发明名称 SUBSTRATE INSPECTING APPARATUS AND SUBSTRATE INSPECTING METHOD
摘要 PURPOSE: A substrate inspecting apparatus and a substrate inspecting method are provided to evaluate the diverge of a measured resistance value of a wiring pattern by installing an evaluation unit sheet substrate. CONSTITUTION: A sheet substrate is formed by arranging a plurality of unit substrates having a plurality of wiring patterns. The conductivity of the wiring pattern of the unit board is evaluated inside the sheet substrate. A resistance measuring unit(17) measures a resistance value between a measured position on the wiring pattern through first and second inspecting tools. A control unit(11) uses a measurement unit sheet substrate.
