The lens holding part holds the solid immersion lens so that light emerging from the solid immersion lens to the base part side travels through a region outside the lens holding part and toward the base part, and the base part has a light passing portion 53 which transmits the light toward the objective lens. Since the lens holding part extends in the direction of the optical axis L of the objective lens, even in a case where an observation object 11 is observed as located on a bottom surface of recess 13, the lens holding part will be prevented from contacting a side wall 13 a of the recess. As a result, it becomes feasible to observe the observation object up to a region closer to the vicinity of peripheral part 11 a of the observation object. This provides a solid immersion lens holder allowing observation up to a region closer to a peripheral part of an observation object even in a case where the observation object is set in a recess of a sample.
SUMMARY OF THE INVENTION However, if the solid immersion lens is held by the solid immersion lens holder of the tapered shape with the solid immersion lens at the top as in the semiconductor inspection system described in Document 1, there will arise a problem as described below, where an IC (semiconductor device) as an observation object is housed in a socket or where a mold IC package having an IC molded with resin is inspected.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a configuration diagram of a semiconductor inspection apparatus to which an embodiment of the solid immersion lens holder according to the present invention is applied.
DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the solid immersion lens holder according to the present invention will be described below with reference to the drawings. The same elements will be denoted by the same reference symbols in each of drawings, without redundant description.
First Embodiment FIG. 1 is a configuration diagram showing a semiconductor inspection apparatus provided with the solid immersion lens holder according to the first embodiment of the present invention. FIG. 2 is a configuration diagram showing a configuration of the solid immersion lens holder. FIG. 3 is an exploded perspective view of the solid immersion lens holder. FIG. 4( a) is a sectional view along line IV-IV in FIG. 3, and FIG. 4( b) an enlarged view of an end portion of a lens holding part in the solid immersion lens holder shown in FIG. 4( a). FIG. 2 shows a state in observation of a sample while the solid immersion lens holder is mounted on an objective lens. FIGS. 3, 4(a), and 4(b) show a state in which the solid immersion lens holder holds a solid immersion lens. FIG. 4( b) shows a state in which the solid immersion lens is pressed against an observation object.
The �mold semiconductor device� is a device in which the semiconductor device 11 is hermetically sealed as molded with resin 12. The �internal information� includes a circuit pattern of the semiconductor device and very weak emission from the semiconductor device. Examples of this very weak emission include emission from an abnormal part based on a defect of the semiconductor device, transient emission with a switching operation of a transistor in the semiconductor device, and so on. Furthermore, the very weak emission also includes heat generated based on a defect of the semiconductor device.
Second Embodiment FIG. 5 is a bottom view of solid immersion lens holder 8B according to the second embodiment. FIG. 5 shows a state in which the solid immersion lens holder 8B holds a solid immersion lens 6.
Third Embodiment FIG. 6 is a bottom view of solid immersion lens holder 8C according to the third embodiment. FIG. 6 shows a state in which the solid immersion lens holder 8C holds a solid immersion lens 6.
Fourth Embodiment FIG. 7 is an exploded side view of solid immersion lens holder 8D according to the fourth embodiment. FIG. 7 shows a state in which the solid immersion lens holder 8D holds a solid immersion lens 6.
Fifth Embodiment FIG. 8 is a bottom view of solid immersion lens holder 8E according to the fifth embodiment. FIG. 9 is a sectional view along line IX-IX in FIG. 8. FIGS. 8 and 9 show a state in which the solid immersion lens holder 8E holds a solid immersion lens 6.
Sixth Embodiment FIG. 10 is an exploded perspective view of solid immersion lens holder 8F according to the sixth embodiment. FIG. 10 shows a case in which the solid immersion lens holder 8F holds a solid immersion lens 6.
Seventh Embodiment FIG. 11 is a view of solid immersion lens holder 8G according to the seventh embodiment, from the side of objective lens 21. FIG. 12 is a sectional view along line XII-XII in FIG. 11. FIG. 13 is a view of the solid immersion lens holder 8G from a direction of arrow A2 in FIG. 12. FIGS. 11 to 13 show a state in which the solid immersion lens holder 8G holds a solid immersion lens 6.
