摘要:
A semiconductor chip inspection apparatus largely reduces occurrence of damage due to foreign matter in an inspection process and improves durability at the same time of miniaturization is provided. As to a highly accurate thin-film probe sheet which performs: a contact to electrode pads arranged at a narrow pitch and a high density along with integration of semiconductor chip; and an inspection of semiconductor chips, by providing two layers of metal films selectively removable in a step-like shape in a periphery region of fine contact terminal having sharp tips and arranged at a high density and a narrow pitch at the same level as electrode pads, an upper periphery of the contact terminals is covered with an insulating film, and a large space region is formed.
