Graphene, a component found in 2004, is (for some) the material of the future: indeed, this two-dimensional crystal from carbon is stronger than steel (about 200 times) and 6 times lighter. More interesting, it could replace silicon transistors due to its thermal capacity (it does not heat) and conductivity (electrons move faster in graphene than in silicon).
Fujitsu innovates
Fujitsu innovating, improving one of the creative techniques of graphene. Currently, one of the techniques - CVD, Chemical Vapor Deposition for - is to be heated between 800 and 1 100 ° a metal catalyst that will allow transfer of graphene on a substrate. Besides the fact that we should use high temperatures, this method is unusable for wafers of 300 mm (the current standard). The new Fujitsu technology reduces the temperature (it is still fairly high, with 650 °) and especially to work directly on large wafers. Currently, Fujitsu is able to transfer a wafer of 75 mm but the company indicates that the development on 300mm wafers poses no problems.
In practice, it is not ready to see graphene transistors in our computers, but the changes (in an area still very young) are promising.
