CONSTITUTION: A wafer, a doped material film such as a photoresist layer or a SOG(Spin On Glass) film, is loaded on a susceptor(S) in a reaction chamber(CB). Controlling a vacuum pump(P) and a valve(V), the pressure of inside chamber(CB) is maintained as low pressure. Reaction gas like N2 gas or Ar gas is injected into the chamber(CB) through a gas injection ring(GR). Using a high voltage power source(HVP), negative high voltage is applied on a cathode plate(CP), and negative low voltage is induced on a grid plate(GP) by a low voltage power source(LVP). The reaction gas in the chamber(CB) is ionized and produced holes and electrons. The holes move toward the grid plate(GP), and accelerate due to the electric field, formed by the negative high voltage. The holes are collided on the bottom of the cathode plate(CP), and secondary electrons are exited. The exited secondary electrons go faster to the loaded wafer on the susceptor(S) because of the electric field. The number of electrons and its energy are various by changing the grid voltage and the cathode voltage. The thickness of cured SOG film can be controlled by guiding the electron beam energy. Using the electron beam irradiating process, a double layered material film can be made.
