Multi-Finger Flexure Jig for Quantum Cell Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in manufacturing miniaturized quantum devices is applying uniform force to objects with small non-uniformities in their contact surfaces, which can result in defects.
Innovation Solution
A multi-finger jig is designed to apply uniform force by having slits that form multiple fingers, allowing each finger to adjust independently to non-uniformities, ensuring a consistent distribution of force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple jig is used to hold an object flat, then the device complexity is reduced, but the manufacturing precision deteriorates due to non-uniform force application
Solution Approach 1:
The jig is divided into multiple independent fingers instead of a single rigid contact surface. Each finger can independently adjust to local surface non-uniformities, ensuring uniform force distribution across the entire contact area while maintaining relatively simple overall structure.
Solution Approach 2:
The jig transitions from a static rigid structure to a dynamic adaptive structure where each finger can flex and adjust independently. This allows the jig to automatically compensate for surface non-uniformities and maintain consistent force application without complex active control systems.
2Device complexity
If a rigid jig is used to apply force, then the device complexity is low, but the manufacturing precision deteriorates when contact surfaces have non-uniformities
Solution Approach 1:
The rigid contact surface is segmented into multiple independent fingers. This segmentation allows each finger to independently respond to local surface variations, maintaining uniform force distribution even when the contact surface has non-uniformities, thereby resolving the contradiction between structural simplicity and manufacturing precision.
Solution Approach 2:
The jig utilizes elastic deformation of the finger materials to change the contact parameters adaptively. When the contact surface has non-uniformities, the fingers flex to different degrees, automatically adjusting the local contact pressure to maintain overall uniformity without requiring complex active adjustment mechanisms.

AI summary
In the manufacture of a quantum cell, multi-finger jigs are used to hold precision masks flat during a photolithographic procedure and or to apply force uniformly over a bonding area during an anodic or other direct bonding procedure. The fingers of a jig are flexible that they can bend sufficiently independently of each other that one finger can accommodate a non-uniformity of a surface to be contacted by the jig so that other fingers remain in contact with other areas of the surface. The fingers can be defined by slits orthogonal to a perimeter of the jig.
