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。

For this reason, a novel PPOP was designed and prepared using two side drilling technology and water-insoluble drug gliclazide was employed as model drug. Influencing factors from six aspects were studied which was drug layer formulation, push layer formulation, coating formulation, orifice properties, tableting art and dissolution conditions, respectively, and the difference between the dissolution profiles of novel PPOP and conventional PPOP was also evaluated by similarity factor (f_2). Through determination of the viscosity of drug layer and push layer of the novel PPOP, the mechanism of drug release from novel PPOP was discussed by the help of Poiseuilles law of laminar flow.
