Especially for advanced semiconductor technologies, it is expected some of the chips on each manufactured wafer contain defects that render them non-functional. The primary objective of testing is to find and separate those non-functional chips from the fully functional ones, meaning that one or more responses captured by the tester from a non-functional chip under test differ from the expected response. The percentage of chips that fail test, hence, should be closely rel… WebApr 11, 2024 · The electrochemical reduction of CO2 is an efficient method to convert CO2 waste into hydrocarbon fuels, among which methanol is the direct liquid fuel in the …
