WebJan 1, 2024 · Theoretically, dropping invalid (pattern that can make the test pass) test patterns can reduce test cost. In fact, When the valid (pattern that can make the test fail) and invalid patterns overlap seriously, identifying effective patterns performs poorly, which will not achieve the expected results. This paper proposes a kind of eliminate ... Webtures have led the industry to consider double patterning lithogra-phy. The transition from 248nm to 193nm wavelength lithography sources has been cost effective; however, the transition from 193nm to 157nm or EUV sources seems more costly than double pattern-ing using a 193nm source.
