Abstract:
A device and a method for forming a device are disclosed. The method includes providing a substrate prepared with a device region. A device well having second polarity type dopants is formed in the substrate. A threshold voltage (V T ) implant is performed with a desired level of second polarity type dopants into the substrate. The V T  implant forms a V T  adjust region to obtain a desired V T  of a transistor. A co-implantation with diffusion suppression material is performed to form a diffusion suppression (DS) region in the substrate. The DS region reduces or prevents segregation and out-diffusion of the V T  implanted second polarity type dopants. A transistor of a first polarity type having a gate is formed in the device region. First and second diffusion regions are formed adjacent to sidewalls of the gate.

Claim (Index 12):
A device comprising:\n a substrate prepared with a device isolation region, wherein the device isolation region surrounds a device region in the substrate; a device well disposed in the substrate in the device region, wherein the device well includes second polarity type dopants; a transistor, wherein the transistor comprises a gate disposed on the substrate and first and second source/drain (S/D) regions disposed within the device well adjacent to first and second gate sidewalls, wherein the first and second S/D regions comprise first polarity type dopants; a channel region of the transistor, the channel region is disposed in the substrate below the gate and between the first and second S/D regions; and a diffusion suppression (DS) region comprising carbon is disposed in the channel region and adjacent to the device isolation region, wherein the DS region extends laterally through the channel region and into the first and second S/D regions.
