Abstract
A product specific test mask is used to analyze circuit yield and associate it with device parameter yield, which can then more easily be related to process failure. Once a consistent failure mode has been identified, it is found that a problem specific test mask is also required to finally effect a solution. An example of this yield diagnosis methodology is described based on a nonvolatile static RAM (SRAM) circuit
