Patent ID: 8662886

Claim:
A pressure stabilizing system for wafer fabrication processing, the system comprising: a wafer loading system for loading one or more unprocessed wafers into a horizontal diffusion furnace for processing having a loader for loading and unloading, wherein the wafer loading system includes a boat loader integrated with a paddle and sealing door, wherein the sealing door forms a sealing gap between the sealing door and a first area of the horizontal diffusion furnace, the horizontal diffusion furnace capable of operation for a predetermined recipe with the wafer loading system, a gas cabinet and a power system to process the one or more unprocessed wafers, a pressure stability control system having a pressure sensor in a first area of the furnace in communication with a loading controller capable of adjustably positioning a loader of the wafer loading system to a predetermined horizontal location in relation to a comparison of a measured pressure in the first area and a predetermined formation pressure range, wherein the first area is a scavenger area in the furnace, and an exhaust release system capable of releasing exhaust gas from the furnace.
