Abstract:
1. A suction unit to be used for a semiconductor device observation apparatus for performing observation of a semiconductor device by use of a solid immersion lens, comprising: a main body portion having a first surface on which a semiconductor wafer formed with the semiconductor device is arranged and a second surface that is a surface opposite to the first surface, and in which a through-hole that penetrates through the first surface and the second surface is formed; and a light transmitting portion having a light incident surface onto which light from the semiconductor device is made incident and a light emitting surface from which light made incident from the light incident surface is emitted, and which is fitted to the through-hole so that the light incident surface is exposed to a side of the first surface and the light emitting surface is exposed to a side of the second surface, wherein in the first surface, a first suction groove for vacuum sucking the semiconductor wafer to fix the semiconductor device to the light incident surface is formed, and in the second surface, a second suction groove for vacuum sucking the solid immersion lens to fix the solid immersion lens to the light emitting surface is formed.
