镀锡的

A three-mask chip process was first attempted in this work, where the 3rd mask was designed to evaporate the identical metal films for p- and n-pads. However, it was found that the Cr film showed inferior adhesion property on the ITO current spreading layer after the peeling test. In order to overcome this problem, a contact aperture was opened in the mask of ITO layer.
