    • A plasma processing apparatus includes a plurality of plasma processing units. Each of the plasma processing units has a plasma excitation electrode, a radiofrequency generator connected to the plasma excitation electrode, and a matching circuit which matches the impedance between the radiofrequency generator and the plasma processing unit. The absolute value |&Dgr;RA| of the difference &Dgr;RA between the AC resistance RA0 at a time t0 and the AC resistance RA1 at a later time t1 and the absolute value |&Dgr;RB| of the difference &Dgr;RB between the AC resistance RB0 at the time t0 and the AC resistance RB1 at the later time t1 are maintained at a value less than an upper limit. Based on these values, whether or not the plasma processing apparatus which is reassembled or used at a user site maintains a required level of performance is evaluated.
    • 等离子体处理装置包括多个等离子体处理单元。 每个等离子体处理单元具有等离子体激励电极,连接到等离子体激励电极的射频发生器和与射频发生器和等离子体处理单元之间的阻抗匹配的匹配电路。 绝对值| DeltaRA | 在时间t0的交流电阻RA0与时间t1之后的交流电阻RA1与绝对值|ΔRB|之间的差值DeltaRA 在时刻t0的交流电阻RB0与后期时刻t1的交流电阻RB1之间的差值ΔRB保持在小于上限的值。 基于这些值,评价在用户现场重新组装或使用的等离子体处理装置是否保持所需的性能水平。
