Incorporating ALD1106 SPICE model in LTspice
dps is a custom diode model used by the NMOS by ALD. My speculation is that they are using N-type substrates, so there will be a junction diode between a NMOS body (presumably p-type well) and a PMOS body (n-type substrate). Therefore pin #5 will be shorted to PMOS's body or, if PMOS is absent in your circuit, the highest voltage rail. 

By finding the string dps in ALL of ALD's library files gave me a few useful matches, that are .model sections. They are in 1108.lib and 11XXYY.lib. They should come from ALD1108xx and ALD2108xx libraries, and all model sections are identical. 

You may download your own library files. I won't show them here. 

Honestly, if all the body terminals of your NMOS and PMOS are always connected to DC voltage rails, I doubt if the additional diodes would make any difference.
