Sapphire Silicon LED Chip Prices Rose in Short Supply

Raw sapphire LED chip silicon ingot (SapphireIngot) since 2009 out of stock after the tide, sapphire silicon (SapphireWafer) prices crashed to rise, the current price of sapphire wafers corresponding period in 2009 increased by 3 times compared to the first quarter of 2010 an increase of approximately 50%, LED packaging and other products also contributed to the price rise. The industry is working to ensure that the price and quantity available, the phenomenon of terrorism by the end of 2010 wafer demand continued.

According to the industry, the global sapphire silicon ingot production in the two former American Rubicon and Russia Monocrystal into the first three quarters, both to raise prices to make sapphire wafers, LED chips and packaging prices are not stable. Sapphire wafer LED chips account for about 10% of the cost of materials, production of the chip is very important raw materials.

When 2008 is still an oversupply of silicon ingots, LED industry in 2009 when competing production, which leads to the current situation in short supply. Rubicon2009 can produce cut into 2-inch sapphire wafers 5000000 silicon ingot, 2010 is expected to expand production capacity to 6.5 million scale, but to the end of this program may be achieved. Monocrystal2009 annual production capacity of about 4 million scale, to 2010 only increased by 500,000 to 4,500,000 scale.

The aforementioned two companies to order the production of silicon ingots into wafers day display (IljinDisplay), CrystalOn Korean companies, such as the burden of raw materials is rising, past the sapphire silicon ingot price premium pass all parts of the wafer industry Samsung LED and LGInnotek other LED industry, along with the recent price increase of silicon ingots purchase price, on a quarterly basis to perform lowered price of the raw material cost increases display industry in South Korea is quite rare, it shows accompanied sapphire and silicon ingot out of stock hike the price situation is quite serious.

LED chip and package price hike, Samsung Electronics (SamsungElectronics), LG Electronics (LGElectronics) and other effects of the recent increase in industrial production and the proportion of downstream LEDTV quite far-reaching, in addition to the LED lighting industry is in trouble spot, although not the backlight module LED, Samsung LED from May to provide dealers, agents and other LED lighting products have been part of the 30% price hike. Since the sapphire wafer prices, production of LED lighting unit also will increase.

Industry related personnel, said the past metal organic chemical vapor deposition (MOCVD) number of devices and LED production are closely related, but now is based on the number of silicon ingots, wafers to depend utilization rate is currently investing to increase production capacity by expanding MOCVD is meaningless.
