摘要:
An apparatus includes a first device with a metal gate and a drain well that experiences a series resistance that drops a drain contact voltage from 10 V to 4-6 V at a junction between the drain well and a channel under the gate. The apparatus includes an interlayer dielectric layer (ILD0) disposed above and on the drain well and a salicide drain contact in the drain well. The apparatus also includes a subsequent device that is located in a region different from the first device that operates at a voltage lower than the first device.
