Semiconductor designer and manufacturer Inpria recently secured $31 million in Series C funding. The company’s latest investment round included contributions from Intel, Samsung, and SK hynix.

The 13-year-old firm has captured the interest of the component industry because of its innovative extreme ultraviolet lithography (EUV) photoresists.

Inpria’s Groundbreaking EUV Work

Based in Corvallis, Oregon, Inpria specializes in developing EUV photoresists. The company began its life in 2007 after it spun off from the University of Oregon. Today, the firm fabricates its products using tin-oxide nanoclusters that are considerably smaller than the materials used in polymer-based resists.

The manufacturer’s unique design process allows it to produce a material with much greater resolution and EUV photon absorption than other traditional components. Inpria’s innovative photoresists provide semiconductor manufacturers with etch selectivity, which simplifies the production process and permits larger fabrication windows.

In recent years, component manufacturers have looked to EUV lithography as a way to produce the next-generation chips affordably and quickly. Original equipment manufacturers (OEMs) want components with increasingly small footprints so they can make sleek electronics that don’t skimp on functionality. EUV provides a way forward as it promises a 20 percent reduction in processing time and a 25 percent increase in output at scale.

Last December, The Burn-In reported on Samsung’s decision to dedicate $116 billion to increase its EUV manufacturing capacity. The corporation launched the project in hopes of dominating the lucrative custom enterprise processor sector.

The leaders of the semiconductor industry have poured money into Inpria due to the quality and utility of its photoresists. The startup’s products allow component makers to optimize EUV chip fabrication. Plus, the firm produces manufacturing material at different levels of industry specified resolution, sensitivity, and linewidth roughness. As such, corporations can easily integrate the company’s resists into their existing semiconductor workflows

Inpria’s Future Plans

Since its founding, Inpria has secured $67.8 million in outside capital. The firm’s investors include JSF Micro, Applied Materials, and TSMC, as well as the aforementioned Samsung and Intel. As the startup stands at the precipice of a revolution in semiconductor manufacturing, its future is very bright. In fact, the company recently launched a new high-volume production facility to meet demand.

Inpria will use its latest cash injection to scale up its operations further and continue its research and development efforts.

Company CEO Andrew Grenville offered a positive outlook in light of his startup’s recent success and long-term prospects.

“We are delighted that our investor base now includes all semiconductor manufacturers worldwide that are currently adopting EUV patterning. This achievement is complemented by the strong participation of photoresist, equipment, and industrial chemical manufacturer investors as well,” said the executive. “We look forward to working with our global partners to deliver a breakthrough EUV photoresist platform to the industry.”

Since its inception, the technology industry has always strived to find ways to supplant existing methodologies with new systems. Inpria and its game-changing photoresists exemplify that ethos.
