Abstract: A method for forming silicon dots, wherein a hydrogen gas (or and also a silane type gas) is introduced to a vacuum chamber (1), a plasma exhibiting a ratio of the luminous intensity of a silicon atom at a wave length of 288 nm to the luminous intensity of a hydrogen atom at a wave length of 484 nm of 10.0 or less is generated in the chamber, and silicon dots having a particle diameter of 20 nm or less are formed by the chemical sputtering under said plasma on a substrate.
