Silicon wafer as substrate, to solve the shortage of blue LED

Blu ray LED, as Blu-ray and HD DVD two camps for the core, because of the past by the sapphire (Sapphire) substrate is the main restriction of manufacturing base material, make the capacity and quality of LED are subject to considerable challenges.

And a Japanese semiconductor company (Shimei Semiconductor Co.) is claimed to find the silicon wafer as a substrate, to a gallium nitride (GaN) method, in this way, not only made more easily, but also can save cost, but also can prolong the life-span of components. But to 2007 in April will officially begin the application of the products. European friends, you will get a PS3, inside of the blue LED, perhaps by this technique!
