Description

4-Benzoyl-2,6-Dibromo-1,3-Phenylene Bis(6-Diazo-5,6-Dihydro-5-Oxonaphthalene-1-Sulphonate) is a specialized diazonaphthoquinone (DNQ) derivative, a critical class of compounds in advanced photoresist chemistry. Its value lies in its ability to act as a highly effective photoactive compound (PAC), generating precise chemical changes upon exposure to specific wavelengths of light. This makes it an essential component for manufacturers in the semiconductor and microelectronics industries, where it is used to create the intricate circuit patterns essential for modern chips and displays.

Application

• Semiconductor Photoresists: Primary application as a photoactive compound (PAC) in chemical amplification and g/i-line photoresist formulations for integrated circuit (IC) fabrication.
• Advanced Packaging: Used in photoresists for wafer-level packaging (WLP), fan-out wafer-level packaging (FOWLP), and through-silicon via (TSV) processes.
• Flat Panel Display (FPD) Manufacturing: Key component in photoresists for patterning thin-film transistors (TFTs) on LCD and OLED display panels.
• Micro-Electro-Mechanical Systems (MEMS): Employed in photolithography steps for creating precise mechanical and electromechanical microstructures.
• Printed Circuit Board (PCB) Fabrication: Used in high-resolution, liquid photo-imageable (LPI) solder masks and etch resists.
• Optical Lithography Research: Serves as a research chemical for developing next-generation photoresist materials with improved sensitivity and resolution.

Quality Control

Every batch of our 4-Benzoyl-2,6-Dibromo-1,3-Phenylene Bis(6-Diazo-5,6-Dihydro-5-Oxonaphthalene-1-Sulphonate) is manufactured and tested under strict quality management systems. We provide comprehensive analytical data to ensure the material meets the stringent purity and performance requirements of the semiconductor industry. A detailed Certificate of Analysis (COA), including assay (HPLC), identity confirmation (IR, NMR), and critical impurity profiles, is supplied with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under dry, inert conditions (e.g., nitrogen or argon atmosphere) and away from direct light exposure to maintain stability and prevent decomposition.
