Abstract

PURPOSE:To form an SiO2 film with extremely high purity, in forming the SiO2 thin film by a plasma CVD apparatus utilizing high frequency glow discharge, by a method wherein a capacitor is provided to a lower electrode while the interior of a reaction chamber is formed from a quartz material. CONSTITUTION:The wall part 1 of a reaction chamber and the insulating plate 4 attached to an upper high frequency electrode 3 in a plasma CVD apparatus is constituted from quartz material while a substrate 7 is placed on a lower high frequency electrode 8. After the interior of the reaction chamber is evacuated, the substrate 7 is heated to about 500 deg.C by a heater 6 and SiH4 and N2O are introduced into the reaction chamber from an introducing port 9 as reactant gases. High frequency voltage is applied between the high frequency electrodes 5, 8 to generate high frequency plasma and an SiO2 thin film is formed on the substrate 7. The control of potential is facilitated by a capacitor 15 connected to the lower high frequency electrode 8 while the variation of the reaction state of the reactant gases or a plasma sheath width is enabled and the mixing of impurities is eliminated because the inner wall 1 of the reaction chamber and the insulating plate 4 are made of a quartz material to obtain the high purity SiO2 film.

The plasma CVD apparatus that is currently most in practical use is a bipolar parallel plate type capacitively coupled type. Although this method has a simple configuration, the high-frequency electrode is installed directly in the reaction chamber, and the reverse spatter effect caused by ions generated by the high-frequency glow discharge inevitably causes impurities to be mixed into the formed thin film from the electrode material. However, contamination of impurities from the walls of the reaction chamber also poses a problem. In particular, in the plasma CVD method, since active gas is introduced, stainless steel materials are often used for the constituent materials of the electrodes and reaction chambers, and metal elements constituting the stainless steel materials may contaminate the thin film. When applied as a thin film forming technology for semiconductors such as LSI, many problems occur. Furthermore, in conventional bipolar parallel plate type plasma CVD equipment, the only electrical control method that can be used to change the plasma density and actively change the reaction state of the active scum introduced into the reaction chamber is high-frequency power, which is manually applied. There is no. Changing the high-frequency power not only changes the plasma density, but also changes other plasma factors, changes in the width of the plasma generated between the high-frequency electrode and the plasma, and changes in the width of the plasma. Many parameters, including changes in the excitation voltage generated at the high-frequency electrode, change simultaneously, which greatly affects the reproducibility of forming conditions and the quality of the thin film.

In the present invention, the capacitor 1 connected to the lower high frequency electrode 8
5, the potential control on the high-frequency electrode 8 with respect to the plasma potential is 0T, and even at a high-frequency power of 1bj-, the reaction state of the reactant gas and the change in plasma north width are =f, and under various conditions. can now be set, and a thin film of noricon oxide with excellent electrical and stoichiometric compositions can be easily obtained. In addition, by using quartz material for the insulating plate 4 installed in front of the upper high-frequency electrode 5 and the reaction chamber wall 1 close to the end of the upper high-frequency electrode 5, it became possible to form a thin film of noricon oxide with extremely low contamination of impurities. . For example, when the substrate temperature is 3000C, the flow rate of the reaction gas introduced is 100%.
7 runs; 20SCCM, nitrous oxide; 200SCCM,
Introducing flow rate ratio: S i H4 / N20 = 10, high frequency power is 100 W, and when an oxidation/licon coating is formed on a paste-contact type substrate (resistivity: 4 to 5 Ω-(7), boro/doped), 15 capacity 300~350PF
When the range was set, a potential of several tens of square meters was generated on the lower high-frequency electrode 8 with respect to the plasma potential, and the reaction state of oxidation/licon formation was changed, resulting in an increase in the thin film formation rate. That is, in the conventional bipolar parallel plate type, the thin film formation rate was 200 to 250 A0/mln under the above conditions, but in the present invention, it was 380 to 500 A'/min, which is about 1.5 to 2 times the above mentioned rate. was gotten. Further, in evaluation of dielectric strength characteristics, it was found that according to the present invention, a dielectric strength of 5 to 9 M V/cm, which is about 2 to 3 times that of a case formed using a normal bipolar parallel plate, can be obtained. This is thought to be because the reaction state of the reaction gas can be increased, so that the stoichiometric composition of the oxidation/recon thin film can be sufficiently satisfied to 75-75%. Furthermore, it has been found that the above effect is further enhanced by the effect of confining the high frequency plasma between the upper high frequency electrode 5 and the lower high frequency electrode 8 by using an insulating material such as quartz or alumina for the reaction chamber wall 1. . Regarding impurities, S
I MS (5secondary Ion Ma)
According to the results of analysis using the ssSpectroscopy method, iron, nickel, chromium, etc., which are the constituent elements of stainless steel, were detected with the normal bipolar parallel plate type, but with the present invention, they are almost impossible to detect, and the semiconductor It has been revealed that this method has extremely good characteristics as a thin film forming apparatus for use in commercial applications.
