Abstract: Provided is a substrate processing apparatus. The substrate processing apparatus includes a chamber in which a process with respect to a substrate is performed, a susceptor which is installed in the chamber and on which the substrate is placed, a plurality of lift pins passing through the susceptor to support the substrate, and a plurality of protection plugs protruding from a bottom surface of the susceptor to surround a portion of each of the lift pins protruding from the bottom surface of the susceptor.

Abstract: A sliding interlocking reclining seat structure includes a seat cushion assembly configured to move forward and backward within a vehicle body, a rail assembly positioned on a lower end of the seat cushion assembly and configured so that the seat cushion assembly slides, a seatback assembly connected to the seat cushion assembly through a hinge part and configured to move in a height direction of the vehicle body in response to the sliding of the seat cushion assembly, and a latch assembly, disposed on an upper end of the seatback assembly, including a guide bracket having a slot formed therein in a height direction, and configured to be fastened to one end of a striker fixed to the vehicle body. While the seat cushion assembly slides, the latch assembly vertically moves along the slot when fastened to the striker, and the seatback assembly moves in the height direction of the vehicle body as the hinge part moves forward.
