我们的铬蚀刻剂是一种高纯度硝酸铈铵系统，用于铬和氧化铬薄膜精确、洁净的蚀刻。兼容阳性和阴性光致抗蚀剂。我们的铬蚀刻剂通过过滤去除了0.2 微米以上的所有颗粒。 蚀刻温度因薄膜厚度不同而不同。室温下蚀刻时间在15秒至60秒之间。铬蚀刻剂应在通风橱中操作。
硝酸铈铵基蚀刻剂。室温下蚀刻速率为40埃/秒。只需用去离子水冲洗干净即可蚀刻。
铬蚀刻剂是铬基溶液，可从底物移除多余金属。这些蚀刻剂主要用于金属表面处理和电子工业。蚀刻速率为4 mm/s，可用于蚀刻镍、铜和铬基多余金属。[1][2][3][4]

应用

用于室温或高温条件。蚀刻干净，省去中间清洗环节。蚀刻温度随膜的厚度而改变。室温下蚀刻时间在 15 到 60 秒之间。注意，应在通风良好的通风橱内处理铬蚀刻剂。
该产品可蚀刻铝、铬、铜、镍、GaAs。它能表面氧化硅、钽/TaN，但对Si3N4, SiO2, Ti, 和 W表面没有影响[5]

特点和优势

设计用于铬和氧化铬薄膜的精确、清洁蚀刻。与正性和负性光致抗蚀剂均可相容。经 0.2 微米孔过器过滤以去除微粒。

Questions

1–3 of 3 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  3. Does this product etch Ti and TiO2? If so, what is the etch rate?

    1 answer

    1. The chromium etchant, product 651826, is compatible with titanium, meaning it does not etch titanium. While there is no specific information on TiO2, it is assumed that the same is true. The etch rate at 40°C is 40 Å/sec, and the rate will approximately double with every 10°C increase in temperature. Additionally, the rate of stirring or agitation will also increase the etch rate.
