POD Cleaning Chamber Segmentation for Contamination-Free Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for cleaning and drying PODs in the semiconductor industry do not efficiently separate cleaning and drying processes, leading to contamination and reduced productivity.
Innovation Solution
A POD cleaning apparatus with separate cleaning sub-chambers and drying chambers, where the cleaning sub-chamber and drying chamber are spatially separated to prevent contamination and enhance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cleaning and drying are performed in the same chamber, then device complexity is reduced, but contamination risk increases and cleaning efficiency decreases
Solution Approach 1:
The cleaning chamber is divided into two separate spaces: a cleaning sub-chamber for cleaning operations and a drying chamber for drying operations. This segmentation prevents contamination by isolating the cleaning process from the drying process, while still achieving the invention's goal of improved reliability through contamination prevention.
2Reliability
If inner POD and outer POD are cleaned separately in different chambers, then contamination risk is reduced, but processing time and device complexity increase
Solution Approach 1:
Both the inner POD and outer POD are accommodated in the same cleaning chamber simultaneously. The chamber can hold multiple PODs at once, allowing parallel cleaning operations. This merging approach reduces processing time compared to sequential cleaning, while the separate drying chamber ensures contamination prevention through spatial isolation of cleaning and drying functions.
3Device complexity
If chemical flow paths are not separated, then device complexity is reduced, but foreign material contamination increases
Solution Approach 1:
The cleaning chamber is segmented into distinct zones with separate chemical flow paths. Cleaning chemicals and drying gases flow through separate routes within the chamber, preventing foreign material contamination while maintaining relatively simple device structure through internal zoning rather than separate chambers for each function.

AI summary
Proposed is A POD cleaning apparatus including: a separate unit separating a POD introduced through an introducing inlet; a first transportation unit transporting a separation POD resulting from the separation in the separation unit; a plurality of cleaning chambers in each of which the separation POD transported by the first transportation unit is cleaned and dried; a chamber in which the separation POD dried in the cleaning chamber is vacuum-processed; a second transportation transporting the separation dried in the cleaning chamber to the vacuum chamber; and an assembly unit assembling the vacuum-processed separation PODs, in which each of the plurality of cleaning chambers includes: a cleaning sub-chamber where the separation POD transported by the first transportation unit is accommodated and cleaned; and a drying chamber where the separation POD transported from the cleaning sub-chamber is dried, and in which the cleaning sub-chamber and the drying chamber are spatially separated.
