Hydrogen silsesquioxane (HSQ) is a highly specialized material used in nanofabrication, particularly in electron beam lithography (EBL). Its exceptional resolution, high sensitivity, and superior etch resistance make it an ideal choice for semiconductor manufacturing, photonics, and microelectromechanical systems (MEMS).
For industries requiring high-purity HSQ, is a trusted supplier. With a strong commitment to quality and precision, DisChem provides specialty chemicals, including HSQ, to meet the demands of cutting-edge research and manufacturing.
What is Hydrogen Silsesquioxane?
Hydrogen silsesquioxane is an inorganic polymer composed of silicon, oxygen, and hydrogen atoms. When exposed to an electron beam, HSQ undergoes cross-linking, transforming into an insoluble material that allows for precise nano-scale patterning. This characteristic makes it a highly effective negative-tone resist in EBL.
Unlike traditional organic resists, HSQ offers exceptional resolution and contrast, enabling researchers and manufacturers to create ultra-fine structures with unmatched precision.
Why Choose HSQ for EBL Negative Resists?
1. Ultra-High Resolution for Advanced Nanofabrication
One of the key reasons hydrogen silsesquioxane is widely used in EBL is its ability to achieve sub-10 nm resolution. This ultra-fine patterning capability is essential for advanced semiconductor manufacturing, photonic device fabrication, and other high-tech applications.
2. High Sensitivity & Contrast for Improved Performance
HSQ responds effectively to electron beam exposure, ensuring a clear distinction between exposed and unexposed areas. This high contrast results in precise, well-defined nano-scale features, making hydrogen silsesquioxane EBL negative resists a superior choice for complex lithography processes.
3. Superior Etch Resistance for Longevity & Durability
Etching is a critical step in semiconductor fabrication, and HSQ resists exhibit outstanding plasma etch resistance. This ensures that patterns remain intact during the etching process, preserving their structural integrity.
