In the crucial step of chip manufacturing - non-destructive testing of wafers, even a slight deviation in precision can significantly reduce the yield of chips! And ZHHIMG® granite is like installing a "stabilizer" on the testing equipment, making the test results fast and accurate!
Why is it so powerful? First of all, ZHHIMG® granite is "heat-resistant"! Ordinary materials are prone to thermal expansion and contraction when exposed to temperature changes, causing deformation and affecting the detection accuracy. However, the coefficient of thermal expansion of ZHHIMG® granite is extremely low. Even if the ambient temperature changes, its size will hardly change, and the error can be controlled within a few tens of the diameter of a human hair!
Secondly, its "physique" is extremely sturdy! The Mohs hardness reaches 6.5, and its wear resistance is three times that of ordinary steel. During the detection process, even if the equipment moves frequently and the probe comes into repeated contact, its surface will not wear out and always remains in an extremely flat and stable state, providing a precise "stage" for the detection equipment.
Even more amazing is that ZHHIMG® has adopted "black technology"! After 48 hours of special annealing treatment, the "temper" inside the stone was ground to be extremely stable. The built-in microchannel water cooling system is like installing a "small air conditioner" on the base, cooling down where it gets hot and further reducing deformation.
Let the data speak for itself! After a major chip manufacturer adopted ZHHIMG® granite, the detection error of wafer surface roughness was reduced by 75%, and the defect location accuracy was improved by nearly 80%! Moreover, each piece of ZHHIMG® granite comes with an "ID card" - a vein traceability report and a professional inspection certificate. The quality is reliable and visible!
Want wafer inspection to be both stable and accurate? ZHHIMG® granite is your "secret weapon"!
