摘要 提高 LDMOS的一个关键步骤是加场极板以降低其表面击穿电压。文中分析了加场极板后的 LDMOS击穿电压模式 ,指出了场极板的分压作用和场极板边界的影响 。 In order to impro ve the breakdown voltage of a high-volta ge LDMOS,the field plate structure must be used.The paper has given a breakdown voltage model for a high-voltage LDMOS a fter adding a field plate.We have gotten relationships between the breakdown vol tage and field plates sizes.From this analys is,a suitable breakdown voltage expressi on is obtained.Finally,the theo retical prediction is well verified by e xperimental data.
