The Investment Excessive Lead To Poor Prospects For The Led Industry, It Needs To Reduce The Cost
Now, LED the way in general lighting has not been popular
, but it is estimated that by 2018, more than 50% of the lamp holder will support LED, the lamps and lanterns of market will also have more than 80% of LED lamp. However, the former treatment use LED production equipment market has not come up to the size of the first two years. With $2010 in 1.9 billion, the 2011 $1.7 billion market scale, compared to the size of the 2012 only $600 million. The enterprise will invest in the second half of 2013, to 2014, LED production equipment industry will achieve obvious (but limited) growth. But it will also be LED industry last large-scale investment. After that, the market scale will continue to shrink, become basic depend to redemption (change) to sustain demand of the market.
It is estimated that by 2018, LED by the area of the semiconductor material will be increased to four times that of 2012; income also will reach the peak of $17 billion. Although sales of around 2019 reach the top, but by the two factors, then estimate will gradually turn to reduce. First of all, because a single LED the amount of light emitted at a greatly increased, so need to reduce the number of LED. Secondly, and technology now, compared with the LED product life greatly extended, no 1 year change one or two bulbs, ten years can change one. This will allow change LED market sharply and permanently reduction.
In the 2011 years before investing too
In the next five years, LED production will continue to expand, so, why production equipment market has top contact bounce? This is because the 2010 and 2011 resulted in a large overinvestment. The main reason is that the Chinese government to MOCVD equipment issue subsidies, the enterprise to ensure market position desperate for investment. By the end of 2010, only a few Chinese companies involved in LED production equipment field, but now have increased to 70. But most of the enterprise may be a flash in the pan, and survive the enterprise estimated also won't buy new equipment, but through the acquisition of failure of the enterprises to increase productivity.
In the past, LED industry has been in accordance with the requirements of the LED, the standard exposure equipment and etching equipment slightly makes the transformation, in the adjustment, to after installation to be of use. In 2009, has for different process using the same equipment LED enterprise with the help of professional equipment production LED shining. Interesting is, the old semiconductor equipment enterprise did not set foot in this market.
In the purchase of production equipment, in order to reduce the equipment occupancy costs (COO), part of the enterprise investment is reliability, homogeneity, along with high performance equipment. And on the other hand, also have enterprise intends to reduce equipment investment, by purchasing the cheapest equipment, make the manufacturing cost minimization. But from now to see, most enterprises (including most Chinese enterprises) have begun to choose the former.
The popularity of PSS that plasma equipment needs to expand
Other equipment market and the supply and demand of the differences between MOCVD equipment market, 2012 years of sales is less than the 2010 and 2011. However, LED LED design technical change but field revealed a different trend. Using graphical Sapphire substrates (PSS: Patterned Sapphire Substrate) can improve the brightness. Only a year time, PSS has accounted for the world LED by nearly 80% of the sapphire substrates, gave rise to for etching PSS wafer plasma equipment needs. Now, have already been put into use for manufacturing of PSS dry etching equipment about 280, there are 200 sets in 2011 or 2012 years of the installation. 2012 estimate will remain at this level.
At present, improve the PSS capacity enterprise have three. The first is a sapphire substrate manufacturers; the second is to buy standard wafer, self PSS change LED manufacturers; the third is the purchase of base plate, patterned after sales professional PSS commerce generation.
Plasma etching in the substrate to determine design after the lithography glue line processing, thus gave rise to mask positioning using tools and stepping machine needs. But mask positioning tool it is difficult to reach the PSS required resolution, stepping machine resolution although can meet the requirements, but not cause fracture or crack under the premise of depicting the size of the wafer when design problems. To fifty mm wafer as an example, PSS manufacturing yield usually is 80 ~ 93%, but for 100 mm wafer, the rate is only forty to 70%. In the next six months, including "nano stamping transfer and various commercial solutions appear estimate will increase large diameter wafer yield and reduce the cost of PSS.
LED to be successful, you have to lower cost, also must improve performance and uniformity, the production of LED along the traditional semiconductor thinking ahead, and improve to the attention of the details. To achieve scale advantage, it takes the higher degree of automation, production management in software project management, statistics, and "box to box" system as the goal to realize evolution.
