Properties of Electron Temperature and Electron Density in Inductively Coupled Xenon Plasma

유도결합형 제논 플라즈마의 전자온도, 전자밀도 특성

In this paper, parameters of electron temperature and density for the mercury-free lighting-source were measured to diagnosis and analyze in Xe based inductively coupled plasma(ICP). In results at several dependences of $20{\sim}100mTorr$ Xenon pressure, $50{\sim}200W$ RF power and horizontal distribution were especially mentioned. When Xe pressure was 20mTorr and RF power was 200W, the electron temperature and density were respectively 3.58eV and $3.56{\times}10^{12}cm^{-3}$. The key parameters of Xe based ICP depended on Xe pressure more than RF power that could be verified. A high electron temperature and low electron density with a suitable Xe pressure are indispensible parameters for Xe based ICP lighting-source.
