Abstract

PURPOSE:To reduce the particles adhering to the surface of a semiconductor wafer by providing an adhesion preventive member, whose surface has many projections, at least in the vicinity of the part where plasma chemical reaction occurs and which is on the surface of the substrate inside an ECR plasma reaction chamber. CONSTITUTION:The adhesion preventive member 14, which surrounds the space where ECR plasma chemical reaction occurs above the semiconductor wafer 8 inside an ECR plasma reaction chamber 6, is provided on the inner surface, and has a number of, for example, integral hexagonal honeycombed-pattern projections 15. The particles tending to adhere to the place excluding the surface of the wafer 8 in the plasma processing mostly adhere to the inner surface of the adhesion preventive part 14. The particles hardly separate because of the projections. Since the adhesion preventive part 14 is replaceable, when the adhering reaction products 12 become thick, it can be replaced.

By the way, the conventional EC
The R plasma processing apparatus has a non-negligible problem that particles adhere to, for example, an insulating film formed on the surface of a semiconductor wafer. The details of this problem are as follows. That is, the conventional E as shown in FIG.
Since the raw material gas in the film formation in the CR plasma processing apparatus spreads over the entire chamber 6, not only the reaction products are deposited on the surface of the semiconductor wafer 8, but also the inner surface of the chamber inner wall 11 and other portions around the plasma extraction window 5 and the susceptor 9 are formed. Similarly, a film is formed by depositing on each exposed surface. Then, the film is peeled off at a proper time, and becomes a particle in question and adheres to the surface of the semiconductor wafer 8.

The peeling of the film formed on the inner surface of the chamber 6, which is considered to be the cause of the particles, is caused by the collision of ions and electrons present in the plasma at the time of film formation, which causes the temperature inside the chamber 6 to rise and It is considered that there is a difference in the thermal contraction rate between the deposited film caused by the temperature effect of 1) and the underlying metal of the inner wall 11 of the chamber 6 made of SUS308 or the like, and that it is due to the temperature change. Then, if particles adhere to the film formed on the surface of the semiconductor wafer 8, they cause problems such as dielectric breakdown and leaks, leading to a decrease in yield and a decrease in reliability. Especially in the recent development of ULSI,
With high integration, the demands for miniaturization processing technology and cleaning technology have become more and more severe, and about 200

Most of the particles that adhere adhere to the inner surface of the deposition-preventing portion 14. And
The particles adhered to the inner surface of the deposition-inhibitory portion 14 are in a sticky state unlike the case of adhering to a flat surface because the adhered inner surface has irregularities, and are difficult to peel off. Therefore, the number of particles adhering to the surface of the semiconductor wafer 8 taken out from the ECR plasma processing apparatus after finishing the processing can be considerably reduced as compared with the conventional case.

Even if the temperature drops sharply due to the stop of the CR plasma treatment, no sudden temperature change occurs on the surface of the deposition-preventing portion 14. Therefore,
Even if there is a difference in thermal expansion coefficient between the reaction product (for example, SiO 2 ) and the deposition-preventing portion 14, the reaction product hardly peels off, and the number of particles generated can be further reduced. In addition, without providing a heater inside the deposition-inhibitory portion 14,

According to this embodiment, as in the case of the embodiment shown in FIG. 1, it is unavoidable that the reaction product 12 adheres to a place other than the surface of the semiconductor wafer 8, but the semiconductor wafer 8 does not. Most of the particles that adhere to areas other than the surface adhere to the inner surface of the deposition-inhibitory portion 14.
The particles adhering to the inner surface of the deposition-inhibitory portion 14 have a sticky state unlike the case of adhering to a flat surface because the adhered inner surface has irregularities, and are difficult to peel off. Therefore, the number of particles adhered to the surface of the semiconductor wafer 8 taken out from the ECR plasma processing apparatus after the processing by the plasma processing can be considerably reduced as compared with the conventional case.

Moreover, since the internal area of the chamber 6 is small, the absolute amount of the reaction product attached to the portion of the chamber 6 other than the deposition-preventing portion 14 is small, and eventually to the surface of the semiconductor wafer 8. The absolute number of particles can be reduced. Further, by reducing the inner area of the chamber 6, there is an advantage that the exhaust speed can be improved and the vacuum can be increased.

Further, the heater may not be provided inside the deposition-inhibiting portion 14, and the deposition-inhibiting portion 14 may be heated by a heat source such as an external lamp. By the way, although the deposition-inhibitory portion 14 is formed separately from the inner wall of the chamber 6 and is replaceable, it may be formed integrally with the chamber 6. In this case, when the reaction product becomes thick, the inner surface of the chamber 6 may be washed.
