Latest Patents

One of Yu-Chun Chen's latest patents is a metrology tool for electroless copper thickness measurement for BBUL process development monitoring. This method involves 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. The process includes introducing a material onto the surface, measuring a second distance to the surface of the film from the two known points, and determining the thickness of the introduced material by subtracting the second distance from the first distance. Another significant patent is for a photosensitive sacrificial polymer with low residue. This invention relates to PAG bilayer and PAG-doped unilayer structures using sacrificial polymer layers that incorporate a photoacid generator with a concentration gradient. The PAG concentration is higher in the upper portion of such structures than in the lower portion. This patent also covers methods for using these bilayers and unilayers to form microelectronic structures with three-dimensional space and methods for decomposing the sacrificial polymer within these layers.
