Patent ID: 8143105

Claim:
A method comprising: depositing a thick layer of a first nonmetallic material over a semiconductor wafer, the first nonmetallic material comprising a brittle material; depositing a thin layer of a second nonmetallic material over the thick layer, the second nonmetallic layer comprising an amorphous moisture-barrier material; selectively removing a second portion of the thick layer to define a singulation street between a first die of the wafer and a second die of the wafer while leaving a first portion of the thick layer over the first die; and cutting the wafer along the singulation street to separate the first die from the second die, wherein the cutting the wafer along the singulation street includes retaining a first portion of the thin layer between the first portion of the thick layer and a kerf defined by the cutting the wafer, wherein the first portion of the thin layer encapsulates the first portion of the thick layer.
