Abstract

PURPOSE:To prevent the clogging of gas introducing inlets and to improve the maintainability by arranging plural holes for spouting gas from the gas introducing inlets between a target and a target shield. CONSTITUTION:A target shield 9 is placed between a chamber 1 and a target 5, and plural holes for spouting gas from gas introducing inlets 6 are arranged between the target 5 and the target shield 9 so that gas is introduced from the vicinity of the target 5 in a uniform or prescribed distribution. Sputtered particles reach hardly the gas introducing inlets 6 because the target shield 9 acts as a barrier, so the particles do not deposit on the inlets 6.

Sputtering technology is a technology for forming a necessary thin film on a substrate by utilizing a phenomenon in which ionized gas collides with an electrode and knocks out atoms due to discharge in a low pressure of about 10 to IPa. Among these, magnetron structure sputtering, which uses so-called magnetron discharge where the electric field and magnetic field are orthogonal, to obtain high-density plasma near the target, is also called low-temperature high-speed sputtering, and is more effective than conventional bipolar sputtering. It is widely used because it has many advantages. (For example, [0NIC8 first issue PP43 to PP48]) Conventional sputtering electrodes with a magnetron structure include electrodes of the Brenna magnetron type, the S-gun type, and the coaxial type magnetron type. (For example, IEICE Technical Report Vot, 76, NO, 1090
PM71090P [Problem to be Solved by the Invention] When sputtering a target material while introducing a gas to obtain a predetermined thin film on a substrate using a sputtering electrode with a conventional magnetron structure, the gas introduction generally occurs while the target material is being sputtered. Sputtering is carried out uniformly or with a predetermined distribution on the surface where the target material is sputtered from the gas introduction part provided near the sputtering surface, but since particles of the sputtered target material also reach the gas introduction part. For example, the gas introduction part is a cylindrical pipe-like object with an outer diameter of about IQ mm and has multiple holes with a diameter of about 1 mm through which gas spouts out. In this case, the sputtered particles accumulate and eventually block some or all of the person from whom the gas is ejected, making it impossible to introduce gas with a specified distribution, or when one person is completely blocked. Such.
