摘要:
A semiconductor device with a high-strength porous modified layer having a pore size of 1 nm or less, which is formed, in a multilayer wiring forming process, by forming a via hole and a wiring trench in a via interlayer insulating film and a wiring interlayer insulting film and then irradiating an electron beam or an ultraviolet ray onto the opening side walls.
