一般說明

Tantalum nitride etchant is a high purity etchant systems for precise, clean etching of tantalum, tantalum nitride, and tantalum oxide thin films and resists in electronics applications.

應用

在电子应用中可作为精确清洁地蚀刻钽、氮化钽和氧化钽薄膜和防蚀涂层的蚀刻溶液。

特點和優勢

25°C 时腐蚀速度为 70-80Å/秒。与金正性或负性光致抗蚀剂共同使用。用去离子水冲洗。

準備報告

  • Etch times vary depending on material type (Ta, TaN, or Ta2O5) and purity.
  • Dilute with water or lower the temperature to achieve a lower etch rate. Adding 1 part water to 2 parts etchant or reducing the temperature 10 °C will approximately reduce the etch rate by 50%.
  • Parts to be etched should be placed in etchant solution with mild to moderate mechanical agitation.
  • Tantalum Etchants contain hydrofluoric acid and will attack silicon oxides, titanium, nickel, aluminum, and chromium.
  • Gold would be the ideal etch stop. You might also succeed with tungsten
  • Rinse with Deionized water.
