First True Bulk
GaN
SCSA, Inc. proudly
announces fabrication of the First True Bulk
GaNcrystals
This is a breakthrough achievement in scsa¡¯s program to develop GaN
substrate fabrication technology.
Fabrication process consists of the following
steps:
Step 1: Bulk GaN boule growth on GaN seed
Step 2 : Slicing of the grown boule into wafers (35 mm diameter GaN boule sliced by a diamond wire saw is
shown)
Step 3 : Polishing of GaN wafers
LED fabricated on SCSA¡¯s bulk GaN substrate. One of the electrodes is placed on top of the LED
structure and the other one is connected to conducting GaN
substrate.
Bulk GaN substrates are not available yet commercially
