IV characteristics and layout of NMOS and PMOS devices

LAB WORK

By following tutorial 2 we will create I-V curves for NMOS and PMOS devices.

We will start by creating the schematics we will use for the NMOS and PMOS devices. The width is 6u and length 600n.

Then we proceed to create the layout for the NMOS and PMOS devices. We also DRC to check there are no errors.

 After creating the layout we will LVS the schematic with the extracted view.

Then we create the probe pads (metal 3 (75ux75u) with overglass (63ux63u))

Now we create the layout connecting the probe pads to the NMOS and PMOS

We proceed to DRC and LVS

Now we will simulate the 3-terminal and 4-terminal NMOS and PMOS
