Existing techniques fail to effectively detect the complete separation of a solvent or dispersion medium from a solid raw material in solutions or dispersion systems, which is crucial for precise raw material supply in semiconductor manufacturing.
Innovation Solution
A raw material supply apparatus comprising a container for storing a solution or slurry, a removal part to evacuate the solvent or dispersion medium, a detection part to confirm the completion of removal, and a heater to sublimate the resulting solid material, enabling the detection of solvent or dispersion medium separation through analysis of components in the fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a solution or dispersion system is used to supply solid raw material, then the raw material can be supplied in a dissolved or dispersed state, but it becomes difficult to detect when the solvent or dispersion medium has been completely removed from the solid raw material
Solution Approach 1:
The patent introduces a detection part that acts as an intermediary to detect the completion of solvent removal. The detection part includes a sensor that detects the presence or absence of solvent vapor in the atmosphere inside the container, providing indirect but reliable information about the solvent removal status without directly contacting the solid raw material
Solution Approach 2:
The patent replaces direct mechanical or visual inspection methods with a sensor-based detection system. The sensor detects solvent vapor concentration in the atmosphere, substituting complex mechanical monitoring with a simpler, more reliable electrical sensing mechanism that can accurately determine when solvent removal is complete
2Manufacturing precision
If the solvent or dispersion medium is removed to separate it from the solid raw material, then the solid raw material can be obtained in a pure state, but the process time becomes extended
Solution Approach 1:
The patent implements a feedback mechanism where the detection part continuously monitors the solvent vapor concentration and provides real-time information to the control system. When the sensor detects that solvent vapor concentration falls below a threshold (indicating complete removal), the system automatically stops the solvent removal process, preventing unnecessary extended operation time while ensuring complete separation
Solution Approach 2:
The system performs preliminary detection of solvent vapor presence before initiating or continuing the solvent removal process. By detecting the initial state and monitoring changes in real-time, the system can optimize the removal duration and stop exactly when completion is achieved, avoiding both insufficient removal and unnecessary extended processing
3Productivity
If continuous operation is maintained in the raw material supply apparatus, then productivity is improved, but the apparatus complexity increases due to multiple components
Solution Approach 1:
The detection part serves multiple functions: it detects solvent vapor concentration, determines completion of solvent removal, and provides feedback for controlling the solvent removal process. This multi-functionality allows continuous operation capability without adding excessive complexity, as a single integrated detection system performs multiple critical tasks
Solution Approach 2:
The patent combines the detection function with the control system, merging the detection part and control unit into an integrated system. The sensor detects solvent vapor and the control unit processes this information to automatically manage the solvent removal process, combining multiple functions into a unified apparatus that enables continuous operation without proportionally increasing complexity
