Latest Patents

Fukidome's latest patents include a stacked body that incorporates a graphene film and an electronic device utilizing this film. The first patent describes a stacked body that consists of a silicon carbide substrate with a first main surface forming an angle of 20° or less with a silicon plane. A graphene film is disposed on this surface, featuring an atomic arrangement that is oriented in relation to the silicon carbide substrate. The exposed surface of the graphene film has an area ratio of a region with a full width at half maximum of G' of 40 cm or less under Raman spectroscopy analysis, which is 50% or more. This design enables high mobility to be stably ensured in electronic devices that include the graphene film.

The second patent also focuses on a stacked body and electronic device. It describes a substrate made of silicon carbide with a first main surface forming an angle of 20° or less with a carbon plane. The graphene film is again disposed on this surface, with specific characteristics regarding the exposed surface. In this case, there are 10 or fewer regions present per 1 mm, each region containing 10 or more graphene layers and having a circumcircle diameter between 5 µm and 100 µm. This innovation similarly ensures high mobility in electronic devices that incorporate the graphene film.
