IBM is developing 10,000 times faster graphene chip

IBM builds graphene chip that’s 10,000 times faster, using standard CMOS processes. Engineers at IBM Research have built the world’s most advanced graphene-based chip, with performance that’s 10,000 times better than previous graphene ICs. The key to the breakthrough is a new manufacturing technique that allows the graphene to be deposited on the chip without it being damaged (something that has heretofore been very hard to achieve).

Perhaps more importantly, though, this new method is actually compatible with standard silicon CMOS processes. In short, we are closer than ever before to realizing a commercial graphene computer chip.


What IBM Research has built is a silicon chip, on a standard 200mm silicon wafer, using a standard CMOS fabrication process. This chip, which is a radio frequency (RF) receiver, is just a normal chip, with resistors, capacitors, and transistors — except for one bit: the transistor channels are made of graphene. The chip’s function is very rudimentary: It receives and restores wireless signals in the 4.3GHz range.
