Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conductive patterns are formed on master glass for deposition testing, then deposition pattern inspection is enabled, but the master glass becomes vulnerable to static electricity damage
Solution Approach 1:
The patent applies equipotentiality by electrically connecting all conductive patterns on the master glass through a second conductive pattern and shorting bar, creating an equipotential state that prevents static electricity accumulation and discharge, thereby protecting the master glass from static damage while maintaining the conductive patterns needed for deposition inspection
2Productivity
If master glass is used for preliminary deposition inspection, then process validation is achieved, but frequent replacement is needed due to static damage
Solution Approach 1:
The patent applies preliminary action by pre-forming the second conductive pattern and shorting bar on the master glass before deposition testing, establishing static electricity protection in advance. This preliminary protective measure prevents static damage during subsequent use, eliminating the need for frequent replacements and maintaining continuous inspection productivity

AI summary
There is provided a master glass having a structure capable of preventing damage caused by static electricity. The master glass is a substrate on which a deposition process is experimentally performed by being experimentally loaded loading the master glass into a deposition apparatus before starting the deposition process of the substrate for electronic devices. In one embodiment, a master glass includes first conductive patterns and a second conductive pattern. The first conductive patterns are formed to correspond to a deposition pattern required in a substrate for electronic devices. The second conductive pattern electrically connects all the first conductive patterns to one another.
