In-line type film forming apparatus and method for manufacturing magnetic recording medium

摘要

There is provided an in-line type film-forming apparatus that can prevent a substrate from being dropped out of a carrier and convey the carrier at high speed. A first supporting member (41) is supported to be displaceable in a direction along an attaching face (S1) of the support base (40) in accordance with the growth of the first supporting member (41) due to thermal expansion in a horizontal direction, a second supporting member (42) is supported to be displaceable in a direction negating the growth of the first supporting member (41) due to thermal expansion in the horizontal direction along an attaching face (S2) of the first supporting member (42) in accordance with the growth of the second supporting member (42) due to thermal expansion in the horizontal direction, and a holder (3) is supported to be displaceable in a direction negating the growth of the first and second supporting members (41) and (42) due to thermal expansion in the vertical direction along an attaching face (S3) of the third supporting member (43) in accordance with the growth of the holder (3) due to thermal expansion in the vertical direction.

主权项

1. An in-line type film-forming apparatus comprising:
a plurality of chambers that perform a film-forming process; a carrier in which a holder holding a substrate as a film-forming target inside the plurality of chambers is installed; and a conveying device that sequentially conveys the carrier between the plurality of chambers, wherein the carrier comprises a support base, a first supporting member that is installed to the support base, a second supporting member that is installed to the first supporting member, and a third supporting member that is installed to the second supporting member and has a structure in which the holder is installed to the third supporting member, wherein the first supporting member is supported to be displaceable in a direction along an attaching face of the support base in accordance with growth of the first supporting member due to thermal expansion in a horizontal direction, wherein the second supporting member is supported to be displaceable in a direction along an attaching face of the first supporting member in accordance with growth of the second supporting member due to thermal expansion in the horizontal direction, wherein the holder is supported to be displaceable in a direction along an attaching face of the third supporting member in accordance with growth of the holder due to thermal expansion in a vertical direction, and wherein, out of the first supporting member, the second supporting member, the third supporting member, and the holder, any one member is supported to be displaceable in a direction negating growth of the other members in the horizontal direction and/or the vertical direction.
