Title: Alexander Hanke: Innovator in Semiconductor Technology
Introduction
Alexander Hanke is a prominent inventor based in Radebeul, Germany. He has made significant contributions to the field of semiconductor technology, holding a total of 4 patents. His innovative work focuses on enhancing the efficiency and reliability of semiconductor devices.
Latest Patents
One of Hanke's latest patents is a semiconductor device comprising a copper alloy as a barrier layer in a copper metallization layer. This invention involves forming a tin and nickel-containing copper alloy on an exposed copper surface, which is treated to have a copper oxide. This process provides a reliable and highly efficient capping layer. The alloy is formed in a gaseous ambient using tin hydride and nickel, carbon monoxide in a thermally driven reaction.
Another notable patent is a technique for forming nickel silicide by depositing nickel from a gaseous precursor. In this method, nickel silicide is formed using a gaseous precursor, such as nickel tetra carbonyl. The equilibrium of the decomposition of this gas can be controlled to achieve a highly selective nickel silicide formation rate. This approach eliminates the need for an etch step to remove excess nickel, as only minute amounts of nickel form on exposed surfaces. Consequently, this results in reduced process complexity, enhanced controllability, and improved tool lifetime.
