I/O Process Optimization to Cover Wide Range Operation Voltage

Abstract

A process has been developed to cover wide range I/O operation voltage (1.8V to 3.3V) without changing the 3.3V I/O library at author's organization to meet the market demand by optimization of 3.3V process. The main emphasis is given on to improve the Idsat current from the baseline and maintain the Ioff comparable as 3.3V process. This process passed all device level reliability test. This process is used to fabricate wide range I/O operation voltage device at author's organization.
