Simulation Analysis of FP FLR Planar Junction Termination

FP-FLR结终端结构的模拟分析

PRA provided a proactive and effective approach for implementation of FLR and could embodies the public participation of FLR theory .

PRA方法为实施森林景观恢复提供了一个主动而有效地途径，是一种适用于FLR、充分体现FLR中公众参与的方法。

In order to adapt this method to practical device manufacture we investigate the design method of offset FP structure that is the combination of FLR structure and FP structure .

为了使这种结构适用于实际生产，我们又研究了场限环加场板的复合结构&偏移场板结构的设计方法。

The field limitting ring ( FLR ), behaved as a compatible planar junction termination , has been widely used in many high voltage devices .

场限制环作为一种可与许多器件工艺相容的PN结终端得到了广泛应用。

As a vehicle for delivering on internationally agreed commitments on forests , biodiversity , climate change and desertification , FLR has got broad attention internationally .

作为履行国际上在森林、生物多样性、气候变化和荒漠化方面各项商定承诺的一个途径，森林景观恢复在国际上已经受到了广泛的关注。

Forest landscape restoration ( FLR ) is a process that aims to regain ecological integrity and enhance human wellbeing in deforested or degraded forest landscapes .

森林景观恢复（FLR）是一个过程，旨在恢复采伐迹地或退化森林景观的生态完整性，提高人类福利。

There are two parts in the work of this thesis : researches on field-limiting ring ( FLR ) termination structure and field plate ( FP ) termination structure .

本文的工作分为两部分：场限环（FLR）终端结构和偏移场板（FP）终端结构的研究。

According to the shortcoming of FLR ( Field Limiting Ring ) and FP ( Field Plate ), this paper presents a mixed termination structure about FLR and FP .

针对常规采用的场限制保护环法和场板法高压终端结构的缺陷，本文提出了场板混合终端结构。

The applicability of the methodology is also investigated in a wide scope , which shows that the methodology has a very good performance in the medium-voltage-range FLR termination design .

我们在广泛范围内对这一方法的适用性进行了研究，结果表明这一方法在中等电压范围的FLR终端设计中非常有效。

With offset FP structure obtained by using our method the device breakdown voltage is higher than FLR structure , and this structure can screen the influence of interface charge in part and improve the stability of device performance .

用我们的方法设计的偏移场板结构不仅比场限环结构提高了击穿电压，而且部分地屏蔽了界面电荷对器件击穿电压的影响，提高了器件工作性能的稳定性。

Three forming mechanisms that give rise to the FLR can be concluded as climate change , structural uplift and basement differential subsidence in gentle slope caused by episodic movements of boundary faults . They can also lead to the falling of the relative lake-level in rift basin .
