MPD is a thick-film micro fabrication process that uses a polymeric stamp to transfer ink onto a substrate.
MPD is a thick-film micro fabrication process that uses a polymeric stamp to transfer ink onto a substrate.
The stamp allows to deposit nano and micro-materials at wafer-scale (4" - 8") with extensive parallelization.
The stamp contains microchannels which are filled with micro and nano- materials. This results in accurate deposition of full 3D-controlled microstructures.
By accurately fabricating the stamp, a highly reproducible deposition process is achieved.
MPD requires three components: a substrate, a stamp and an ink. Through six process steps an in-house developed tool cycles through the MPD process, shown below:
See our printing materialsThe substrate is loaded by an automated wafer handling system onto a wafer chuck in the tool.

The stamp is aligned and accurately placed by the tool on the substrate. The stamp and substrate are in direct contact and seal through adhesive forces.
The ink (printing material) is injected from the top into the stamp and flows through a network of channels into the microchannels that are contained in the stamp and get filled.
Once the microchannels are completely filled, the ink is cured by removing the solvent while the stamp is still in contact with the substrate. Thereby, the printed structures become solidified.
Once the ink is cured, the stamp is gently peeled-off by the tool to make sure the printed features remain freestanding on the substrate.
Once the stamp is removed, the substrate is sintered at elevated temperature, to remove any binders/polymers and to give the printed material its desired properties (e.g. conductivity, porosity).
The stamp needs to adhere to the substrate for proper printing conditions. It is possible to print on rough surfaces as long as the roughness (Ra) is below 2 microns.
The stamp is in-house fabricated by Mesoline and made from a polymer. Thereby it is flexible and can adhere to the substrate to properly seal which is required for the MPD process.
The stamps are single-use, but recyclable.
Yes, we can print with up to four materials simultaneously. In other words, in one process step we put down stamp and can inject 4 different materials on the wafer/substrate.
This depends on the requirements of the material and possible substrate constraints. Typically the wafers are sintered between 250 - 500°C.
The stamp is uniquely designed and fabricated in-house depending on customer design. Mesoline has developed tooling and production lines to produce these stamps at scale.
We can handle substrates from 100 (4-inch) typically used in R&D, up to 200 mm (8-inch) substrates.
The key in the fact that we cure the ink while that stamp is still in contact with the wafer. So we first build-up the high-aspect ratio volume with ink, subsequently we cure the ink and remove that stamp. The highest aspect-ratio we have achieved is 1:5.
Mesoline got invited to give a talk at the MEMS & Imaging Sensors summit in Grenoble, France from September 19 – 21, 2023. The summit will bring together leaders and industry experts to discuss the latest MEMS and imaging technologies and how they can significantly impact future product developments and applications.
It’s been a year since Thomas Russell, CEO Mesoline, presented at MSTC (MEMS and Sensors Technical Conference) 2022 in Berkely, US. The talk was recorded by Semi and can be viewed on youtube: https://www.youtube.com/watch?v=fhSYGNrkn8M&feature=youtu.be&ab_channel=SEMIMEMS%26SensorsIndustryGroup In this presentation Thomas explains the microchannel particle deposition process and its unique features/advantages. This year, Mesoline will again be present at the MSTC at MIT in Boston, 2023.
Mesoline was selected by the municipality of Rotterdam as one of the leading innovative companies in the Rotterdam. For that reason, the mayor of Rotterdam, Ahmed Aboutaleb visited Mesoline in person. Marnix Rebergen (CTO) and Thomas Russell(CEO) showed Mr. Aboutaleb around at Mesoline and explained why Rotterdam has such an great environment for technology companies to scale!
Mr. Aboutaleb has a background in electrical engineering and showed deep interest in the latest activities of Mesoline.
On September 6 – 8, 2023 Mesoline will go to Semicon Taiwan, in Taipei. In addition, we will be attending the MEMS & Sensor Forum on Tuesday September 5th. This is the most important event for the micro- and nano-electronics industry in Taiwan. We would love to meet up and discuss opportunities for fabricating next generation MEMS and sensors using Mesoline's micro-channel particle deposition (MPD) technology.
On June 13-14, in Porto, Portugal - The MEMS World Summit EU 2023 was hosted at the Amkor Technology ATEP site. Leaders from the MEMS & Sensors Manufacturing Ecosystem gathered over 2 days to share ideas and collaborate on initiatives in our trusted network. Thomas Russell, CEO and Co-Founder of Mesoline presented on About Mesoline’s Emerging 3D Micro Printing Technology, Micro channel Particle Deposition (MPD), used for MEMS & Sensors.
Mr. Wim Pelsma (CEO Aalberts N.V.) and Joey Hunsel (M&A Director) visit Mesoline B.V. headquarters in Rotterdam, NL. The team hands over the first MPD printed wafer to Mr. Pelsma and thank him for his support throughout the years. In 2023, Mr. Pelsma stepped down as CEO of Aalberts N.V. after 12 years. Aalberts N.V. acquired Mesoline B.V. through 100%acquisition in 2021.
We are showcasing our solutions at SENSOR+TEST in Nürnberg, Germany on May 9-11. Can't wait to see you on our stand. Meet us in Hall 2 at stand 102. Mesoline visited the largest trade show on Sensors in Europe: Sensor + Test. Mesoline has it own booth in Hall 2, stand 102.
