Patent ID: 7446010

Claim:
A method for forming a metal/semiconductor/metal(MSM) back-to-back Schottky diode from a silicon (Si) semiconductor, the method comprising: depositing an amorphous Si (a-Si) semiconductor layer between a bottom electrode and a top electrode with a DC sputtering process as follows: using a Si target; sputtering with a power in the range of about 100 to 300 watts (W); heating a substrate to a temperature of about 20° to 200° C.; creating a deposition pressure in the range of about 7.0 to 9 mtorr; using an atmosphere of Ar; depositing for a duration in the range of about 7 to 150 minutes; and, forming a-Si; forming a MSM diode having a threshold voltage, a breakdown voltage, and an on/off current ratio; and, modifying the threshold voltage, the breakdown voltage, and the on/off current ratio of the MSM diode in response to controlling a thickness of the Si semiconductor layer.
