    摘要: Sensors (70,72) detect a stock removal of a wafer (50) during polishing, and a CPU (74) calculates the stock removal in accordance with information from the sensors(70,72). The CPU (74) compares the actual stock removal detected by the sensors (70,72) and a model stock removal stored in RAM (84), and determines timings for dressing and replacing said polishing pad (16) in accordance with a difference between the actual stock removal and the model stock removal. The determination results are shown on a display (82).

    摘要: The first air guide groove (92) is formed at the bottom of a carrier (24) along the inner circumference of a circle whose radius corresponds to the maximum radius of a wafer (50). The air is supplied to the outer periphery of the wafer (50) through the first air guide groove (92) to form a pressure air layer (51) between the carrier (24) and the wafer(50). The formation of the pressure air layer (51) makes the air pressure applied to the wafer (50) uniform on the entire surface of the wafer (50), and thus, the wafer (50) can be polished under a uniform pressure force. The second air guide groove (94) is formed along the inner circumference of a circle whose radius corresponds to the minimum radius of the wafer (50), and therefore, the wafer (50) with an orientation flat or notch can be polished under a uniform pressure force.

    摘要: The polishing apparatus (100) comprises a turn table (10), which polishes a semiconductor wafer (2), and a holding and pressing part (20), which holds and presses the semiconductor wafer (2) against a polishing surface (12a) of the turn table (10). The holding and pressing part (20) transmits a force from an air bag (62) to the semiconductor wafer (2) via a pressurized fluid layer (L) to thereby press the semiconductor wafer (2) against the polishing surface (12a) via the pressurized fluid layer (L), so that the semiconductor wafer (2) can be polished. Thereby, it is possible to uniformly polish the semiconductor wafer (2).

    摘要: A wafer (50) is polished while it is pressed against a polishing cloth (16) through a pressure air layer, and a polished surface adjustment ring (28) as well as the wafer (50) are pressed against the polishing cloth (16). The wafer (50) is polished in the state wherein a collapsing position of the polished surface adjustment ring (28) with respect to the polishing cloth (16) is set in such a way that the polishing pressure which is applied from the polishing cloth (16) to the wafer (50) can be constant.
