Description
本実施形態の検査装置10は、例えば図1に示すように、被処理体(例えば、半導体ウエハ)Wを載置する載置体11と、載置体11と循環配管12を介して接続され且つ載置体11内へ冷媒を循環させるポンプ13と、ポンプ13を介して載置体11から循環配管12を循環する昇温後の冷媒を元の温度まで冷却する冷凍機14の第1熱交換器14Aと、を備え、載置体11の内部へ冷媒を循環させて、載置体11上の半導体ウエハWを冷却して所定の温度で半導体ウエハWの電気的特性検査を行うように構成されている。載置体11は、検査の際に、半導体ウエハWとプローブカード(図示せず)とを接触させるために水平方向及び上下方向に移動するようになっている。
本実施形態の検査装置10Aは、例えば図2に示すように、循環配管12に配置された低温冷媒タンク15と、この低温冷媒タンク15の上流側及び下流側の双方に配置された第1、第2ポンプ13A、13Bと、を備えている以外は、第1の実施形態と実質的に同様に構成されている。従って、水分除去装置20は、図1に示すものと同一の機能を果たすため、第1の実施形態と同一部分または相当部分には同一符号を付し、その説明を省略する。
本実施形態の検査装置10Bは、例えば図3に示すように、載置体(図示せず)に冷媒を循環させる循環配管12と、循環配管12に配置された低温冷媒タンク15と、この低温冷媒タンク15の上流側及び下流側の双方に配置された第1、第2ポンプ13A、13Bと、第1ポンプ13Aと冷温冷媒タンク15の間に配置された冷凍機14及び水分除去装置20と、を備え、第2の実施形態に準じて構成されている。従って、第2の実施形態と同様に、第1ポンプ13Aによって低温冷媒タンク15内の冷媒を吸引して低温冷媒タンク15へ戻す間に、冷凍機14が冷媒を冷却すると共に水分除去装置20が冷媒の一部から水分を除去する。
