摘要:

基于一个典型的013 μm绝缘体上硅,射频开关电路工艺流程,分析了离子掺杂工艺流程对射频开关导通电阻Ron和关断电容Coff的影响。通过N型MOS管的浅掺杂注入后热退火温度和N型MOS管浅掺杂能量的分批实验,证实了退火温度可影响射频开关的导通电阻和关断电容。进一步实验结果显示,浅掺杂注入的砷(As)和磷(P)注入的剂量是主导因素,各自对导通电阻和关断电容值的影响均为线性且趋势相反,为基于013 μm SOI的射频开关性能的优化提供了依据。

Abstract:

Based on a typical 013 μm RF Switch SOI technics flow, analyze the effect of NLDD (NMOS Lightly Dropped Drain) technics to switch of Ron and Coff. Based on the experiment result of NMOS NLDD RTA and further discuss to NMOS NLDD IMP, proved RTA can effect Ron and Coff. The result shows dose of As and P acted as main effector to the research, present a regular linear trend to Ron and Coff which share an inverse tendency, thus providing a reference of RF switch optimizing method based on 013 μm SOI technic.

Key words: SOI, RF switch, insertion loss, isolation, doping energy, dose
