China-Made Alternative Products

Chinese alkali-free display glass can be selected by strain point, CTE, sheet generation, thickness, surface quality and thermal-shrinkage requirements, then cut or processed into smaller semiconductor substrates.

Recommended matching criteria:

  • Chinese alkali-free substrate glass
  • Large-sheet or cut-to-size supply
  • Thermal-cycle and thin-film process validation
Target modelCritical parametersCandidate gradeSample testingBatch qualification
Customization and Processing
  • Round wafers, square panels, windows and custom outlines
  • Precision cutting, edge grinding, chamfering and laser processing
  • Single- or double-side polishing, thinning, cleaning and marking
  • TTV, warp, roughness, dimensional and optical inspection to agreed criteria
Qualification Note
Important: “Alternative” means a candidate selected for the same application target. It does not mean an automatic drop-in replacement or identical composition. Final acceptance is based on agreed specifications, samples, test reports and process verification.
