Abstract
According to one embodiment of the present invention, a substrate-processing apparatus includes: first and second chambers parallel to each other; a plurality of first lift pins disposed in the first chamber, and supporting a first substrate transferred to the first chamber; a plurality of second lift pins disposed in the second chamber, and supporting a second substrate transferred into the second chamber; and a transfer robot transferring the first and second substrates into the first and second chambers. The transfer robot includes first and second blades that simultaneously elevate to transfer the first and second substrates to the upper sides of the first and second lift pins, respectively. The first and second blades can move to: a moving position higher than the upper ends of the first and second lift pins; a first loading position in which the first blade is lower than the upper ends of the first lift pins and the second blade is higher than the upper ends of the second lift pins; and a second loading position in which the first and second blades are lower than the upper ends of the first and second lift pins.
