Latest Patents

One of his latest patents is titled "Bonding pad structure to prevent inter-metal dielectric cracking and to improve bondability." This invention involves a process for forming a bond pad structure with a roughened top surface topography. The innovation aims to enhance the bondability of gold wire bonds to the underlying bond pad structure. The process utilizes a tungsten mesh pattern formed in an inter-metal dielectric (IMD) layer, which is located beneath the bond pad structure. This design reduces the bonding force experienced during the gold wire bond procedure, ultimately improving the bondability.

Another significant patent by Chun-Hung Lu is "Method and apparatus for CMP end point detection using confocal optics." This invention employs confocal optics to enhance the signal-to-noise ratio during the end point detection of a chemical mechanical polishing (CMP) process on semiconductor wafers. The use of confocal optics allows for greater selectivity when intermediate layers of metal are present in the wafer. A laser diode serves as the light source, examining the wafer surface and sensing reflected light to determine the end point of the CMP process.
