Solution Overview
Problem
Current probe apparatuses for testing semiconductor devices lack effective means to ensure proper contact and temperature control during electrical characterization, which is crucial for high-speed and complex memory operations.
Innovation Solution
A testing device with a socket made of thermal conductive material, such as copper, and a cover with a circuit board and opening that allows direct observation and contact with the device under test, along with a thermal adjuster to control the device's temperature, is used in conjunction with a probe apparatus that includes a manipulator and monitoring device for precise testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional probe apparatus is used for testing semiconductor devices, then the testing process is simple, but proper probe contact and temperature control cannot be ensured
Solution Approach 1:
The testing device is segmented into distinct functional modules: a socket for mechanical support and electrical connection, a cover with integrated camera for observation, a thermal adjuster for temperature control, and a probe station for precise probe positioning. This segmentation allows each component to be optimized independently while maintaining overall system reliability for probe contact and temperature control.
Solution Approach 2:
A camera system is introduced as an intermediary component that enables visual monitoring of probe contact with the device under test. The camera captures images through the cover, allowing operators to verify proper probe contact without direct visual access, thereby improving contact reliability while adding minimal complexity to the testing apparatus.
2Temperature
If thermal control is added to the testing device, then temperature control capability is improved, but device complexity increases
Solution Approach 1:
The thermal adjuster is merged with the existing socket structure, allowing temperature control functionality to be integrated into the mechanical support component. This combination enables temperature control without requiring a completely separate thermal management system, thereby improving temperature control capability while minimizing the increase in overall device complexity.
Solution Approach 2:
The socket is designed to serve multiple functions: mechanical support for the device under test, electrical connection through contact pads, and thermal control through the integrated thermal adjuster. This multi-functionality reduces the need for separate components, allowing temperature control to be added without proportionally increasing device complexity.
3Measurement precision
If direct observation of the device under test is enabled, then probe contact verification is improved, but device complexity increases
Solution Approach 1:
A camera system is introduced as an intermediary that enables indirect visual observation of the device under test and probe contact. The camera is positioned to capture images through the cover, allowing operators to verify probe contact precision without creating direct optical access, thus improving measurement verification while adding a single modular component rather than redesigning the entire testing apparatus.
Solution Approach 2:
Instead of providing direct visual access to the device under test, the camera creates a visual copy (image) of the contact interface. This optical copy allows operators to verify probe contact precision remotely, improving measurement verification capability while maintaining the enclosed structure of the testing device and adding minimal complexity through the camera component alone.
