Martini Tech offering GaN MOCVD on sapphire substrates

Martini Tech Inc of Tokyo, Japan has started to offer a new gallium nitride (GaN) metal-organic chemical vapour deposition (MOCVD) service on sapphire substrates for LED applications.

Founded in 2013, Martini Tech offers microfabrication services including micro-electro-mechanical system (MEMS) design, development and foundry, sapphire wafer patterning, nanoimprint mold manufacturing (using materials such as silicon, nickel and quartz), nanoimprint replica on film, GaN on patterned sapphire substrates (PSS) deposition by MOCVD, and sputtering deposition services (with more than 120 different materials available).

Widespread adoption of LEDs has so far been hindered by factors including relatively high price and lower light output compared with traditional incandescent light bulbs, notes Martini Tech. One of the most promising techniques for improving the light output of LEDs involves the deposition of a thin GaN epitaxial layer on a patterned sapphire substrate (PSS), adds the firm.

The service offered by Martini Tech includes MOCVD of undoped GaN and of n- or p-doped GaN for high-quality highly ordered crystalline layers up to 5µm thick.
