A substrate carrying device capable of causing a substrate to float by a gas can be manufactured at a low manufacturing cost and can suppress the consumption of a gas for carrying the substrate. The substrate carrying device includes a carrying passage forming member forming a carrying passage along which a substrate is carried, exhaust grooves extending parallel to the carrying passage in the upper surface of the carrying passage forming member, a plurality of pairs each of right and left carrying gas flow grooves formed in the upper surface of the carrying passage forming member, inclined to a substrate carrying direction so as to approach the exhaust grooves from the right-hand side and the left-hand side of the exhaust grooves, respectively, and having inner ends joined to the exhaust grooves, respectively, and gas spouting pores formed near outer ends of the carrying gas flow grooves to spout a gas for causing the substrate to float and for creating substrate carrying gas flows flowing from the outer ends of the carrying gas flow grooves toward the inner ends of the carrying gas flow grooves. The gas spouted through the gas spouting pores causes the substrate to float and creates gas flows in the carrying gas flow grooves to propel the substrate in a carrying direction. The carrying passage is divided with respect to the carrying direction into passage sections, and the spouting of the gas through groups of the gas spouting pores assigned respectively to the passage sections is controlled to suppress the consumption of the gas.

In order to alleviate the affect of particles generated during operation of an elevation mechanism of a substrate conveyer means on the substrate that is transported in a substrate processing apparatus, a partition wall having a slit-like hole is provided in a casing that forms the outer housing of the elevation mechanism, whereby the casing is divided into a first chamber and a second chamber. A conveyer main unit holding a wafer is fixed to a rod-like support member. The support member has its end supported by a guide shaft. The guide shaft and a driving mechanism to move the support member upwards and downwards are provided in the first chamber. The support member descends and ascends along the guide shaft. A fan is disposed in the second chamber. A discharge outlet is formed at the bottom plane of the second chamber. By driving the fan, the atmosphere in the first chamber is attracted via the hole of the partition wall, whereby particles generated during the elevation of the conveyer main unit are discharged from the discharge outlet via the second chamber.

A carrier apparatus is provided with a first carrier mechanism, a second carrier mechanism, and a sensor. The first carrier mechanism has a holding portion holding a substrate, a driving pulley, an idler pulley, and a first endless belt, the first endless belt being provided between the driving pulley and the idler pulley and the holding portion being attached to the first endless belt. The second carrier mechanism has a driving source with a rotation output shaft, a speed reducing pulley fixed on the driving pulley and more than one second endless belts, the above more than one second endless belts being provided between the rotation output shaft and the speed reducing pulley. A sensor detects the state of the second endless belt, for example, the occurrence of cutting. As a result, even if the state of a carrier belt deteriorates, the holding portion is prevented from falling.

An apparatus for coating and developing a resist on a wafer comprises a carrier station provided with a plurality of carriers for receiving wafers and transfer tables, a processing section having a plurality of processing units, and a transfer robot provided between the carrier station and the processing section. The robot comprises a plate-shaped arm for transferring wafers between the carriers and the transfer tables, and two horseshoe-shaped forks for transferring wafers between the processing units and transfer tables. The robot is movable along a transfer path so as to make the arm and forks face the carriers, processing units and transfer tables.
