Patent ID: 7132683

Claim:
An integrated circuit comprising a metal oxide semiconductor transistor, and an associated test structure for testing to analyze one or more characteristics of the metal oxide semiconductor transistor, the metal oxide semiconductor transistor comprising: a channel of a first semiconductor type, a drain of a second semiconductor type adjacent to a first side of the channel, a source of the second semiconductor type adjacent to a second side of the channel opposite the first side of the channel, an insulator over the channel, and a gate on the insulator; and the test structure comprising: a test structure channel of the first semiconductor type, a test structure drain of the first semiconductor type adjacent to a first side of the test structure channel, a test structure source of the first semiconductor type adjacent to a second side of the test structure channel opposite the first side of the test structure channel, an insulator over the test structure channel, and a test structure gate on the test structure insulator, wherein a test parameter measurable on the test structure closely corresponds to a parameter of the metal oxide semiconductor transistor.
