1. 전자파 간섭현상 (EMI)
3. 연구 과정 및 분석
목차
4. 향후 연구 계획
2. 연구 계획
1. 전자파 간섭현상 (EMI)
EMI : Electromagnetic Interference (전자파 간섭)
■ 전자파 : 전계와 자계가 90도로 이루어진 전파
■ 전자기기간의 노이즈 발생
■ 인간의 인체에 유해 (각종 질환 유발)
Shielding Effectiveness Good conductor approximation Thickness at less than skin depth
(Z0 = 377ohm)
Requirement of commercial
EMI Shielding Application
SE ≥ 20dB
Sheet resistance (면저항)의 영향이 지배적
EMI SE (Shielding Effectiveness) Equation
2. 연구 계획

사용 장비
증착 장비
▶ PVD (Physical Vapor Deposition)
<Sputtering>
▶ Plasma ion (Ar+)을 Target에 충돌시켜
분리된 Target atom을 Substrate에 증착시
키는 공정
▶ CVD (chemical Vapor Depositon)보다
다양한 물질 증착 가능
▶ 우수한 Step coverage, 고순도 증착
▶ 대면적 공정 가능 → 상업적 강점
측정 장비
<UV-vis spectrophotometer> <4-point probe> <Hall effect measurement>
▶ 광학적 투과도/반사도/굴절률 측정 ▶ 박막의 면저항 (Sheet resistance)
측정
▶ 재료의 전기전도도/캐리어농도/
전자이동도 등 전기적 특성 측정
