Resist für die Startseite (Resist des Monats)
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.
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.
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.
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.
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.
Fluorescent structures are needed for optical components and in microscopy. In close collaboration with Precision Optics Gera GmbH we now achieved to add fluorescent dyes to PMMA e-beam resists on anisole basis which subsequently could be structured by electron beam lithography.

Spray resist AR-N 2220 is the only ready-to-use negative resist worldwide. This eliminates the need for the time-consuming and inaccurate mixing of a resist with solvents.
T-gates are required for the manufacture of high-quality transistors. Allresist optimised several three-layer systems for this particular application and designed both universal developers for a single development step, as well as individual developers which are suitable to develop each one of the three layers specifically.
