The lapping process involves thinning wafers from the back with a rotating abrasive surface. It is important to receive precise feedback as the process is carried out to monitor the quantity of ...

During lapping, a spinning abrasive surface is used to thin wafers from the backside. As the process progresses, precise feedback is required to monitor the amount of material removed and determine ...

Semiconductors guarantee high resistance, low cost, and reliability when used in electronic circuits. To manufacture semiconductor devices, multiple photographic and chemical-processing steps are ...

The shift from planar SoCs to 3D-ICs and advanced packages requires much thinner wafers in order to improve performance and reduce power, reducing the distance that signals need to travel and the ...
