摘要

PURPOSE: To provide a means to securely prevent a crack and peeling of an insulating film in the periphery of a disconnection part at disconnection of a wiring for a short circuit by etching in substrates for various electronic equipment, such as the substrate for liquid crystal device subjected to a countermeasure against the static electricity by the wiring for the short circuit. CONSTITUTION: In the substrate for liquid crystal device, a hole for cutting 37 for cutting the wiring 33 for the short circuit by etching is provided in a first interlayer insulating film 21 and a second interlayer insulating film 22 which cover the wiring 33 for the short circuit as a static electricity countermeasure wiring. An etching stop layer 38 consisting of a single crystal silicon film having resistance to etching of the second interlayer dielectric 22 is formed over a wider region than the hole for cutting 37 between the wiring 33 for the short circuit and an embedded oxidized film 62.
