Full adder accepts three one bit and generates a sum and carry out. Whereas half adder as accepts only two one bit to generate sum and carry.

Half adder does not have input to handle carry from the previous lower significant position(previous stage) where as the full adder takes into account the carry from the previous stage.

We need carry at output to minimize the propagation delay
