PolarTip · high aspect ratio SiC AFM probes.
Explore the product line and pilot opportunities.

Scientific instruments for understanding the nanoscale.

Tiny Infinities develops measurement tools for semiconductor development and scientific research. Our expertise combines advanced silicon carbide nanofabrication with Raman polaritonics—an approach to sensing the infrared optical properties of nearby materials using visible light.

OUR FIRST PRODUCT / POLARTIP

SiC AFM probes for demanding surfaces.

PolarTip is our silicon carbide probe line for atomic force microscopy. It brings our fabrication expertise to the challenges of feature access, tip wear and faster scanning.

01

Access fine, narrow features

A sharp apex and high aspect ratio address the challenge of reaching narrow surface features. Match the tip profile to the details you need to measure.

02

Preserve useful tip geometry

Tip wear can change apparent feature dimensions. PolarTip is designed around wear resistance to support consistent measurements over repeated scans.

03

Advance high-speed AFM

PolarTip probes are being developed for faster scanning and sustained surface measurements, combining SiC’s stiffness with resistance to wear and breakage.

Work with us on a PolarTip pilot, with specifications and geometry shaped around your AFM setup and measurement needs.

APPLICATIONS

Understand surfaces through each process step.

Semiconductor and thin-film development

Compare surface topography, roughness and patterned features before and after a process step. Probe selection starts with the surface changes you need to understand.

AFM research and shared facilities

Repeated scans and shared instruments place demands on tip condition. Define a pilot around usable data, replacement frequency and the needs of your facility.

Instrument development

Develop probe configurations around your cantilever, readout and integration requirements, including collaborations on faster AFM scanning.

THE CAPABILITY BEHIND THE PRODUCT

Advanced nanofabrication in silicon carbide.

Silicon carbide is hard and chemically resistant, making it valuable for demanding applications and challenging to shape precisely. We fabricate advanced nanoscale structures in SiC and develop them into measurement tools.

PolarTip is our first product built on this expertise. We also welcome selected collaborations on SiC structures for measurement and sensing.

POLARSENSE / ACTIVE EXPLORATION

New ways to measure thin films.

Alongside PolarTip, we are exploring Raman polaritonics for thin-film measurement. This work underpins PolarSense, a future product direction for optical sensing shaped with semiconductor teams and research partners around their materials and measurement questions.

Engineered SiC nanostructures provide the sensing element. Visible-light Raman readout reveals how their response changes with the material nearby.

THE TEAM / GOTHENBURG

Research and engineering, brought together.

Based in Gothenburg, our team combines nanophotonics, nanofabrication, engineering and commercial development. Our work grew from research and entrepreneurship at Chalmers.
