MgO (100) substrate, 5x5x0.5 mm, 1SP - MGa050505S1

MTI

Specifications

  • Size:           5 mm  x 5 mm x 0.5mm +/-0.05 mm
  • Orientation:  <100> +/-0.5° on surface, <010> +/-1°on edge
  • Polish:         One side EPI polished by CMP technology with minimum sub-surface damage
  • Packing:      The substrate is packed with 100 grade clean plastic bag under 1000 class clean room
  • Precautions:  MgO is sensitive to moisture, and must be stored in vacuum box.
  •        
Warning:  MgO crystal was grown by arc melting method and natural cooling.  It is difficult to get uniform perfect crystal bulk. 
Please check rocking curve for each substrate before depositing film. We can provide rocking curve service at $50 each if someone has no capability to inspect.
