  • Patent number: 9279673
    Abstract: A warpage test system uses a calibration block to calibrate the warpage test system over a temperature profile. The calibration block includes a first metal block bonded to a second metal block. The first metal block includes a first metal and a second different metal. The first metal block includes a CTE different than a CTE of the second metal block. The calibration block is disposed in the warpage test system. A warpage of the calibration block is measured over a temperature profile ranging from 28° C. to 260° C. A deviation between the measured warpage of the calibration block and a known thermal expansion of the calibration block over the temperature profile is recorded. The warpage measurement in a semiconductor package is compensated by the deviation between the measured warpage of the calibration block and the known thermal expansion or warpage of the calibration block over the temperature profile.

  • Publication number: 20130256840
    Abstract: A semiconductor device has a build-up interconnect structure formed over an active surface of a semiconductor wafer containing a plurality of semiconductor die separated by a saw street. An insulating layer is formed over the interconnect structure. Bumps are formed over the interconnect structure. A protective coating material is deposited over the insulating layer and saw street. A lamination tape is applied over the coating material. A portion of a back surface of the semiconductor wafer is removed. A mounting tape is applied over the back surface. The lamination tape is removed while leaving the coating material over the insulating layer and saw street. A first channel is formed through the saw street extending partially through the semiconductor wafer. The coating material is removed after forming the first channel. A second channel is formed through the saw street and the mounting tape is removed to singulate the semiconductor wafer.
