Abstract: Disclosed is an integrated vacuum producing apparatus, which vacuumizes a process chamber of an apparatus for manufacturing semiconductors, flat panel displays, etc. or exhausts gaseous material and by-products generated within the process chamber to an outside so as to purify it. Gaseous material, e.g. gas, generated within a chamber for manufacturing a semiconductor, a flat panel display, etc. is exhausted through each separate exhaust line so as to be purified. Therefore, excessive operation of a purifying system can be prevented through distribution of exhaust gas so that life span can be extended according to the operation of the apparatus. Also, exhausting can be smoothly achieved through each exhaust line so that it is possible to prevent delay of a semi-conductor manufacturing process due to inability of exhausting, and to easily remove non-reacted gas and by-products in an exhausting process.

Abstract: A complex dry vacuum pump including a root rotor and a screw rotor is disclosed for manufacturing semiconductors and/or displays in a vacuum state in a process chamber, and discharging gaseous material and/or by-products generated during manufacturing to the exterior of the process chamber. The pump can provide high gas compression transfer efficiency so as to form a vacuum in the process chamber and/or keep high gas compression transfer efficiency when the gaseous material and/or by-products are discharged. Balance between the root rotor and the screw rotor can prevent vibration and noise generated in the vacuum pump, and molding material associated with the pump may allow a stator coil to be separated and prevent various by-products from flowing from the vacuum pump.
