Aonex technologies, the daughterly company of corporation arrowhead research, concluded agreement about the collaboration with company kyma technologies, which specializes in the carrying out of semiconductor production. The object of the agreement is the materials, which will make possible to reduce the cost of instruments, built with the use of nitride of gallium (GaN). The discussion deals with the so-called dark-blue laser diodes and light-emitting diodes.
Dark-blue lasers is the key element of devices, intended for the work with the optical disk from new generation: HD-DVD and Blu-ray. Series output of these semiconductor devices proved to be nontrivial task and became the reason for delay release such products as, for example, the console sony playStation 3. As far as the light-emitting diodes of the dark-blue color glow are concerned, they are the popular sources of illumination in a enormous quantity of consumer electronics. Moreover, in the opinion the authors in the official press release, during one excellent day they can replace customary incandescent lamps and luminescent luminous sources, since they have higher efficiency and longevity.
On the conditions of collaboration, Aonex will grant Kyma the access to technology of its own development A -Sapph, which makes possible to make the plates of large area, which be suitable for the production of GaN- instruments. As it is asserted, the use of plates with large area can noticeably influence the price of GaN- instruments to the side of its decrease, since a larger quantity of product will be made from one plate.
Plate A -Sapph consists of the hyperfine crystal sapphire (with thickness of less than 500 nm) aluminum fastened to the base layer from polycrystalline nitride. The resulting construction has a coefficient of thermal expansion the practically identical volume, which has GaN. This, and also the high thermal conductivity plate (in comparison with the crystals of sapphire larger thickness), it makes possible to substantially increase the quality of production, to increase the percentage of release for suitable instruments.
