Abstract
The present invention supplies a manufacturing method of a semiconductor device, which includes a non-contact inspection process capable of confirming if a circuit or circuit element formed on an array substrate is normally performed and can decrease a manufacturing cost by eliminating wastes to keep a defective product forming.
An electromotive force generated by electromagnetic induction is rectified and shaped by using primary coils formed on a check substrate and secondary coils formed on an array substrate, whereby a power source voltage and a driving signal are supplied to circuits or circuit elements on a TFT substrate so as to be driven.
