圆面积

Do you know how to calculate the area of a circle?

你知道怎样计算圆的面积吗？

Finally, a two-mask process was attempted to extend the same concept of the chip process. Here the mask of the contact aperture was replaced by the mask of the LED pad. After etching the SiO2 and ITO in the aperture region, a lateral etch of SiO2 was made to increase the ITO contact area. Although the forward voltage of the GaN LED shows a normal value, the process yield is still low and requires further study.

二道光罩制程延伸了三道光制程的理念，只是因为透明导电层的圆孔图形，是用电极的光罩去开的，所以蚀刻完二氧化矽膜及氧化铟锡膜后，必须再做二氧化矽膜的回蚀刻，让二氧化矽再内缩进去，以增加氧化铟锡和电极的接触面积，不会造成发光二极体的顺向电压提高，但因制程良率太低，所以还须要继续研究改善。

AI:The area of a circle is pi times the radius squared.

這貨它嗎的居然說：圆的面积皮倍，半径的平方。
