April 2019: Phoenix 81

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)

Resist of the Month of October: Medusa 82 – alternative to HSQ

Allresist now developed Medusa 82 as an alternative to HSQ resists. Due to a modification of the polymer, resist Medusa 82 can be handled very easily.

Great success with Medusa 82 at the MNE

Once again Allresist participated in the MNE with a large, attractive booth and new innovations. As in past years, the interest of the conference participants in our diverse new developments was great. The absolute highlight however was the introduction of our Medusa 82, an excellent alternative to HSQ resists.

Resist of the Month July: Medusa 82 – the alternative to HSQ-resists

Our research team successfully developed a negative resist with high resolution and plasma etching stability in oxygen. Already with the first samples, it was possible to achieve the properties of HSQ.

Allresist at the EIPBN 2018 Conference in Puerto Rico

Allresist attended the “triple-beam” conference EIPBN 2018 for the first time. Matthias Schirmer and Dr. Christian Kaiser answered many inquiries at the exhibition stand, especially questions regarding electron beam resists.

Resist of the month of April: Fluorescent negative photoresist Atlas 46 S

These poly(phthalaldehydes) are also suitable for electron beam lithography and for the fabrication of 200 nm thick fibers (electrospinning). The material produced from these threads evaporates immediately upon heating, which offers interesting application possibilities.

Resist of the month January: SU 8 alternative – negative photoresist Atlas 46

The outstanding properties of SU-8 are well known to all users of microsystem technologies. Allresists new negative resist Atlas 46 S (solid) can easily be processed with high reproducibility of all properties and with high restistance of resist structures to all commonly used solvents. Atlas 46 S is thus perfectly suitable for all applications in which the layer is intended to remain permanently and resistively on the substrate.
