Movable Deposition Source Access for Vacuum Chamber Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The maintenance of large deposition apparatuses is challenging due to their size and weight, requiring workers to enter the apparatus directly for resupplying raw materials and replacing components, which is difficult and inefficient.
Innovation Solution
A deposition apparatus with a door that opens and closes an opening in the process chamber, allowing access to the deposition source from outside, and a source moving part to facilitate the movement of the deposition source parallel to the substrate, enabling maintenance without entering the chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the deposition apparatus is made larger to accommodate larger substrates, then the processing capacity is improved, but the maintenance difficulty increases
Solution Approach 1:
The door is divided into a first door portion and a second door portion that can move relative to each other. The second door portion can be independently opened to provide access to the deposition source, while the first door portion remains closed to maintain the vacuum environment. This segmentation allows maintenance operations without requiring full chamber access.
Solution Approach 2:
The deposition source is designed to be movable and can be extracted from the process chamber through the opening in the door. The source moving part enables the deposition source to be partially or fully removed from the chamber, allowing maintenance personnel to service it from outside the vacuum environment.
2Ease of operation
If workers enter the deposition apparatus for maintenance, then direct access to components is improved, but safety risks and maintenance time increase
Solution Approach 1:
A source moving part acts as an intermediary mechanism between the deposition source and the maintenance personnel. This mechanism enables the deposition source to be moved to a maintenance position where it can be serviced without personnel entering the vacuum chamber, eliminating the need for protective gear and reducing maintenance time.
3Ease of repair
If the door is made larger to improve access, then maintenance ease is improved, but vacuum sealing difficulty increases
Solution Approach 1:
The door structure is segmented into multiple portions with independent opening capabilities. The first door portion maintains the vacuum seal while the second door portion provides controlled access. This segmentation allows maintenance access through a smaller opening while preserving the overall vacuum integrity of the chamber.

AI summary
A deposition apparatus includes a process chamber that provides a space to process a substrate, and including a side surface in which an opening is defined, a door configured to open or close the opening of the process chamber, and a deposition source configured to supply a deposition material to the substrate in the process chamber, and including an upper surface of which at least a portion is exposed through the opening when the opening is opened by the door.
