Apply plasma treatment method. Background art
- the plasma source used in the plasma processing apparatus there are a high-frequency capacitively coupled plasma source, a microwave ECR plasma »and a high-frequency wave induction combined plasma, etc. It is used for each processing process.
- a plasma processing image equipped with a high-frequency inductively coupled plasma source has rapidly spread in recent years.
- One example of the inductively coupled plasma processing apparatus is disclosed in Japanese Patent Application Laid-Open No. 2-235332.
- a loop, coil, or spiral high-frequency antenna which is constrained outside the processing chamber through an insulating material such as quartz, which forms a part of the champer, has a frequency of several hundred kHz.
- the antenna may dazzle in the chamber in the high-frequency inductively coupled plasma processing apparatus.
- a helical antenna that is a high-frequency 8-conducting coil is used. It is crimped to a position in the champ facing the semiconductor wafer to be processed.
- the induction current is generated in the plasma, and the plasma and the ⁇ frequency antenna are inductively coupled in an electric circuit manner (the antenna is a primary coil, and the current in the plasma is 2).
- the transformer circuit is regarded as the next coil.
- the wave antenna for A is placed on the atmosphere side through an insulating material such as quartz for the plasma in the processing chamber.
- an insulating material such as quartz for the plasma in the processing chamber.
- the insulation must have sufficient strength to withstand the atmospheric pressure, and the material to be treated must be large. Under the current situation where the area is increasing, it is necessary to increase the thickness of the insulating material according to the area of the workpiece.
- the antenna and the plasma are capacitively coupled in addition to the inductive coupling.
- the material is frequently cut by the plasma. Therefore, in order to increase reliability sufficiently, it is necessary to thicken the insulating material. * As thicker, as described in the fife statement of Ke 11er et al. In Jounal of Vacuum Science All (5), Sept / Oct 1993, p. The generation efficiency of the plasma is significantly reduced, which has a negative effect on the ignitability and stability of the plasma.
- the surface of the high-frequency antenna is protected by a material, but in the case of inductively coupled plasma lightning, strong plasma is generally generated in the immediate vicinity of the antenna. In the case of the ft using, the damage of the protective film is extremely large. Since the antenna itself is made of metal, if the protection R is broken, gold ions will be generated, and gold JR contamination will occur on the semiconductor wafer. In addition, the antenna itself needs to be replaced, resulting in a problem that maintenance requires a great deal of time and cost. In addition, a cooling plate is placed behind the antenna, and this plate needs to be insulated from the antenna. With such a structure, it is difficult to make the cooling plate thermally adhere to the antenna. Another drawback is that under low pressure such as in vacuum or plasma processing, heat transfer at the contact surface of the structure is extremely poor, so that the cooling effect of the cooling plate on the antenna cannot be expected much. There is.
- the object behind the antenna crotched on the opposite side of the object As high as the side, a high density plasma is generated.
- the plasma behind the antenna is not used effectively for the plasma treatment of the workpiece, which substantially reduces the plasma generation efficiency and exposes the backside chamber walls to strong plasma. Causes a problem.
- the present invention has been made to solve the above problems and disadvantages of the prior art. That is, the object of the present invention is to control the plasma generation efficiency in the plasma processing apparatus ⁇ in which the high-frequency antenna is imaged on the large side, and to control the plasma generation efficiency in the plasma & processing apparatus installed in the processing chamber.

It is another object of the present invention to provide a plasma processing apparatus that is highly reliable and easy to maintain.
- the upper SB section is solved by integrating the high-frequency antenna with the chamber inside the processing chamber.
- the antenna supplied with the power from the power source uses a suitable thickness of insulating material to cover the M with the jumper, and the surface in contact with the plasma to protect it from plasma or reactive gas for plasma processing.
- an insulating material such as alumina or quartz.
- the antenna comes into contact with the plasma through the range material.
- the plasma processing apparatus according to the prior art in which the induction coil is E-lighted to the atmospheric side, is used.
- the quartz window which is used as an insulating material, it can be made thinner because it does not need to be exposed to atmospheric pressure.
- the insulating material is too thick to support atmospheric pressure, do not create a gland M on the antenna and surrounding material M, or reduce the pressure in this space. It is desirable to always keep the pressure inside the processing chamber New Actually, the insulating material and the W of the antenna may have a small gap M or a contact surface due to their structure. However, as described in the section of the prior art, under low pressure, heat transfer in this portion is difficult. Bad things can cause the antenna to heat up.
- the plasma generation efficiency is improved, and stable plasma can be generated under a wider range of operating conditions. Further, even if the insulating material for protecting the antenna is cut down and reduced, only the material needs to be replaced, so that the maintainability is improved as compared with the antenna of the related art. As a result, the plasma processing performance and the operating rate of the device ⁇ are improved, and fine etching processing at high throughput, and commercial R processing and surface treatment can be performed.
