We have produced gold particles whose sizes range from several tenth nanometers up to about one micrometer. The small gold particles are distributed on a gold thin film of thickness $50\sim 80$\AA. The method for the formation is simple. We first evaporated the gold thin film, and then applied DC field along the film. When the field increases from zero to 30 V, and the measured current increases from 0 to 650 mA, the particles were formed. The sizes and the distribution distances could be controlled by the applied DC field.
