Abstract: A semiconductor arrangement and method of formation are provided. A method of semiconductor formation includes using a single photoresist to mask off an area where low voltage devices are to be formed as well as gate structures of high voltage devices while performing high energy implants for the high voltage devices. Another method of semiconductor fabrication includes performing high energy implants for high voltage devices through a patterned photoresist where the photoresist is patterned prior to forming gate structures for high voltage devices and prior to forming gate structures for low voltage devices. After the high energy implants are performed, subsequent processing is performed to form high voltage devices and low voltage devices. High voltage device and low voltage devices are thus formed in a CMOS process without need for additional masks.
