摘要:
Disclosed is a reactor for treating flat substrates, comprising a vacuum chamber (11) and a process chamber (9). A first electrode (5) and a counter electrode (7) which form two opposite walls of the process chamber are provided for generating a plasma. The counter electrode can accommodate the substrate (3). The reactor further comprises means for introducing (19, 23, 25) and evacuating gaseous material into and/or from process chamber, an inlet and outlet for the vacuum chamber, and a mechanism (41, 43) for varying the relative distance between the electrodes, a first relatively great distance being used when the process chamber is loaded and discharged and a second relatively short distance being used when the treatment is performed, and/or a device which is associated with the counter electrode, is used for accommodating substrates, and is designed such that the substrate is disposed at an angle alpha ranging from 0° to 90°, preferably at an angle of 1°, 3°, 5°, 7°, 9°, 11°, 13°, 15°, 17°, 20°, 25°, 30°, 40°, 45°, relative to the vertical direction at least while the treatment is performed, the substrate surface that is to be treated facing downward.
摘要:
To move an article (134) in and out of plasma (120) during plasma processing, the article (134) is rotated by a first drive (140) around a first axis (140X), and the first drive is itself rotated by a second drive (150). As a result, the article (134) enters the plasma (120) at different angles for different positions of the first axis (140X). The plasma cross section (114-0) at the level at which the plasma (120) contacts the article (134) is asymmetric so that those points on the article (134) that move at a greater linear velocity (due to being farther away from the first axis (140X) move longer distances through the plasma (120). As a result, the plasma processing time becomes more uniform for different points on the article surface. In some embodiments, two shuttles (710-1, 710-2) are provided for loading and unloading the plasma processing system. One of the shuttles (710-1) stands empty waiting to load them into the system, while the other shuttle (710-2) holds unprocessed articles (134) waiting to load them into the system. After the plasma processing terminates, the empty shuttle unloads processed articles (134) from the system, takes articles (134) away, and gets unloaded and reloaded with unprocessed articles (134). Meanwhile the other shuttle loads unprocessed articles (134) into the system and the plasma process begins. Since the plasma processing system does not wait for the first shuttle (710-1), the productivity of the system is increased.
摘要:
A magnetic field enhanced single wafer plasma etch reactor (60) is disclosed. The features of the reactor include an electrically-controlled stepped magnetic field for providing high rate uniform etching at high pressures; temperature controlled reactor surfaces including heated anode surfaces (walls and gas manifold) and a cooled wafer supporting pedestal/cathode (70,72); and a unitary wafer exchange mechanism (74) comprising wafer lift pins (79) which extend through the pedestal and a wafer clamp ring (78). The lift pins and clamp ring are moved vertically by a one-axis lift mechanism (140) to accept the wafer from a co-operating external robot blade (76), clamp the wafer to the pedestal and return the wafer to the blade. The electrode cooling combines water cooling for the body of the electrode (70) and a thermal conductivity-enhancing gas interface between the wafer and electrode for keeping the wafer surface cooled despite the high power densities applied to the electrode. A gas feed-through device (114, 175, 176) applies the cooling gas to the RF powered electrode (72) without breakdown of the gas. Protective coatings/layers (81,83) of materials such as quartz are provided for surfaces such as the clamp ring and gas manifold. The combination of these features provides a wide pressure regime, high etch rate, high throughput single wafer etcher wich provides uniformity, directionality and selectivity at high gas pressure, operates cleanly and incorporates in-situ self-cleaning capability.

A magnetic field enhanced vacuum single wafer plasma etch reactor (60) is disclosed. The features of the reactor include an electrically-controlled stepped magnetic field for providing high rate uniform etching at high pressures; temperature controlled reactor surfaces including heated anode surfaces (66 I, 67 I) (walls and gas manifold) and a cooled wafer supporting cathode (72) and a unitary wafer exchange mechanism comprising wafer lift pins (79) which extend through the pedestal (72) and a wafer clamp ring (78). The lift pins (79) and clamp ring (78) are moved vertically by a one-axis lift mechanism (140) to accept the wafer (75) from a cooperating external robot blade (76), clamp the wafer (75) to the pedestal (72) and return the wafer (75) to the blade (76). The electrode cooling combines water cooling (170, 172, 174) for the body (128) of the electrode and a thermal conductivity-enhancing gas parallel-bowed interface between the wafer (75) and electrode (72) for keeping the wafer surface cooled despite the high power densities applied to the electrode. A gas feed-through device (175, 176, 178, 180) applies the cooling gas to the RF powered electrode (72) without breakdown of the gas. Protective coatings/layers (811, 83) of materials such as quartz are provided for surfaces such as the clamp ring (78) and gas manifold (80). The combination of these features provides a wide pressure regime, high etch rate, high throughput single wafer etcher (60) which provides uniformity, directionality and selectivity at high gas pressures, operates cleanly and incorporates in-situ self-cleaning capability.

摘要:
A vacuum processing chamber (31) in a plasma processing unit (3A, 3B) is connected to a transfer chamber (2) and a wafer (W) is transferred from the transfer chamber (2) with the wafer aligned with a mount (4) in the vacuum processing chamber (31). The size and length of a waveguide (5) are the same for each plasma processing unit (3A, 3B) and a positional relation of the waveguide (5) with respect to transfer directions (M1, M2) of a transfer arm (61) is the same for each plasma processing unit (3A, 3B). Therefore, a positional relation of the waveguide (5) with respect to the wafer (W) placed on the mount (4) in a preset direction is the same for each plasma processing unit (3A, 3B).
