Abstract
The electrical behaviour of the parasitic Al-gate MOS transistor on LOCOS and SILO isolation structures is investigated. The influence of the two-dimensional parasitic channel on the isolation performances is pointed out by studying the bird´s-beak length, the field oxide thickness, and the use of a semi- or fully recessed structure. The measured characteristics are discussed and explained with the assistance of the two-dimensional process simulations of the isolation structures.<>
