Dual-Chamber Sample Analysis Apparatus for Wafer and Small Samples
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample analysis apparatuses face difficulties in simultaneously analyzing standard samples with different shapes, such as silicon wafers and non-wafer samples, due to structural limitations of having only one chamber, which restricts the ability to perform quantitative analysis effectively.
Innovation Solution
A sample analysis apparatus with two chambers: one for heating small samples to generate a first reactive gas and another for heating wafer samples to generate a second reactive gas, each with its own support and heating device, allowing for the analysis of various sample types through a transfer module and pipes that direct the reactive gases to an analysis device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only one chamber is used in the sample analysis apparatus, then the device complexity is reduced, but the ability to simultaneously analyze different sample types (silicon wafers and non-wafer samples) deteriorates
Solution Approach 1:
The sample analysis apparatus is divided into multiple independent chambers (first chamber for small samples, second chamber for wafer samples), allowing each chamber to be optimized for specific sample types while maintaining overall system functionality
Solution Approach 2:
Each chamber is designed with universal components (heating devices, supports, gas generation capabilities) that can handle different sample formats, enabling the system to analyze both small non-wafer samples and large wafer samples through the same analytical pipeline
2Device complexity
If a single chamber is used for all sample types, then the apparatus structure is simplified, but the measurement precision and consistency across different sample types deteriorates
Solution Approach 1:
Each chamber is equipped with locally optimized components (specific heating devices, supports, and gas generation systems) tailored to the requirements of particular sample types, ensuring consistent measurement precision for both small samples and wafer samples
3Device complexity
If only one chamber is used, then the device structure is simpler, but the analysis speed and efficiency for multiple sample types deteriorates
Solution Approach 1:
The system segments sample analysis into parallel processing streams through separate chambers, allowing simultaneous analysis of different sample types without sequential bottlenecks, thereby improving overall analysis throughput and efficiency

AI summary
A sample analysis apparatus includes a first chamber that performs a first heating process for heating a small sample and a second chamber including a second chamber housing in which a second heating process for heating a wafer sample is performed. The first chamber includes a first chamber housing in which the first heating process is performed, a first support that supports the small sample, a first heating device that heats the small sample, an accommodation housing in which the small sample is accommodated, a sample tray arranged in the accommodation space, sample container configured to store the small sample, and a transfer module configured to transfer the sample container and the small sample from the accommodation housing to the first chamber.
