PURPOSE: A method for manufacturing a quantum hole is provided to control the size, depth and interval of the quantum hole, by controlling a scan area, focusing of a beam, a scan interval of time and an accelerating voltage so that quantum holes having a uniform state are repeatedly mass-produced. CONSTITUTION: A voltage is applied to ultrafine particles(29) of a uniform size and a uniform electrical characteristic to accelerate the ultrafine particles, and the ultrafine particles are integrated through a condense lens. The ultrafine particles integrated and accelerated on a substrate(30) are scanned by a scanning method so that countless ultrafine particles of a uniform state are regularly formed on the substrate.
