Abstract
Description
本発明は、日本国特許出願:特願2008-025445号(2008年 2月 5日出願)の優先権主張に基づくものであり、同出願の全記載内容は引用をもって本書に組み込み記載されているものとする。

以下の分析は、本発明の観点から与えられる。
ところで、半導体ウェハの検査では、被検査チップの縮小化や複雑化等に伴い検査コストの増加が問題となっている。検査コストを削減する1つの方法として、同測数を増やすことで、1チップ当たりの検査時間を削減することである。しかしながら、従来の手法では、1回で検査できる半導体ウェハが1枚に限られ、1枚の半導体ウェハに形成されたチップ数を超えた数のチップを同時に検査することができないため、1チップ当たりの検査時間を短縮するのに限界があった。また、複数の半導体検査装置を並列に稼動することによって同時に検査できるチップ数を増加させることができるが、これでは半導体検査装置の増設によってコストの増加を招いてしまう。
