A Korean company has developed a mass production technique for Large Area Single Crystal Graphene of a scale of over 30 inches that has a uniform characteristic, for the first time in the world, and will start the mass production during the second half of the year. As a result, it seems the early commercialization of graphene products will be made possible.

The new material of dreams, graphene, has been developed in small sizes of less than one inch in laboratories, but no one had ever succeeded in mass producing in a large area of over 30 inches. The graphene that had been developed until now were all merely the size of a nail(100×100㎜).

On April 7th, Haesung DS announced that they had recently developed the core technology of mass producing high quality, 540×680㎜(34 inches) sized graphene.

The graphene that Haesung DS has developed is the world’s largest. The synthetic time, which was an obstacle in commercialization, was dramatically reduced to 17 minutes. Until now, the time needed in synthesizing a single sheet of graphene was three to seven hours.

This company developed a separate synthetic equipment for graphene with a semiconductor equipment company called PNS. This equipment can synthesize a total of four graphene sheets at once, through Chemical Vapor Deposition(CVD) that uses the rapid thermal annealing technique. The rapid thermal annealing technique that allows rapid heating and cooling during vacuum processing played a key role in reducing the processing time.
