Chip Socket Probing Window for High-Speed DRAM Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional equipment for testing high-speed DRAMs faces challenges due to long transmission paths, which cause noise and distortion, making it difficult to accurately test and analyze these devices.
Innovation Solution
A chip socket with a fastener featuring a probing window surrounded by side walls with a first angle less than 90 degrees and varying opening areas, allowing a probe to contact the chip directly through the window, reducing signal transmission paths and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional testing equipment is used to test high-speed DRAMs, then the testing system is simple and easy to operate, but the transmission path becomes long causing noise and distortion
Solution Approach 1:
The patent introduces a vertical dimension by creating a probing window through the fastener structure, allowing the probe to access the chip surface from above rather than through lateral connections. This dimensional change enables direct vertical probing, dramatically shortening the transmission path and eliminating noise issues associated with long lateral transmission paths in traditional testing equipment
2Measurement precision
If a probing window is added to the fastener to allow direct probe contact, then transmission path length is reduced and noise is minimized, but the device structure becomes more complex
Solution Approach 1:
The fastener structure is designed to serve multiple functions: it provides mechanical clamping force to secure the chip, creates a protective enclosure around the chip, and incorporates a probing window to enable direct electrical access. By integrating these diverse functions into a single component, the patent avoids the need for separate clamping mechanisms and probing structures, thereby reducing overall system complexity while achieving direct probe contact
Solution Approach 2:
The patent merges the clamping function and the probing access function into a single integrated fastener structure. The fastener body simultaneously provides mechanical retention through its clamping arms and creates the probing window opening, combining what would traditionally be separate components into one unified element, thus simplifying the overall device architecture

AI summary
The present application discloses a chip socket for testing a semiconductor chip. The chip socket includes a pedestal and a fastener. The pedestal accommodates a chip to be tested. The fastener includes a top body and a base body. The top body includes a probing window, wherein a first opening area of the probing window at an outer surface of the top body is larger than a second opening area of the probing window at an inner surface of the top body. The base body is attached to the pedestal and locked to the top body when the top body covers the base body and clamps the chip. When the top body covers the base body, the probing window reveals a surface of the chip, allowing a probe to contact the surface of the chip through the probing window.
