Development of Pressure Sensitive Adhesive Materials with Structurally Controlled Polysilsesquioxanes for MicroLED Transfer Application

다국어 초록 (Multilingual Abstract)

MicroLEDs with individual arrays of LEDs of microscopic LEDs forming individual pixel elements have been touted as next generation displays with exceptional contrast, response times, and energy efficiency. However, expensive fabrication methods have limited their commercial viability and manufacturing throughput. Recently, transfer based fabrication methods which utilize a stamp to adhere individual microLEDs on sapphire substrates has been proposed. In this presentation, I will talk about the development of inorganic-organic hybrid silsesquioxanes with controlled ladder-like structure for application as transfer stamp material for microLEDs, including the effect of silsesquioxane structure, organic functional group, and organic functional group composition on the adhesive properties for possible application in microLED transfer application.
