With the plasma enhanced CVD process is the deposition at temperature around 300℃ allows.
⇒ The temperature will be through encouragement of a plasma with high frequency electric fields triggered.
