Latest Patents

Among his latest inventions, Karl-Josef Kramer has developed methods for forming silicide regions on silicon bodies. One notable patent outlines a method for producing a silicide region that reduces electrical contact resistance in integrated electronic devices. This method involves creating an amorphous region on a silicon body using ion implantation and subsequently forming a metal layer, such as titanium, cobalt, or nickel, in contact with this region. The innovative process utilizes intense light, like that from a laser, to diffuse metal atoms into the amorphous area, thus creating an alloy with silicide composition.

Another significant patent focuses on forming silicide contacts to a MISFET (Metal-Insulator-Semiconductor Field-Effect Transistor) device. The method entails establishing field isolation layers to isolate silicon substrate sections and developing gate, source, and drain regions. The process includes selective irradiation of the metal layer to melt parts of the gate and active regions, converting them into silicide alloys while maintaining the structural integrity of the remaining substrate. This approach not only improves device efficiency but allows for more controlled silicidation rates between the gate and source/drain regions.
