Abstract:
A wafer-processing apparatus includes: multiple discrete units of reactors disposed on the same plane; a wafer-handling chamber having a polygonal shape having multiple sides corresponding to and being attached to the multiple discrete units, respectively, and one additional side for a load lock chamber; a load lock chamber attached to the one additional side of the wafer-handling chamber; multiple discrete gas boxes for controlling gases corresponding to and being connected to the multiple discrete units, respectively; and multiple discrete electric boxes for controlling electric systems corresponding to and being detachably connected to the multiple discrete units, respectively, wherein the gas boxes and the electric boxes are arranged alternately as viewed from above under the multiple discrete units, and the electric boxes can be pulled out outwardly without being disconnected from the corresponding units so that sides of the gas boxes are accessible.
Abstract:
A film forming apparatus includes a susceptor, and a shower head provided above the susceptor and having a first passage and a second passage independent of the first passage formed therein, wherein the first passage is formed through the shower head by being provided with a first cavity surrounded by a first upper wall and a first lower wall, a first thin hole formed in the first upper wall, and a plurality of second thin holes formed in the first lower wall, the height of the first upper wall in the vertical direction is reduced with increase in distance from the first thin hole, and the second passage is formed in the same manner as the first passage.
