LED industry has undergone big changes. Based on the potential market demands, many companies have mushroomed all over the world in recent years. However, an oversupply comes after the large capacity expansion. What’s worse, due to credit crisis, LED development in European market has slowed down. And it also has influenced Asian LED manufacturers which rely on the external market. As a result, partial manufacturers have seen a slowing increase in their revenues. Despite the troubles, governments still sustainably promote LED lighting. The latest market report p...

Traditionally Gallium Nitride (GaN) LED devices are produced on either sapphire or silicon carbide (SiC) substrates, due to the good crystal lattice matching between the materials and the GaN, with typically 2” or 4” diameter material being used. Significant effort is being made to grow GaN on ubiquitous larger diameter (6” or greater) silicon wafers, a substrate that offers significant substrate cost reduction, together with the ability to process in automated IC production lines. Reasonable estimates are that potential savings on the order of 80% over tr...
