Jolt Capital invests €20M in Tempress and Tempress to acquire SPT Microtechnologies USA as double consolidation play in high-end semiconductor equipment
VAASSEN, NETHERLANDS, July 16, 2026 /EINPresswire.com/ -- Jolt Capital invests €20M in Tempress and Tempress to acquire SPT Microtechnologies USA as double consolidation play in high-end semiconductor equipmentScaling European champions in semiconductors
Jolt Capital, the leading private equity firm specializing in growth investments in European deeptech companies, is committing €20 million to Tempress, a global player in thermal diffusion and deposition furnaces for high-growth “more-than-Moore” (MtM) semiconductor segments (Power, SiC, Photonics, MEMS).
Tempress’s vertical and horizontal furnace solutions are based on precise high-temperature diffusion and chemical vapor deposition (CVD) complex processes, supporting critical steps in material modification (semiconductor doping or functional coatings). Leveraging a solid legacy patents base, the technology can achieve uniform, high-quality material layers at industrial scale. Based in Vaassen (NL) and with a wide international footprint, Tempress sells its machines to global semiconductor fabs and to major R&D centers.
Jolt Capital joins a group of shareholders including Innovation Industries, a very experienced Netherlands-based deeptech and impact venture capital investor. Together they will build another strong and mature European player in the semiconductor equipment market, with already almost 60 years of market presence.
Marie Nicod, General Partner at Jolt Capital, said: "This first investment in Jolt Capital V is really a textbook example for us. A leading deeptech scaleup ready to be grown into a truly global platform by systematic M&A consolidations, with a first accretive move already activated. A clear value creation path that will hinge on our deep expertise in the field of semiconductor investment. And a company that exemplifies excellence in European industry and complex engineering."
Tempress to acquire SPT Microtechnologies USA
Capitalizing on Jolt Capital’s investment and support, Tempress has concurrently signed an agreement to acquire San Jose (CA) based SPT Microtechnologies USA, Inc., a wholly owned subsidiary of SPP Technologies Co., Ltd. This specialist in vertical furnaces for complex MtM thermal processing offers very complementary assets to Tempress, in terms of product lines, geographical coverage, and inroad to additional key customers.
The acquisition of SPT-USA, including its subsidiaries in Germany and Taiwan, strengthens Tempress’ position in the semiconductor equipment market by combining non-rival product portfolios, engineering expertise, and customer relationships. The combined group will be well positioned to support customers across a broad range of applications, while accelerating innovation and service capabilities globally.
Tempress intends to integrate SPT-USA into its organization, maintaining operational continuity while unlocking synergies in technology development, manufacturing efficiency, and global service support.
Pieter de Groot, CEO of Tempress, comments: “This funding round and the acquisition represent a dual major step forward in our ambition to build a leading semiconductor equipment platform. By combining SPT-USA’s capabilities with Tempress, we strengthen our technology and product offering, expand our global installed base, and enhance our ability to support customers worldwide. Jolt Capital’s track record in funding semicon and capital equipment is truly impressive, that’s why we are so pleased to partner with them to further accelerate this next phase of growth.”
