MOSFET device having denuded zones for forming alignment marks

A process for fabricating MOSFET devices, in which a denuded zone in silicon has been created during the normal process sequence, has been developed. In order to avoid the formation of deleterious oxygen precipitates, prior to the creation of the denuded zone, low temperature processing had to be us...
