Title: Innovations of Ming-Lun Chang
Introduction
Ming-Lun Chang is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 13 patents. His work focuses on improving the efficiency and reliability of metal oxide semiconductors.
Latest Patents
One of his latest patents is a method for forming a self-aligned silicide of a metal oxide semiconductor. This invention discloses a method that includes an ionic implanting step before the self-aligned silicidation process. The implanted ions, such as fluorine, chlorine, bromine, iodine, boron, and trifluroborane, react with the silicon on the surface of the gate structure and the silicon substrate. This reaction creates a barrier effect during silicidation, preventing the spike phenomenon caused by the penetration of cobalt or cobalt silicide into the gate structure or source/drain regions. As a result, junction leakage current and breakdown voltage issues in metal oxide semiconductors are effectively avoided.
Another notable patent is a method for making the bottom electrode of a buried capacitor. This invention protects the non-bottom electrode region with a LPD oxide layer, preventing impurities within the doped Si glass from diffusing into the substrate during annealing. This method effectively reduces the leakage current that is commonly found in conventional buried capacitors.
