700PRS Series

Lefiq-700PRS Series (710 PRS, 720PRS, 730PRS), Positive Photoresist Stripper

Description:

Lefiq-700PRS Series are pre-mixed combination of two photoresist strippers (similar to Lefiq-600PRS) with a pH close to 14. The effective molecular structure of this product series not only allows stripping the photoresist films, it removes all small trapped particles within the device trenches.

Application:

These photoresist stripper chemical products could be used in cleaning of any electronic devices with thick photoresist layers where metal lines which are sensitive to pH (such as Aluminum) are absent.

Cleaning process:

  • Process temperature has to be maintained between 65 to 70 degrees C.
  • Mechanically agitating the cleaning solution or performing the cleaning process within a Sonication system is highly recommended.
  • It must be noted that the effective concentration of these photoresist stripper products increases from Lefiq-710PRS to Lefiq-730PRS.

Lefiq-700PRS (Positive Photoresist Stripper)

Lefiq-700PRS Series are very effective positive photoresist strippers operating at low pH and low cleaning process temperature. They can be used for stripping both thin and thick films of photoresist. The unique chemical formulation of Lefiq-700PRS Series effectively clean high-resolution lines without undercutting the photoresist layer. The effective cleaning power of Lefiq-700PRS Series increases from 710PRS to 730PRS line of products. For more information, please contact us.
