A mercury-vapor lamp is provided with a reservoir in which a superfluous amount of mercury is stored in the form of liquid state. The liquid mercury in the reservoir is cooled to a certain temperature. The pressure of mercury-vapor is automatically reduced to the saturated pressure of the liquid mercury cooled. In this configuration, the pressure of mercury-vapor is controlled by adjusting the temperature of the liquid mercury stored in the reservoir.

Ultraviolet light is emitted mainly with 185 nm in wave length so that a thick silicon layer is fabricated by decomposition of silane gas at a high deposition speed. As a light source, a bulb is filled with an amount of mercury gas without dosing argon gas which enhances preferentially light with 254 nm in wave length.

An improved CVD apparatus for depositing a uniform film is shown. The apparatus comprises a reaction chamber, a substrate holder and a plurality of light source for photo CVD or a pair of electrode for plasma CVD. The substrate holder is a cylindrical cart which is encircled by the light sources, and which is rotated around its axis by a driving device. With this configuration, the substrates mounted on the cart and the surroundings can be energized by light or plasma evenly throughout the surfaces to be coated.

摘要:
Plasma CVD method and apparatus are described. The apparatus comprises a vacuum chamber in which two pairs of electrodes are provided. A high frequency voltage is applied to one of the pairs in order to produce a plasma from a reactive gas in the chamber. A substrate to be coated is located between the other of the pairs. A relatively low frequency voltage is applied to the other pair of electrodes. By virtue of the low frequency voltage, the substrate is exposed to the bombardment of ions of the plasma during deposition. The bombardment functions to remove relatively soft portions of the depositing material.
