台面结构 meaning in English

mesa structure

On the base of the study on si / sige hetero - junction fast switching power diode , two kinds of novel structure of sige / si pin diode are proposed in abstract this paper . the one is the gradual changing doping concentration in the n - region , and the other is sige pin diode with mesa structure
本文在对sige si异质结快速开关功率二极管的研究基础上，提出了两种sige si快速开关功率二极管的新结构： ?基区渐变掺杂型sige异质结开关功率二极管和台面结构sige异质结开关功率二极管。
The researching results indicate that using the two kinds of novel structure , the fast - switching and the soft recovery characteristics of the device are much improved but not notable changed in forward drop , and the temperature characteristic is improved , too . most of the characteristics are far better than the normal pin diode structures
研究结果表明，在采用?基区渐变掺杂和台面结构后的p ~ + ( sige ) - n ~ - - n ~ +异质结中，我们得到了更快而软的反向恢复特性，和更低通态压降的正向导通特性，且温度特性也有明显改善。
