Abstract:
1. A processing apparatus, comprising: a loading chamber; a buffer chamber connected to the loading chamber; a first process chamber connected to the buffer chamber; an unloading chamber connected to the first process chamber, and an air pad disposed in each of the chambers, a heater in respective centers of each of the buffer chamber and the first process chamber for controlling a temperature of first and second substrates, wherein a processing path through the processing apparatus is a forward in-line path in a direction through the loading chamber, the buffer chamber, the first process chamber, and the unloading chamber, wherein each air pad has a plurality of holes for injecting a gas, wherein the first and second substrates are maintained in a balanced and substantially vertical state by a pressure by the gas generated by the air pad, wherein the first and second substrates are seated respectively on rollers to transfer the substrates through the processing path, wherein the first process chamber includes first and second targets mounted on first and second cathodes, and wherein the first substrate paralleling with the first cathode is disposed between the first cathode and the heater, the second substrate paralleling with the second cathode is disposed between the second cathode and the heater, and the first and second substrates are non-parallel with the heater.
