Patent ID: 8853022

Claim:
A method of forming a device comprising: providing a substrate having a device region, wherein the device region comprises a source region, a gate region and a drain region defined thereon; forming a device well having device dopants of a device dopant concentration; forming a drift well in the substrate between the gate region and drain region, wherein the drift well encompasses the drain region and underlaps a portion of the gate region and creates a gate overlap region O gate in the drift well; the device well and drift well form a device and drift well (DDW) interface in the substrate in the gate region; forming a gate on the substrate on the gate region, the gate includes first and second gate portions, wherein an interface of the first and second gate portions is at the DDW interface; implanting gate dopants to dope the first gate portion with the gate dopants, wherein the first gate portion has a different dopant concentration of gate dopants than the second gate portion; and forming a source and drain in the source region and drain region, wherein the drain is separated from the gate on a second side of the gate and the source is adjacent to the first side of the gate, wherein a channel of the device is disposed under the gate from the source to the DDW interface.
