Rewritable RF Tag Layout for Semiconductor Authenticity Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for individual identification and management of semiconductor apparatuses, such as using radio tags, are limited to checking manufacturing history and do not facilitate individual management or progress management in units incorporating the semiconductor apparatus or final products.
Innovation Solution
A semiconductor apparatus with a first radio tag installed on its housing that allows rewriting from outside, positioned away from heat generators to prevent information loss or damage, enabling individual and progress management through radio communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a radio tag is mounted on a semiconductor apparatus for individual identification, then individual identification information can be checked, but the radio tag cannot be utilized for individual management or progress management in manufacturing processes
Solution Approach 1:
The radio tag is designed to store multiple types of information including individual identification information, unit assembly information, and manufacturing progress information. This multi-functional capability allows the same tag to be used for various management purposes throughout the product lifecycle, from individual identification to tracking manufacturing progress and enabling comprehensive individual management of semiconductor apparatuses and their containing units
2Ease of manufacture
If printed characters or labels are used for individual identification, then visual identification is possible, but the identification becomes impossible when characters disappear or labels are detached
Solution Approach 1:
The patent replaces mechanical/visual identification methods (printed characters and labels) with an electronic radio frequency identification system. The radio tag stores individual identification information electronically and can be read wirelessly, eliminating the problems of fading, detachment, and illegibility associated with printed and label-based identification while maintaining ease of manufacture through simple tag attachment
3Area of stationary object
If the radio tag is positioned near heat generators, then space is saved, but the tag information may be lost or damaged due to heat
Solution Approach 1:
The patent segments the housing into distinct functional zones: a first region containing heat-generating components and a second region containing the radio tag. This spatial segmentation isolates the heat-sensitive tag from thermal damage while maintaining compact overall housing design, effectively managing both space utilization and thermal protection
