In a machine for the production of micro-electronic wafers (a component of semiconductor materials such as integrated circuits, transistors and diodes) the temperature increased considerably during the production process. This led to a decrease in the quality of the product. A complex and lengthy journey to adapt the hardware could have offered a solution. But LIME approached the issue from a different perspective.
With our knowledge of mathematics and multiphysics, LIME created insight into the dynamic thermal effects.
On the basis of this insight, LIME developed a model that calculates within 12 milliseconds how the machine should be fine-tuned. This way deviations in the product as a result of the increase in heat of the machine during production are continually corrected.
Thanks to this method the accuracy of the wafer machine is now twice as high and the throughput speed increased.
The results were so positive that the client applied for a patent for this Mathware.
