HICERAM Wafer

Overview

HICERAM Wafer

NGK's HICERAM Wafer consists of 99.99% high purity alumina, enabling translucency, high insulation, and high strength. Large sizes (up to 12 inch) and variant shapes using NGK's original Mold-cast forming are available.

Application​

Support Wafer (W/ or w/o Through Vias)​

Superior translucency, thermal conductivity and stiffness

  • Superior chemical resistance by high purity
  • The high degree of arrangement of through vias on the HICERAM wafer is provided by applying mold casting.
  • Size available up to φ300mm or 300mm
  • High transparency, UV to IR
  • High strength equivalent to sapphire.

Interposer substrate​

Thin core material for package substate for superior stiffness and low dielectric loss

Interposer substrate​

Setter for firing​

  • High purity, does not stain the inside of the furnace​
  • Space saving in the furnace available by thin setter.​
  • Infrared transmission, enabling uniform firing and improve firing efficiency.

Other applications​

HICERAM material suitable for components and tools requiring high strength and chemical resistance. (HICERAM is superior to sapphire in availability of large sizes and various shapes)
