AGC EN-A1 Alkali Free Boro-Aluminosilicate Glass

Download this information as a pdf adobe acrobat pdf

 

Abrisa Technologies offers Asahi Glass Corporation (AGC) EN-A 1 material, a highly transmissive, alkali-free thin boro-aluminosilicate glass that is ideal for highly sensitive bio-photo detection applications, high through­put sensor applications and as enhancement glass for thin displays and cover glass for micro arrays.

 

Its coefficient of thermal expansion (CTE) of 38 x 10-7 is well matched to silicon, making it an ideal and economi­cal choice for use as a glass polishing substrate for the thinning process (back grinding) of semiconductor chips supporting low profile electronic device manufacture.

 

Key Features:

  • Alkali-free
  • CTE well matched to silicon
  • Standard thicknesses 0.3, 0.5, 0.7mm
  • Sizes up to 25″ x 20″ (635mm x 508mm)
  • High Transmittance from 400 – 2300nm
  • Good chemical resistance
  • Low fluorescense at genomic excitation wavelengths

Applications:

  • Image sensor windows
  • Cover glass for micro arrays
  • Display enhancement glass
  • Biosensors
  • Glass for semiconductor thinning
  • Low weight, reduced profile designs

Similar CTE trend as silicon
