Editor’s Note
This article discusses a significant industrial investment in Trujillo, Spain, by Diamond Foundry, a company with ties to actor and investor Leonardo DiCaprio. While the project promises substantial job creation and technological innovation, the sourcing and verification of specific financial figures (e.g., the 2.35-billion-euro investment) remain pending final confirmation from official corporate or governmental channels. Readers are advised to treat this particular figure as preliminary.
Trujillo (Cáceres) has been on everyone’s lips since November 2025 due to news that looks like a turning point. Diamond Foundry, a company in which Leonardo DiCaprio participates as an investor, will build a factory there for high-performance chip components.
The plant will be one of the first in the world dedicated to producing diamond substrates for semiconductors. The planned investment amounts to 2.35 billion euros until 2029, which is certainly not small change. The project will bring hundreds of direct and indirect jobs and technical specialization to the area. And, if everything goes as expected, it could put Spain on the map for next-generation semiconductors.
The project consists of building a factory in Trujillo (Cáceres, Extremadura) to produce high-performance chip components using cutting-edge technology: synthetic monocrystalline diamonds used as a semiconductor substrate, i.e., the base on which the chip is built.
The facility adds to the activity that Diamond Foundry already had in the area and will not only increase ingot production. It will also incorporate key processes such as wafer cutting, lapping, polishing, and quality inspection. Yes, we are talking about diamonds; but not for rings.
According to official data, the plant will generate around 500 highly qualified direct jobs and about 1,600 indirect jobs linked to auxiliary services, supply chain, logistics, maintenance, and inspection. Overall, the project could exceed 2,100 positions, a significant figure for the local labor market.
The types of jobs in demand will be varied: specialized technicians for semiconductor production, engineers, factory operators (cutting, lapping, polishing, inspection), as well as profiles in logistics, maintenance, administrative management, and auxiliary services. This opens a notable opportunity for young people, graduates, technical personnel, and also for those seeking employment in auxiliary sectors.
Trujillo was chosen because a synthetic diamond plant already existed there. This provides an industrial base, local experience, and prior knowledge of synthetic diamond manufacturing that reduces uncertainties and accelerates the start-up.
Furthermore, the project aligns with the idea of decentralizing the technology industry in Spain, reindustrializing and revitalizing areas marked by depopulation and lack of opportunities. It also fits the objective of controlling manufacturing and production to reduce costs, a frequent Achilles’ heel in the national industry.
The exact details of the selection process have not been publicly released. It is expected that, once the plant is operational, the offers will be disseminated directly from Diamond Foundry or through job portals linked to SETT or the regional government. The key here will be to pay attention to those channels, without going through the umpteenth window.
Profiles with different levels of education and experience will have a place: from university graduates to operators, technical or administrative personnel. Consequently, there will also be opportunities for logistics, maintenance, and inspection, as well as for auxiliary services linked to the supply chain.
This is not Diamond Foundry’s first project in Trujillo: the company already had a factory dedicated to industrial-grade synthetic diamonds, aimed at uses such as jewelry. If it materializes as announced, the new plant will not only transform the local economy but could position Spain as a benchmark in next-generation semiconductors.
