What Inex does

INEX Microtechnology Limited is a Newcastle upon Tyne-based compound semiconductor and MEMS contract manufacturer, operating as a private limited company with 11–50 employees. The company provides full-service device development and fabrication services from prototyping through to series production, working in gallium nitride (GaN), indium antimonide, silicon carbide, diamond, and other wide-bandgap and novel materials. It runs a 400m² class 1000 front-end cleanroom and a 150m² class 10,000 back-end cleanroom at the Herschel Annex, Kings Road facility, supported by an in-house multi-disciplinary engineering team and ISO9001:2015 accreditation. The company originated in 2005 as part of the University of Newcastle and transitioned to a commercial enterprise in 2014.

INEX's product portfolio spans five core technology lines: GaN power devices (high-voltage vertical and lateral HEMTs and diodes for DCDC converters, inverters and EV chargers); GaN RF MMICs (low-noise, medium-power and high-power amplifiers for radar and communications, now in high-volume production release); MEMS sensors and actuators (over 50 distinct devices, including accelerometers qualified for space exploration); optical semiconductor devices (application-specific LEDs and photodiodes in indium antimonide and GaN for safety-critical sensing); and novel materials and structures (SiC and diamond electronics, microfabricated vapour cells for atomic clocks, magnetometers and quantum devices). Customers range from major defence prime contractors and blue-chip multinationals to innovative start-ups across aerospace, defence, automotive, space, energy and industrial end markets.

The business model is quote-based B2B contract manufacturing with multi-year engagements. INEX goes to market through a direct, sales-led enterprise motion targeting defence primes and large multinationals with safety- and mission-critical requirements, supported by ISO9001:2015 certification and audited supplier status with major defence primes. Distribution is direct from the Newcastle fab to a global customer base, with marketing primarily through the corporate website, LinkedIn, YouTube, Twitter, Facebook and email. Revenue is generated on a project-by-project, custom-engineering basis spanning feasibility, prototyping and series production rather than via licensed IP or volume wafer pricing.
