Abstract:
1. A probing apparatus for probing a micro signal from a measured device on an insulated substrate that mounts a plurality of devices spaced apart from each other, comprising: a stage defining an upper surface that supports a lower surface of the insulated substrate and is connected to a ground terminal, wherein the upper surface defines a first outer periphery; a probe that inputs or outputs a measuring signal to or from a measurement terminal of the measured device; and a shielding cover that is positioned over an upper surface of the measured device and is connected to the ground terminal, wherein the shielding cover forms a shielding gap between the shielding cover and the stage, the measured device is disposed in the shielding gap, the shielding cover has an opposed surface defining a second outer periphery, and a largest dimension of the second outer periphery is smaller than a smallest dimension of the first outer periphery.
