- Key Products/Technologies
- Semiconductor blank masks are raw materials for photomasks used in realizing patterns of hundreds to tens of nanometers for highly integrated circuits like DRAM. The company offers a diverse product lineup, including Binary (BIN) blank masks, KrF and ArF Phase Shift Masks (PSM), and hard mask blank masks. Key capabilities include controlling substrate, metal film, and resist film properties for improved resolution. Extreme Ultraviolet (EUV) blank masks are advanced products manufactured by stacking absorber-based alloys on thin multi-layers at nanometer scales. S&S TECH is actively researching and developing four types of EUV blank masks, including BIN, Hard Mask (HM) BIN, HM PSM, and Thin BIN types.Semiconductor blank masks are raw materials for photomasks used in realizing patterns of hundreds to tens of nanometers for highly integrated circuits like DRAM.

- FPD (Flat Panel Display) blank masks are raw materials for photomasks used in manufacturing liquid crystal devices for large displays such as TFT-LCDs and OLEDs. These masks come in various sizes depending on the final product and are also referred to as large-area blank masks. The company focuses on developing next-generation display products, including TM and PSM blank masks, and 10th-generation large-area blank masks. EUV pellicles are critical components for protecting photomasks, with 400W EUV pellicles demonstrating a transmittance of 91.2% and capable of producing 25,000 wafers. Efforts are underway to secure technological superiority through the development of next-generation pellicles capable of withstanding over 800W.FPD (Flat Panel Display) blank masks are raw materials for photomasks used in manufacturing liquid crystal devices for large displays such as TFT-LCDs and OLEDs.
