We have a surprise today, with a patent from Advanced Micro Devices (AMD), the computer processor manufacturer. There has been no mention of AMD using graphene in the past, which makes today’s addition even more interesting.
The patent aims to protect the use of graphene in 3-dimensional electronics. US patent number 8304760 is a fairly quick read, as it simply describes the general use of graphene on sidewalls of a nanostructured electronic device. The goal is to provide a method of patterning graphene into sub-10nm ribbons, by growing it on the side of a thin substrate. There is no mention of the exact process for growing graphene on the nanostructure, or what the function of the graphene ribbons might be, which makes the whole patent a bit vague and generic. It must be that AMD is in the early stage of experimenting with graphene, but it is good to see such a big player entering the field. Let’s hope they team up with one of the graphene companies listed on this website to make our computer games even more realistic and our MATLAB computations less slow.
