Inkjet Printing Image Conversion for Semiconductor Layer Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inkjet printing methods face distortion and loss issues when forming images on curved lines due to the creation of gray areas in black and white image files, particularly in semiconductor device manufacturing where precise layer formation is required.
Innovation Solution
The method involves converting shape drawings into vector images using primary colors and their equivalents, applying a color table and boundary table to ensure adjacent colors do not produce gray, and then converting these images into raster images with adjusted resolutions for inkjet printing, ensuring only black and white output without distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If shape drawings are converted to raster images with multiple colors for inkjet printing, then color information is preserved, but gray areas are created causing distortion and loss on curved lines
Solution Approach 1:
The patent extracts and removes color information from the image data, converting multi-color images to black-and-white binary images. This extraction eliminates the harmful gray areas that cause distortion on curved lines while preserving the essential structural information needed for precise inkjet printing in semiconductor manufacturing.
Solution Approach 2:
The patent changes the parameter of image color depth from multi-color to black-and-white binary. By transforming the image from containing multiple color values (including problematic gray areas) to only black and white pixels, the method eliminates distortion on curved lines while maintaining sufficient information for accurate pattern formation.
2Manufacturing precision
If black and white image files are used for inkjet printing, then distortion and loss on curved lines are prevented, but color information is lost
Solution Approach 1:
The patent creates a simplified black-and-white binary copy of the original multi-color image. This copy retains the essential geometric and structural information needed for precise inkjet printing while deliberately omitting color data that would create harmful gray areas and distortion on curved lines.
3Loss of information
If multiple colors are disposed adjacent to each other in vector images, then color representation is improved, but gray areas are created when converted to black and white images
Solution Approach 1:
The patent extracts only the binary black-and-white information from multi-color vector images, deliberately removing color data that would create gray areas during conversion. This extraction process preserves sharp boundaries and prevents distortion while maintaining sufficient information for accurate pattern formation.

AI summary
An inkjet printing method includes: preparing a shape drawing; creating an image for an inkjet printing based on a color table or a boundary table; applying the image for the inkjet printing to an inkjet apparatus; and performing the inkjet printing based on the image by the inkjet apparatus, where the creating the image for the inkjet printing includes converting the shape drawing into a vector image, converting the vector image into a raster image, and converting the raster image into the image for the inkjet printing which is a black-and-white image.
