Metrology tool for electroless copper thickness measurement for BBUL process development monitoring
Abstract:
A method including measuring a first distance to a surface of an integrated circuit substrate or a portion of an integrated circuit package by measuring an angle to it from two known points; introducing a material onto the surface; measuring a second distance to a surface of the film from the two known points; and determining a thickness of the introduced material by subtracting the second distance from the first distance.
