OLED PBN Crucibles

OLED evaporation process is a thin-film deposition technique performed under high vacuum environments. During the process, OLED materials held by crucibles are heated by resistance and electron beams to atom vapor in the vacuum chamber and then deposited evenly onto the substrate surface.

In the OLED evaporation process, crucible performance is a crucial factor governing the OLED production yield. The inappropriate crucible will fail to bring the evaporation material up to its required boiling point, resulting in incomplete vaporization that prevents the material from adhering to the surface of substrates. This leads to multiple negative impacts, including time and labor waste, elevated overall raw materials expenses, poor material utilization and low manufacturing yields.

Advantages of Semicorex OLED PBN crucibles

A. Ultra-high purity and negligible impurity contamination under high-temperature operating conditions.

B. Dependable chemical stability, being non-wetting and chemically inert against most metals and small organic molecules.

C. Superior thermal management capability to endure high temperatures and repeated temperature cycling for a long time.

D. Exceptional gas tightness to prevent gas infiltration in vacuum chambers and maintain the evaporation atmosphere pure.

E. Flexible tailored solutions for our OLED PBN crucibles in diameters, height, wall thickness and dimensional tolerances, offering perfect compatibility for various applications.

Applications of Semicorex OLED PBN crucibles

1. Organic light-emitting material deposition

Semicorex OLED PBN Crucibles serve as vessels for RGB organic small-molecule evaporation. The non-stick characteristic of Semicorex OLED PBN Crucibles fully meets organic evaporation standards and ensures consistent thin-film uniformity.

2. Metal cathode source evaporation

These PBN crucibles are extensively used for metal cathode evaporation. PBN can avoid alloying reactions with molten metals, eliminating the defect of traditional metal crucibles being eroded and damaged after contact with metallic sources.
