Process development capabilities and expertise in cleanroom, GMP and ATEX applications ensure best process performance as well as safe and reliable manufacturing.


Inline single-side etching

  • Single-side etching without protective films
  • Anti-glare treatment for display applications
  • Acid etching

RENA’s InSide performs inline single side etching of glass, developed and optimized for different applications. The patented technology allows one-side wet surface treatment without the need for protective films for applications reaching from anti-glare treatment for displays to acid etching. The system allows processing of glass substrates of different sizes for a wide range of throughput requirements.


Wet etching for combined laser & wet processing

  • Etching-guided parts release after laser processing
  • For various patterns and feature sizes
  • Proven equipment platform

RENA provides equipment and innovative etching solutions for glass treatment in combination with laser processing. The etching step follows a laser treatment that creates patterns into the glass substrate. The wet process developed by RENA selectively etches the irradiated areas and small pieces of glass can be easily and quickly released from the glass substrate. The technology can be applied to various types of glass and is particularly well suited for thin glass and small features.
