Moore's law for flip chip technology is dead to dawn

In 2015 the LED industry is very low in a year, especially in the upstream, experienced overcapacity, the chip and the beads on a price fall to bargaining chip and the lamp is almost a very painful process, I believe many people engaged in LED technology as well as I do not have a return such as the feeling, so I felt a year of silent protest!

The autumn of last year, when I was in Japan in 2015 Fukuoka WUPP for wide bandgap Semiconductors forum and the 2014 Nobel physics prize winner Amano Hiroshi Professor, I in this industry again a glimmer of hope, this is my last year to today after a 2016 year tribute to everyone.

When the university or Research Institute, if the electronic or semiconductor department students will repair or solid state physics, semiconductor physics, we know that IC is Moore's law, but because of the curriculum, in this part of compound semiconductor less ink, so few people know that there is a law in the field of photoelectric Heinz LED compound semiconductor the inside of the.

Look at IC's Moore's law:

The number of integrated circuits on an integrated circuit chip doubles every 18 months, and the performance of the microprocessor doubles every 18 months, or by half the price.

As shown in this Law in 2010 after the 20 nanometer process is a bit weak, Moore suffered a severe test, scientists and engineers have struggled to extend the semiconductor Moore's law, to seek a breakthrough in the semiconductor technology?

The key moment there will always be a hero to save the United States, Professor Hu Zhengming is a professor at the University of California at Berkeley distinguished lecture of the semiconductor industry Savior, he invented a FinFET technology, can be reduced to the semiconductor process linewidth of 10 nm to 12 nm process (the gate of the narrow linewidth, processor work faster).

Technical details please see below, when the exposure time limit by others to shrink the linewidth of brains, the first thing he did after solving the problem of leakage of electricity thin crystal, the opposite to the development, the chip structure from the horizontal to the vertical.

This technology not only extends Moore's law, but also allows us to live faster and more convenient in the electronic information age.

To return to our theme for LED's law:

LED price every 10 years will be the original 1/10, the output lumen increased by 20 times, as shown in the following figure.

This law seems to now is to complete the pink of perfection, but the sacrifice of our LED technology work, because Chinese, crazy expansion, 2015 is down to a compound semiconductor and LED technology, due to upstream overcapacity, the homogenization of competition caused by everyone regardless of the cost of the bargain.

Looking forward to the market balance of supply and demand of the day, LED lost the direction, looking back, perhaps LED has not come to a dead end, let me have all contribution to LED's business technology, see how we can change and the turnover of the industry:

Heinz law

After 1993, Dr. Nakamura Shuji invented the first commercial Blu ray LED, LED began to enter the era of color, but the high price of LED, the brightness is not bright, so the application is limited, after seven years of exploration, the industry gradually shifted to Chinese.

As shown below, from 2000 to 2008, LED entered the first golden period, by the early American Luminled company and bright sharp flip chip technology Taiwan dress technology competition, finally because of import technology and laser cutting ITO transparent conductive layer technology, formal technology LED into the era of gain a complete victory, backlight.

From 2008 to 2014, is a relay race, LED center by the Taiwan China slowly transferred to the mainland, a series of technical engineers from Taiwan to the mainland, the patterned substrate PSS technology, automation equipment into semiconductor, sputtering transparent conductive layer (sputter ITO), significantly reduce the optimization and cost structure of the epitaxial epitaxial (especially the United States Veeco MOCVD equipment import, let Taiwan engineers lose value, and also reduce the personnel and technology, cost and boss) reflecting electrode structure optimization and so on, Taiwan and the mainland by division of labor relations into a competitive relationship.

And compared to the plight of IC encountered in 2010, Professor Hu Zhengming has made technological breakthroughs in the IC industry to maintain orderly and healthy competition.

2105 may be the lowest one year for LED, as Europe and Japan and South Korea Taiwan enterprises because China, irrational price competition, resulting in a sense it would be better to return to the LED industry, their investment in LED technology is almost a drop in the bucket, a lot of enterprises almost have to give up the chicken ribs off hand, so since 2014 CREE announced issued 303 lumens tile technology, Europe and Japan and South Korea Taiwan enterprises have little voice, relative, Chinese mainland enterprises is much more active, China mainland enterprises in 2015 of Heinz law's contribution is to sacrifice profits for the purpose of extending, and not as dominant and the contribution of IC to the industry technology industry.

LED chip technology growth does not contribute much to his law, if the contribution is only about Chinese soldier ants the packaging industry.
