Model of plasma immersion ion implantation for voltage pulses with finite rise and fall times

Abstract: In plasma immersion ion implantation, a target is immersed in a plasma and a series of negative, high-voltage pulses are applied to implant ions into the target. An approximate analytical model in one-dimensional planar geometry is developed to determine the time-varying implantation current, the total dose, and the energy distribution of the implanted ions for a voltage pulse with finite rise and fall times. Scaling rules are presented for the implanted current and energy distribution with respect to plasma d… Show more

“…The outer cylindrical electrode is grounded, while dual rf voltage and pulse sources are applied to the inner wire electrode at the axis of the cylinder. [10] is adopted. Helium is taken as the discharge gas, the species considered in the model are electrons ( e ), atomic ions ( He  ), molecular ions ( 2 He  ), and metastable particles ( * He ), their densities n are governed by the continuity equations:…”

“…Menurut Stewart dkk [8] , dalam eksperimen PIII waktu naik dan waktu turun pulsa tegangan merupakan bagian signifikan dari keseluruhan lebar pulsa, sehingga agar model yang dikembangkan ini lebih representatif dan lebih realistis, maka keadaan pulsa tegangan realistik ini seharusnya dimasukkan kedalam perhitungan. Model yang dikembangkan oleh Qin, dkk ini [7] , dikembangkan lagi oleh Cahyono [8] dengan menggunakan bentuk pulsa tegangan ini. Dalam studi c Jurusan Fisika FMIPA ITS 100209-1 ini model yang telah dikembangkan pada waktu yang lalu [9] , diperluas lagi dengan menggunakan bentuk target silinder dan bola.…”

“…Yang paling banyak digunakan adalah model sheath dinamis plasma spesies tunggal [1][2][3], walaupun dalam kenyataan plasma yang digunakan dalam proses PIII adalah plasma multispesies. Thomas [4] Di sini dikembangkan sebuah model sheath dinamis tanpa tumbukan untuk plasma multispesies. Model yang dikembangkan didasarkan pada massa efektif, yang merupakan fungsi komposisi dan massa dari spesies yang berbeda, untuk menentukan ekspansi sheath dan arus ion implan.…”
