濺射離子槍主要用途:
濺射清洗/表面科學中樣品表面處理, MBE and HV 濺射過程
離子輔助沉積
離子束濺射鍍膜
反應離子刻蝕
技術指標:
離子能量 | 25eV - 5keV |
總的離子束電流 | 1mA (at 5kV with Argon) High Current Version: up to 4mA (at 5kV with Argon) |
電流密度 | 120μA/cm2 at 100mm working distance |
離子束發散角 | Ion energy dependant (typically 15°) |
工作距離 | 100 mm (typically) |
等離子體杯 | Alumina (superior than other dielectric materials due to highest yield of secondary electrons) |
氣體進氣口徑 | CF-16 (1.33“OD) |
氣體流速 | 1 - 5 sccm (1,5 sccm typical, gas dependant) |
工作真空度 | 10-6mbar - 10-3mbar (1x10-5mbar typical in chamber with 300l/s pimp). Low 10-6 mbar range possible - beam current then 140μA max. |
激發模式 | 微波放電等離子體 (無燈絲) |
