Patent attributes
A fabricating method of wafer protection layers and a wafer structure are provided. The fabricating method includes providing a wafer first. The wafer includes pluralities of chips and has an active surface, a corresponding reverse surface and a plurality of pre-cut trenches on the active surface. On the active surface, pluralities of bumps are disposed. Next, a first curing-type protection layer and a pellicle are disposed over the active surface. Afterwards, the first curing-type protection layer is asked to contact the active surface. Besides, a second curing-type protection layer is disposed on the reverse surface. Afterward, the first and the second curing-type protection layer are cured. Finally, the wafer is cut through the pre-cut trenches to separate the chips from the wafer.
