WebThe semiconductor chip devices used in hybrid assembly are purchased with a passivation layer of either silicon nitride or silicon dioxide. These coatings are applied by the manufacturer at the wafer stage as one of the last steps in the fabrication of devices. They are applied by evaporation, sputtering or chemical vapor deposition, to the ... WebThis applies tensile stress to the internal crack state of the wafer and extends the cracks to the top and bottom surface, separating the wafer. Since wafer separation is performed by extending cracks, there is no stress on the device. Furthermore, since there is fundamentally no kerf loss, this can lead to an improvement of chip yield.
