Abstract: A vapor chamber structure includes an aluminum upper plate, an aluminum lower plate, a working fluid and multiple micron-sized recesses. The aluminum upper plate has a first side and a second side. The aluminum lower plate has a third side and a fourth side. The aluminum upper and lower plates are correspondingly mated with each other to define an airtight chamber. The working fluid is filled in the airtight chamber.
