Abstract:
An integrated circuit device having insulated gate field effect transistors (IGFETs) having a plurality of horizontally disposed channels that can be vertically aligned above a substrate with each channel being surrounded by a gate structure has been disclosed. The integrated circuit device may include electrostatic discharge (ESD) protection circuit structures. The ESD protection circuit structures may be formed in regions other than the region that the IGFETs are formed as well as in the region that the IGFETs having a plurality of horizontally disposed channels that can be vertically aligned above a substrate with each channel being surrounded by a gate structure are formed. By forming ESD protection circuit structures in regions below the IGFETs, an older process technology may be used and device size may be decreased. Furthermore, planar IGFETs of FinFETs may be formed in other regions to decrease device size and improve costs.
