Finnish 3D thin film semiconductor metrology specialist launches new PillarHall LHAR5 test chip with 100 nanometer gap height, complements its metrology solution with new ASD-1 chip for Area Selective Deposition.
Joensuu, Finland – July 15th, 2024 – Chipmetrics Oy, an innovative metrology solutions provider to the semiconductor industry, announces the launch of two new test chips, the PillarHall LHAR5 and the ASD-1. The PillarHall LHAR5 silicon test chip builds on the success of its predecessor PillarHall LHAR4, with the new LHAR5 test chips being better suited for the most advanced 3D semiconductor device high aspect ratio structures with a gap height as low as 100 nm. Fitting seamlessly into Chipmetrics’ pocket wafer concept, it also allows for fast and accurate process control with full 300-millimeter compatibility.
The PillarHall LHAR5 test chip comes in two variations, with a 100-nanometer and a 500-nanometer gap height. The new 100-nanometer gap height allows engineers to research and compare possible dimensional effects in film penetration depth in line with 500-nanometer gap chips. This allows for new insights into film conformality control and a deeper understanding of 3D NAND, DRAM and other nanoelectronics containing high aspect ratio structures.
“With the launch of PillarHall LHAR5, ASD-1 and the 300-millimeter pocket wafer concept our product line is compatible with the most advanced and challenging semiconductor deposition and etch technologies like ALD, ALE and ASD. The Chipmetrics test chips with our pocket wafer concept is directly compatible with and ready to be used in all existing deposition tools,” says Mikko Utriainen, CEO of Chipmetrics.
The Chipmetrics ASD-1: Prototyping and Process Control for Area Selective Deposition workflows
Launched concurrently with the PillarHall LHAR5 is the Chipmetrics ASD-1 test chip, for prototyping and process control of Area Selective Deposition (ASD) workflows. As the name implies, ASD allows for selective growth of thin films on specific substrate areas, while avoiding it on others, with the ASD-1 test chip aiming to give customers easy access to high-quality data for process control and R&D.
The ASD-1 test chip features a high surface planarity, low line edge roughness, and small line widths which are crucial for ASD applications in advanced semiconductor manufacturing. The ASD-1 test chip features arrays of sub-100 nanometer narrow line structures with alternating materials aligned on the planar silicon substrate for accurately characterizing self-aligned area selective depositions through either Atomic Layer Deposition (ALD) or Chemical Vapor Deposition (CVD) and related processes. The Chipmetrics ASD-1 helps engineers to accelerate ASD process development to meet challenges in miniaturizing and scaling, as well as in reducing defects and improving yield.
Both the PillarHall LHAR5 and ASD-1 test chips are available immediately. For more information on the products, please visit Chipmetrics.com.

Editor’s note on ALD:
Atomic Layer Deposition (ALD) is a precision thin-film deposition technique crucial for semiconductor manufacturing, enabling the production of uniform and conformal layers essential for microelectronic devices. Through alternating exposure to precursor gases that react with the substrate in a self-limiting manner, ALD achieves atomic-level control over film thickness and composition. This method ensures exceptional uniformity across complex geometries, vital for the miniaturized, multi-layered structures such as the future’s 3D chips in advanced semiconductor devices, keeping Moore’s Law alive.
Finland plays a key role in the ALD landscape, having pioneered the process in the 1970s. Finland’s contribution to ALD includes significant advancements in materials science, equipment design, and the exploration of new applications ranging from electronics to renewable energy sectors. The country’s strong emphasis on research and development in nanotechnology has positioned it as a hub for ALD innovation, fostering collaborations between academia, industry, and research organizations worldwide.
Chipmetrics Oy, based in Finland, has launched two new test chips: the PillarHall LHAR5 and ASD-1. The LHAR5 chip is made for advanced 3D semiconductor devices. It has very thin gaps that make processes faster and more accurate. It fits well with Chipmetrics’ pocket wafer method and works with large 300-millimeter wafers. This is a big step forward in semiconductor technology! As a computer science student, this information is very important to me because I am preparing a project related to it. Due to this project, I couldn't attend my online CS class. However, when I contacted the online class site and requested them to Do My Computer Science Class, it benefited me greatly.
ReplyDeleteThis is such an eye-opening article of such a robust Finland company introducing the cutting-edge technology, playing a pivotal role in the ALD landscape. Finland is already dominating its crucial presence in the educational landscape leading and now leading in this segment of material sciences flabbergast me and my fascination with this this topic and technology elevated to new level when I was seeking Business environment assignment help and expert assignment researcher selected this topic and redirected me to this article, one of the finest I have ever come across.
