Product Features 產品特性

  • Hydrogen silsesquioxane dissolved in butyl acetate
    主要成份為氫基倍半矽氧烷溶於醋酸正丁酯
  • High resolution e-beam resist
    高解析度電子束微影阻劑
  • Improved shelf life, as butyl acetate reduces gelling and particle formation
    使用醋酸正丁酯為溶劑以減少結塊及顆粒的形成,有效的改善有效期限
  • Improved stability due to the addition of stabilizer molecules
    添加穩定劑使產品更形穩定
  • Elimination of the presumably carcinogenic solvent MIBK (methyl isobutyl ketone)
    不使用可能致癌的甲基異丁酮(MIBK)溶劑

Note on stability 穩定性說明

Coated substrates can be stored under normal conditions and processed without loss of sensitivity or resolution even after several days. The use of vacuum or inert gas is not necessary.
已塗佈阻劑之基板在正常情況下仍可維持其敏感度或解析度至數日。(無需置於真空或鈍氣環境)。

Contrast curve

Contrast curves of Medusa 84 SiH with a dwell time of 3 days between irradiation and development. Developing with a higher TMAH concentration leads to improved contrast with only a slightly higher dose.

Medusa 84 SiH曝光後靜置3天再進行顯影,以較高濃度TMAH顯影劑僅需些微調整曝光劑量。
