GaN Epitaxy: The Growth Step in the Published Chain

What epitaxy is, in this chain

In the chain the company publishes, epitaxy is the step named for growth on a sapphire substrate: it follows the company's own MOCVD equipment and precedes chip fabrication. The wafer that leaves this step goes forward to chip fabrication, and packaging is the step the chain names after that.

The chain, as the company publishes it

• Equipment: GaN MOCVD systems, the company's founding product line since 2001.
• Epitaxial growth: growth on sapphire substrates, in the company's own reactors.
• Chip fabrication: the step named next in the published chain, between epitaxial growth and packaging.
• Packaging: the final step in the published chain.

The list above reproduces the chain as the company publishes it. The record behind the growth step — the company's own reactors and the generations it has recorded for them — is stated in the company history set out below; what that record establishes for a specific chip or package model is confirmed per model in the enquiry exchange.

The company's own history runs through this step: in 2010 it built a UV LED production line on its own MOCVD equipment and produced 280 nm deep UV LEDs on it, and its published history records its deep UV application products reaching commercialisation in 2012. That record is part of the equipment programme's published history, stated on the company record rather than inferred from the product list.

The growth step in the company's record

The company's published record states this step at programme level: the growth runs in the company's own MOCVD reactors — the founding product line, developed from 2001, with recorded generations in 2002, 2005 and 2007 — and the company's own UV LED production line has run on that equipment since 2010. What that record establishes for a specific chip or package model — which figures are recorded for it, and under what conditions — is confirmed per model in the enquiry exchange, not inferred from the programme history. How the step itself runs, run by run, is the MOCVD process.

Epitaxy capacity, as a purchase

Which purchase a programme is making — components from the company's published chain, or epitaxy capacity of its own — is the first thing an equipment enquiry should state, with wafer format, layer programme and throughput alongside it. An enquiry framed around epitaxy capacity is an equipment conversation, specified per project in that exchange.

Does the company sell epitaxial wafers as a product?

The published catalogue covers chips, packages, modules and MOCVD equipment. The manufacturing chain the company publishes is a separate statement: its own GaN MOCVD equipment, epitaxial growth on sapphire, chip fabrication and packaging — and epitaxy is the growth step that chain names. A requirement framed around epitaxy capacity is an equipment conversation — start it on the equipment page inputs.

Stating an epitaxy enquiry

An enquiry that turns on this step states the wafer format and loading, the layer programme — GaN, AlGaN, or a research stack — the throughput the system must sustain and the facility conditions at the site. What a configuration will grow for that programme is established per project in the configuration exchange.
