Patent ID: 7624772

Claim:
A load lock apparatus including a carry port provided on a side of a carry-in/out section for carrying a substrate in/out from/to the outside, and a carry port provided on a side of a processing section for processing the substrate, said apparatus comprising: a first temperature controlling plate for controlling a temperature of the substrate carried in said load lock apparatus; and a second temperature controlling plate, wherein said first temperature controlling plate is placed on a front surface side of the substrate and said second temperature controlling plate is placed on a rear surface side of the substrate, wherein each of said first temperature controlling plate and said second temperature controlling plate comprises a plate body made of a porous carbon and a temperature controlling gas supply path for supplying a temperature controlling gas controlled in temperature to said plate body, wherein a surface of said plate body is provided with a permeable protection film, wherein the temperature controlling gas passes through said plate body, blows out from the surface of said plate body, and is supplied to the substrate, wherein an upper surface and an outer side surface of said plate body of said first temperature controlling plate are covered with a non-permeable protection material, and wherein said non-permeable protection material extending to a point below a lower surface of said plate body and said permeable protection film.
