A semiconductor inspection device for inspecting an electronic device is
disclosed. The semiconductor inspection device includes a contact probe
including a plurality of column parts disposed in continuation, each of
the column parts having different height, a conductive layer formed at
least on the surfaces of the column parts, a holding part for holding the
contact probe, and a through-hole electrode penetrating at least one of
the column parts, wherein the contact probe and the holding part are
integrally formed from a single silicon substrate.
