The Lithuanian Factory That Wants to Save the Semiconductor Industry (and Lower Prices)
The skyrocketing prices of electronic components in recent months have a well-known cause, the rush for artificial intelligence, but also a less discussed consequence: the pressure on precision tools necessary to produce next-generation chips. It is in this context that the announcement of the Lithuanian startup LITILIT comes into play, which has recently begun work on a new femtosecond laser factory in Vilnius.
The issue of rising prices came back to prominence at the end of June when Apple announced a price increase of up to 30% on MacBook and iPad, citing a spike in component costs the likes of which had never been seen before in terms of speed and intensity. Apple's move was echoed by other producers, including Microsoft, Sony, Dell, and HP, who announced similar price hikes or are considering them.
According to Nikolajus Gavrillinas, co-founder and CEO of LITILIT, the phenomenon particularly affects memory chips, which have reportedly increased in price by about six times over the span of a year, driven by demand linked to data centers and artificial intelligence systems, according to an analysis by Morgan Stanley cited by Reuters.
However, LITILIT argues that the solution to the chip shortage does not only lie in expanding the production capacity of foundries, but also in the availability of precision tools necessary to create them. This is where femtosecond lasers come into play, a technology increasingly used in the production of advanced semiconductors due to its ability to perform extremely accurate processes with minimal thermal impact.
Gavrillinas explains that in the most modern production processes, even sub-microscopic thermal damage can render a component unusable. That is why manufacturers are turning to femtosecond lasers, capable of removing material without generating residual heat in the surrounding structures. However, Gavrillinas points out an additional risk: since this laser technology is also used in the production of data center equipment and numerous other advanced applications, its production, currently concentrated in a few facilities around the world, could itself become a bottleneck.
The issue is particularly relevant for Europe, which has recently proposed a second Chips Act with the aim of increasing its share of the global semiconductor market from 10% to 20% by 2030. The United States and China are also pushing to strengthen chip production on their territories, making the availability of precision tools like femtosecond lasers a strategic global issue.
To address this growing demand, LITILIT has started construction of a new facility in Vilnius, aiming to achieve a production capacity of 3,000 lasers per year within a couple of years of starting operations: a volume that, according to the company, would make it the largest facility in the world dedicated to this technology.
The lasers produced by LITILIT are based on several patents developed by the company's co-founders, Kęstutis Regelskis, Nerijus Rusteika, and Gavrillinas himself, in collaboration with the Center for Physical Sciences and Technology (FTMC) in Vilnius. The declared goal is to bring femtosecond lasers to a level of dissemination, ease of integration, and reliability comparable to that of nanosecond fiber lasers, which are currently much more widespread industrially.
Gavrillinas emphasizes how traditional femtosecond lasers, while offering high performance, are notoriously complex to produce and require highly specialized personnel. LITILIT claims to have developed a technology with lower component complexity, a design tailored specifically for mass production, and a high level of automation in production processes, characteristics that would make its lasers more suitable for large-scale production for high-precision applications, including semiconductor manufacturing.
According to the CEO of LITILIT, the lesson to be learned from the current chip crisis is that advanced manufacturing depends not only on the capability of lithographic processes but also requires access to an entire ecosystem of enabling tools, from femtosecond lasers to advanced packaging systems, to precision material processing technologies.
