GFET-S30 (Die size 10 mm x 10 mm) - Processed in ISO 7 Cleanroom

 

The GFET-S30/5nm chip from Graphenea provides 30 backgated graphene devices distributed in a grid pattern on the chip. All the 30 devices have a 3-probe geometry, leveraging Graphenea’s proprietary High-K Metal Gate (HKMG) process flow to provide a backgate with an EOT = 5nm. This scheme allows for individual control of the conductance of each of the graphene channels within the die. There are 3 graphene channel dimensions to allow investigation of size dependence on device properties, enabling immediate optimization.
