HallTech

HallTech is an emerging technology company with a small, senior team and an explicitly engineering-driven development model. Its team is expanding across plasma physics, materials science, mechanical and electrical engineering, industrialization, metrology, and semiconductor integration, with operations in the Netherlands and the United States. The company is currently moving its technology from proof of concept toward prototype development and integration into semiconductor manufacturing environments.

HallTech is developing a new thin-film deposition platform designed to overcome limitations of conventional PVD technologies. Its approach uses a gridless ion-beam system to control the energy with which material reaches the substrate, enabling thin films to be deposited at high quality and throughput while operating at lower temperatures. The platform is intended to provide tighter control over film properties and material structures while reducing the trade-offs between deposition rate, quality, and energy consumption.

HallTech focuses primarily on semiconductor manufacturing, where increasingly complex material stacks and advanced device architectures are placing greater demands on thin-film deposition. Its technology is being developed for applications including next-generation semiconductor devices and advanced packaging, with potential applications extending into energy technologies such as solid-state batteries and perovskite photovoltaics. The company's broader objective is to enable functional coatings and material structures that are difficult or inefficient to produce using conventional deposition methods.

HallTech combines plasma physics, Hall-effect plasma technology, ion-beam physics, thin-film deposition, materials science, vacuum engineering, and process development. Its core platform adapts the Hall-effect thruster concept, traditionally used for spacecraft propulsion, to generate and control plasma for PVD rather than propulsion. The company is developing gridless ion-beam technology together with process control and materials expertise to precisely tune ion energy and the resulting film properties. Its technical development also involves simulation, metrology, mechanical and electrical system engineering, and semiconductor-fab integration.

HallTech is addressing a fundamental bottleneck in advanced manufacturing: depositing increasingly demanding material stacks without sacrificing throughput, film quality, temperature compatibility, or energy efficiency. Its technology has potential applications in next-generation semiconductor devices and advanced packaging, while its underlying deposition approach can also support advanced energy materials. HallTech has already partnered with the University of Southampton to develop and test its first proof-of-concept ion source, and with Universidad Carlos III de Madrid to validate the underlying physics and simulation models for its PVD technology.

The company is now transitioning from technology validation toward hardware development and industrialization, including scaling its platform toward 12-inch wafer processing and eventual fab integration. This development requires expertise spanning plasma generation, source engineering, materials, process engineering, metrology, and semiconductor equipment integration.

HallTech partners with Metheion to source highly specialized engineering and R&D profiles across plasma physics, ion sources, thin-film deposition, materials science, vacuum technology, semiconductor equipment, process engineering, and system development.

Metheion specializes in identifying engineers and scientists with the combination of theoretical expertise and hands-on experience required to develop complex deep-tech hardware. Through this partnership, Metheion supports HallTech as it moves from laboratory-scale technology toward industrial hardware by connecting the company with specialized technical talent capable of developing plasma sources, deposition processes, equipment architectures, materials, and the engineering systems required for semiconductor-fab integration.
