hello
Can some one help me in understanding the layout. I am following a video for layout design of inverter. The layout of the PMOS has two squaresi.e. one for drain and source and in the middle is the rectangle i.e. the gate but when I am taking the layout of PMOS from library it has and extra rectangle at the bottom with two square what is the purpose of this bottom rectangle? Can some one help me this? Attached is the PMOS layout taken from library.

In above PMOS the internal colours are also missing I can only see the outlines of the gate drain source but theres no inner colour blue for gate and red for fdrain source. why its not appearing?
