Semiconductor fabs and OEMs value the accuracy, precision and versatility of the WaferSense and ReticleSense measurement portfolio to enable improvements in fab yields and equipment uptime.
A method for extracting wafer-to-wafer thickness variation from interferometry signals off patterned (product) wafer polish during non-endpointed CMP. The method includes sensing sample signals representing polishing trace from product wafers near the end of polishing period from at least two product ...
The ability to measure flatness, thickness, and thickness variation of 300 millimeter glass and silicon wafers is critical for successful integration of 3DIC assemblies. Traditional contact probes or conventional interferometry systems are too slow or do not have the necess...
MSP, a Division of TSI, supplies wafer contamination standards and reticle contamination standards in the semiconductor industry for consistent and repeatable particle size and count control.
Devicewafer减薄,目前Device+carrier总厚度可减薄到100um,Devicewafer Grinding要求wafer表面TTV(TotalThickness Variation)小于±0.1um,wafer center均匀性较好,waferedge均匀性稍差;WTW(waferto wafer)每片grindingwafer与wafer之间的差异<±0.025um; 3.2.4PAD opening ...
is the surface, the stronger is the wafer. The smooth surface will help preventing breakage during the wafer demounting and solvent cleaning. It is very important to do polishing instead of wet etching process in the wafer thinning operation to minimize the thickness variation, and reduce the su...
Methods of wafer-to-wafer bonding are disclosed. These methods use a force-transposing substrate providing redistribution of the applied force to the local bonding areas across the wafer. Certain vers
The curves are shifted to the left after APTES treatment, which induces positive charges, and to the right once the nanoparticles have been attached. The variation of the flat-band voltage and/or threshold voltage are used to determine the areal density of electrons in nanoparticles: N≃Δ...
