This research includes developing advanced processes on multiple commercial micro- and nano-fabrication tools manufactured in the UK by Oxford Instruments Plasma Technology that can be transferred directly into companies for production.


Announced by UK Minister for Universities and Science David Willetts at an event this week in London, the award from the Engineering and Physical Sciences Research Council (EPSRC) will support work undertaken by researchers from the University of Glasgow’s College of Science and Engineering in collaboration with Oxford Instruments Plasma Technology, the National Physical Laboratory, the National Microelectronics Institute and Gas Sensing Solutions.


The funding will allow the University to purchase new equipment including several Oxford Instruments Plasma Technology’s tools to etch semiconductor materials and deposit electrically insulating layers, techniques used to fabricate high performance electronic and optical devices including transistors, LEDs and lasers.


The equipment will support a range of new research projects including:


The development of more efficient power electronics, which could improve the lifespan of batteries in many consumer electronic devices as well as reduce their carbon footprint Improving the efficiency and durability of solar collection technology, creating a dramatic reduction in the cost of large- scale exploitation of solar energy


The development of a ‘superspectral’ imaging camera which will integrate visible, infrared and mid-infrared imaging sensors on a single chip for the first time, with applications for security and medical sensing technology


Douglas Paul, Director of the University’s James Watt Nanofabrication Centre, who led the funding bid, says, “Glasgow has a long history of successful exploitation of research which goes all the way back to James Watt’s invention and commercialisation of the condenser for the steam engine, and this award will help us continue that proud tradition. We’re pleased that the EPSRC accepted our funding bid and we’re looking forward to helping support the UK’s efforts to become a more energy-efficient nation.”


Minister for Universities and Science David Willetts adds. “For Britain to get ahead in the global race we have to back emerging technologies and ensure our universities have the latest equipment. This capital investment will help scientists make new discoveries and take their research through to commercial success. It will drive growth and support the Government’s industrial strategy.”


LED chip price currently


stable but may fall in H2 2013 In the long term, only invalid production capacity in China can help the LED industry to return to supply and demand balance

In accordance with statistics in Gold membership reports of LEDinside, Green Energy Division of the Global market research firm TrendForce, thanks to strong demand in the global LED lighting market in the first half of this year, the utilisation rate of MOCVD machines that the major chip manufacturers have installed and debugged shows rising trend.


The chip price has been stable this year, but with the increasing capacity of chip manufacturers, it remains to be seen whether the LED chip price will be falling in the second half of this year. But in the long term, only invalid production capacity in China can help LED industry to return to supply and demand balance.


Chinese Major LED Chip Manufacturers MOCVD Utilisation Rate


The rise of LED lighting market has directly stimulated the upstream chip market to achieve rapid demand growth this year, the Chinese chip makers who have originally specialised in the production of display applications actively adjust product strategy and improve the ratio of lighting chips in the product segment.


HC SemiTek and Silan Azure used to have chip for LED display as core business, now they adjust production capacity in response to increasing market demand for LED lighting chips, all newly added MOCVD equipments are put into use for the production of lighting chips. Overall, the growth in display market has slowed down since 2012, more competitive, more difficult to make profit for manufacturers, which also is one the reasons why the chip manufacturers switched to produce LED chips for the lighting application.


Sanan Optoelectronics totally owns 149 units of MOCVD, currently, more than 90 percent of its MOCVD machines have completed the testing stage and have been put into operation, and utilisation rate also exceeds 80 percent.


ETI has 92 units of MOCVD as of 1H13, 45 units have been put into use for mass production, both its installation volume and mass production amount are the second in China. Due to less MOCVD machines, HC SemiTek’s MOCVD machines and Silan Azure’s MOCVD machines have already fully come into use. Other chip vendors also have achieved some growth in utilisation rate of equipments.


The growth in utilisation rate of MOCVD increases manufacturers’ confidence to expand production; the manufacturers who delayed expansion plan because of poor market also restart the program.


According to the statistics in LEDinside Gold membership report, The number of MOCVDs in China reached 1,013 in late
