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… WebDesign DFT/DV Engineer Intern (4562) Overview Of Role You will be part of the DFT and verification team responsible for all logic test chips designed at TSMC for yield learning in advanced process ...
