Latest Patents

Among his latest patents is a groundbreaking invention focused on a semiconductor device and method of manufacturing it. This patent outlines a process where a plug electrode undergoes etch back to remain within a contact hole, thereby exposing a barrier metal on the top surface of an interlayer insulating film. The process further details that the barrier metal is subjected to additional etch back, which exposes the top surface of the insulating film. Following this, remaining element structures are formed. To optimize the semiconductor lifetime, irradiation with helium or an electron beam is employed, followed by hydrogen annealing. Notably, during this annealing, the absence of the barrier metal allows hydrogen atoms to access the mesa section, facilitating recovery from lattice defects that result from earlier irradiation. Ultimately, this innovation enables the stable achievement of predetermined characteristics in semiconductor devices, enhancing efficiency and reliability.
