Resist CSAR 62 is meanwhile established worldwide, with continuously increasing demands. Since we manufacture the polymer by ourselves, we had to scale up polymer synthesis. First of all, CSAR 62 made the jump from laboratory scale to a 20-liter trailer.
We continued the development work on our new Atlas 46 photoresist also in 2021. Due to own results or recommendations and requests from our users, its formulation and properties were now improved.
In 2004, the first bottom resist (BR) was developed in collaboration with the Center for Intelligent Systems (CiS, Erfurt). This bottom resist is non-light sensitive and can be developed in an aqueous alkaline manner.
The novel corona virus (COVID-19) is spreading rapidly across national borders. So far, the operational processes of Allresist GmbH have hardly been affected. We strive to meet our customers’ requirements as best we can in this tense situation and to minimize the impact on our operational processes as much as possible. The focus is on protecting our colleagues and our customers.
Optically dense resists play an increasingly important role in industry. So-called black resists are required in optical industry, in automotive industry (for headlights) and in the manufacture of rotary encoders.
Medusa 82 UV was already chosen as resist of the month in January 2019. Back then, we highly appreciated the first results for a use as photoresist. Shown are now results with respect to an application in grayscale lithography which were also presented at the MNE 2019 in Greece.
1. 27 years of Allresist – firmly established on the world market
2. Allresist successful on the congresses Triple Beam (EIPBN 2019) and MNE 2019
3. Medusa 82 for e-beam graytone lithography
4. Resist structures for the spin Hall effect
Just as in the previous years, Allresist was represented at the MNE congress with a prestigious booth. This year’s MNE was guided by the motto “Going Nano in Homer’s Land” – an excellent connecting point for our presentation since our new e-beam resist is named Medusa 82.
On April 29, 2019, Allresist put the new production wing into operation in which from now on 1,000 l resist batch productions and large-scale syntheses will take place with state-of-the-art technology and taking into account all safety considerations.
Allresist developed Phoenix 81 (AR-P 8100) within the scope of a Eurostars project together with SwissLitho AG and other partners. SwissLitho recently added a laser direct writer to the NanoFrazor device (see Fig. 1)
