[3] Thin Film Deposition
초집적 반도체를 구성하는 소자들은 그 특성상 그 크기가 매우 얇아(작고) 미세한 조직을 가진다. 그리고 이것은 박막 증착(TFD = Thin Film Deposition) 공정을 통해 제작된다. 박막 증착이란 이름 그대로 표면에 얇은 막을 씌우는 기술을 뜻하는데 이 공정을 통해 기판(substrate)이나 이전에

Marketing Problem
Compared to other competitors,
Customers defection rate is 84% high.
- Customer Information leakage
- Forced termination 2G service
Low quality of customer service
caused high defection rate.
First, KT company is compared to other competitors, customers defection rate is 84% high.
And we think that the Kt has marketing problem. For example, leakage of customer
leakage current low and protect the film from hot carrier injection.
Thermodynamic stability
Minimization of electric fields due to phonons in the dielectric to reduce scattering in the Si substrate so as to achieve high mobility of charge carriers in the MOSFET channel
Minimization of the concentration of electrically charged and/or electrically active defects in the film
