Abstract:
An inspection apparatus for semiconductor devices, comprising:a light irradiation means for irradiating light to a surface of a semiconductor device, the surface carrying external connection terminals formed thereon; an image pickup means for picking up a plane image of the surface of the semiconductor device by using an optical system to provide an image data; an inspection means for inspecting misalignment of tips of the external connection terminals based on the image data; the external connection terminals standing on, and being bonded to, electrode pads of the semiconductor device and being bent into crank forms having respective middle portions extending laterally away from positions of the electrode pads, wherein the external connection terminals have substantially hemispherical roots where the external connection terminals are bonded to the electrode pads of the semiconductor device; and the light irradiation means being positioned such that the surface of the semiconductor device is irradiated from a direction obliquely above the surface of the semiconductor device and generally opposite the direction in which the middle portions of the external connection terminals extend away from the electrode pads, such that only one side of the substantially hemispherical roots of the external connection terminals is irradiated.
