摘要

Micro LED 是一种超小型 LED，每个 LED 独立工作，具有高亮度、出色的对比度、宽色域和其他出色的视觉特性。我们利用专有的 PR（光刻胶）扩展技术开发了微型 LED 芯片的转移技术。这种独有的 PR 扩展技术利用半导体光刻工艺，实现了微型 LED 芯片之间的间距转换，并在亚微米尺度上保持了芯片转移的高精确度。这种创新的转移技术实现了微型 LED 芯片的高密度集成，有效降低了单个芯片的成本，成为微型 LED 市场快速增长的主要推动力。

Pitch conversion by photoresist expansion transfer for micro LED

Micro LED is an extremely small-sized LED where each individual LED operates independently, providing high brightness, excellent contrast ratio, wide color gamut, and other outstanding visual characteristics. We have developed the transfer technology for micro LED chips using our proprietary PR (photoresist) expansion technique. This exclusive PR expansion technology, leveraging semiconductor photo processes, enables pitch conversion between micro LED chips and maintains a high level of accuracy in chip transfer at a sub-micron scale. This innovative transfer technology allows for high-density integration of micro LED chips, effectively reducing the cost per chip, and serving as a key driver for rapid growth in the micro LED market.

期刊介绍： The Journal of the Society for Information Display publishes original works dealing with the theory and practice of information display. Coverage includes materials, devices and systems; the underlying chemistry, physics, physiology and psychology; measurement techniques, manufacturing technologies; and all aspects of the interaction between equipment and its users. Review articles are also published in all of these areas. Occasional special issues or sections consist of collections of papers on specific topical areas or collections of full length papers based in part on oral or poster presentations given at SID sponsored conferences.
