Development of Novel Technology for Production of 0.5 nm Ultra-thin, High-permittivity Gate Insulating films, paving the way for future development of Low Power consumption Devices

February 14, 2011 · Filed Under Green Tech · Comments Off on Development of Novel Technology for Production of 0.5 nm Ultra-thin, High-permittivity Gate Insulating films, paving the way for future development of Low Power consumption Devices 

With widespread use of potable and non-portable consumer electronics, reduction of power consumption is an important issue in every manufacturer’s mind in developing the next product lineup. IC, is the major elements in electronic devices, composed of several hundred million MOS transistors, bearing gate insulating films. Reducing leakage current from the gate insulating film helps in reducing over all power consumption in electronic devices. In order to overcome this hurdle, semiconductor manufacturers, research institutes as well as universities have been working toward development of transistor gate insulating films using high-permittivity materials, expected to reduce the leakage current from the films. The current technology is able to manufacture gate insulating films with an equivalent silicon oxide thickness of 1nm with a future development of 0.65 nm in 2013 followed by 0.53 nm in 2015.

Development of Novel Technology in Reducing Speckle Noise in Projectors and Displays using Laser Light Source by DNP

December 9, 2010 · Filed Under Trendy Products · Comments Off on Development of Novel Technology in Reducing Speckle Noise in Projectors and Displays using Laser Light Source by DNP 

In spite of LED’s advantages over high pressure mercury lamp as a light source for displays, projectors as well as illumination, offering a longer life cycle and reduced power consumption, not to mention the possibility of downsizing the optical components, the laser light source are prone to generate speckle noise which appears as a fine mottled splashing causing scintillation. To overcome this issue, DNP has developed a new technology which is based on multi-recording and light-forming functions of holograms with an aim to reduce speckle noise that is the cause of scintillation. DNP has used volume hologram functions capable of reproducing the same image in the same position no matter which point on the hologram the light beam is projected upon. Read more

Development of Novel Technology for Manufacturing Power Supply Transistor on Flat Surface Material by Fujitsu

December 3, 2010 · Filed Under Green Tech, Trendy Products · 1 Comment 

Fujitsu Laboratories has announced the development of a novel technology that allows manufacturing of power supply transistors on nearly any flat surface including glass, plastic or copper. Through this effort, high breakdown-voltage was achieved by forming a high breakdown-voltage power supply transistor on a target substance by using zinc-oxide (ZnO) material and protecting the transistor’s channel by using a polymer layer. The new technology enables power supply circuits to be manufactured on a wide range of flat surfaces, where it can be applied to such applications as high voltage sensors and piezoelectric devices.

Development of Novel Technology for Accurate Measurement of Hydrogen content in Production of Thin Film Solar Cell

June 23, 2010 · Filed Under Clean Tech, Green Tech · 2 Comments 

Some of key major issues hampering proliferation of silicon based solar cells are their high cost and low performance. The high cost usually associated with the manufacturing cost of these types of solar cells, and the low performance is normally associated with excess hydrogen which is introduced during the process of forming amorphous silicon films on glass substrate. Based on this manufacture of solar cells have turned their attention to thin film silicon solar cells, where a large-size cell panels can be manufactured using only a small amount of silicon, ideal for mass production based on their excellent cost performance. On the performance issue though, up to now there has not been a sufficient developed technology to accurately analyze the hydrogen content that occurs during the manufacturing of thin film solar cells. To overcome this major issue, Dainippon Screen Mfg. Co., Ltd. and Gifu University have successfully developed a novel technology that analysis the characteristics of amorphous silicon films during the production of thin film silicon solar cell panels, paving the way for development of next generation low cost solar cells.
