Now, has been put into use for the manufacture of PSS dry etching device is approximately 280, of which 200 is in 2011 or 2012 installed. The first is the sapphire substrate manufacturers; second is the purchase of a standard wafer, to PSS LED manufacturers; third is the purchase of the substrate, forming a patterned after the sale of professional PSS manufacturer.. In Emergency Light Manufacturers the 50mm wafer for example, PSS manufacturing yield is usually 80 ~ 93%, but for 100mm wafer, the finished product rate is only 40 70%. However, the leading LED design technology changing field presents different trends.
Plasma etching is on a substrate is patterned to define on the photoresist layer processing, thus produced the mask alignment tools and stepping machine needs. But the mask alignment tool is difficult to meet the PSS requirements of the resolution, the resolution while stepping machine can meet the requirements, but does not cause a fracture or crack under the premise of wafer size patterns depict problems arise.
LED want to be successful, it must reduce the cost, also must improve the performance and uniformity, make the production of LED along the traditional semiconductor ideas forward, improve the attention to detail. First, because of the amount of light emitted from a single LED greatly increased, so the need for the decrease in the number of LED.
Welcome to negotiate.., Ltd. On the other hand, also have a company intends to reduce the amount of equipment investment, through the purchase of the most inexpensive equipment, so that the manufacturing cost is minimized. is one of The LED lighting products supplier in Shenzhen City.).


. But from the point of now, the majority of enterprises (including most of Chinese enterprises have begun to choose the former. Interesting is veteran of the semiconductor equipment company and not gets involved in this market.
In 2011 before the excessive investment
In the next 5 years, the production of LED will continue to expand, so, why production equipment market has peaked rebound? This is because 2010 and 2011 saw a massive overinvestment.
It is expected that by 2018, LED semiconductor material to the area will increase to 4 times in 2012, revenue will reach $17000000000. In the next 6 months, including " nano imprinting transfer ", Copper Tube Heat Sink a variety of commercially available solutions appear estimation will improve large diameter wafer yield, reduce the cost of PSS. With $1900000000 in 2010, $1700000000 in 2011 compared to 2012 market dimensions, the $600000000.

Shenzhen Gleming Photoelectric Technology Co. The use of patterned sapphire substrate (PSS: Patterned Sapphire Substrate) can improve the brightness. After that, the size of the market will continue to shrink, becoming basically rely on buy (replacement) needs to maintain market.
At present, improving PSS production enterprise has three kinds. However, at present before treatment using LED production equipment market is not up to two years before the scale. The main reason is that Chinese government subsidies to the MOCVD equipment, to ensure that the market position of enterprises try their best to invest. These enterprises will be conducted in the second half of 2013 to 2014, the LED investment, production equipment industry will achieve a significant (but limited growth). In 2009, for different process using the same equipment enterprise LED help, LED production of professional equipment debut. Secondly, compared with current technology, LED product life significantly extended, without the need for 1 year to replace the one or two bulbs, change 10 years 1 times can be.
In the past, the LED industry has always been in accordance with the requirements of LED, the standard exposure device and etching device with little modification, to adjust, after again installation to be used.
In the purchase of production equipment, in order to reduce the equipment cost (COO), one part enterprise investment is reliability, uniformity and high performance equipment.
The popularity of PSS plasma equipment demand
Other equipment market and supply and demand differences existed in the MOCVD equipment market, 2012 sales than in 2010 and 2011. Only a year of much time, PSS has accounted for the whole world LED sapphire substrate by nearly 80%, spawned the PSS wafer plasma etching equipment needs.We primarily supply: LED light tube, LED panel lights, LED down lights, LED tube lighting, and LED fluorescent lamp. But most companies are afraid flower briefly as the broad-leaved epiphyllous, and survive enterprises could not buy new equipment, but through the acquisition of failed businesses to increase productivity. But it will also become the LED industry the last large-scale investment. Although sales will also be in 2019 peaked around, but by the following 2 factors, then estimates will gradually shift to reduce.
At present, the LED in general lighting applications has not yet universal, but it is expected that by 2018, more than 50% of the lamp holder will support LED, market sales of lamps will also have more than 80% for LED lamp. This will make the replacement LED market substantially and permanently deceleration. As of 2010, only a few Chinese companies involved in LED production equipment in the field, but have now increased to 70. A 2012 estimate will be maintained at this level. In order to realize the scale advantage, it takes a higher degree of automation, production management software project management, statistics, as well as �box to box " system in order to achieve the aim of evolution
