Pressing Member Orientation Detection in Planarization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing planarization techniques using coating devices are insufficient for achieving nanoscale planarization on substrates, and the imprint technique faces challenges in visually determining the correct orientation of pressing members, leading to potential damage and errors during the planarization process.
Innovation Solution
A conveyance apparatus is developed to determine the correct orientation of a pressing member before loading it into a planarization apparatus. This apparatus includes a determiner to identify whether the pressing member's surface is the correct side for contact with the substrate, and a controller to manage the conveyance based on this determination, thereby preventing incorrect loading and potential damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a flat plate is used as a pressing member for planarization, then light transmission is enabled for curing the composition, but visual judgment of the upper surface/lower surface state becomes difficult
Solution Approach 1:
The patent applies color markings or visual indicators on the plate surface to enable easy identification of the upper and lower surfaces. The plate includes a first surface with a flat pressing surface and a second surface with visual markers that allow operators to quickly distinguish orientation without compromising light transmission for curing the composition.
2Reliability
If the plate is loaded in a wrong state, then the flat surface may be scratched or damaged during conveyance, but adding orientation detection increases device complexity
Solution Approach 1:
The patent implements preliminary orientation verification by providing visual markers on the plate that allow operators to confirm correct orientation before loading. This simple preliminary check prevents wrong-state loading and potential damage without requiring complex automated detection systems.
3Ease of operation
If manual loading of the plate is used, then operation is simple, but the risk of loading in wrong state increases leading to substrate damage
Solution Approach 1:
The patent uses visual markers such as color differences or patterns on the plate surfaces to guide manual loading operations. These markers provide immediate visual feedback to operators, ensuring correct orientation is achieved during manual loading while maintaining operational simplicity.
Solution Approach 2:
The patent incorporates visual feedback mechanisms through markers and indicators that provide immediate information about plate orientation. This feedback system guides operators during manual loading to ensure correct placement, preventing substrate damage while maintaining ease of operation.

AI summary
A conveyance apparatus loads a pressing member to a planarization apparatus that forms a planarized film made of a material on a substrate by bringing a flat surface of the pressing member and the material on the substrate into contact with each other. The pressing member includes a first surface including the flat surface, and a second surface on an opposite side of the first surface. The conveyance apparatus comprises a determiner configured to perform determination as to whether a determination surface of the pressing member is the first surface or the second surface, and a controller configured to control the conveyance of the pressing member based on a result of the determination by the determiner.
