Research infrastructure NanoLab is an open-access infrastructure, providing facilities in nano materials characterization located at the Department of Physics.
We are an open-access infrastructure located at the Department of Physics, which means anyone can use our equipment after having an adequate training. NanoLab provides the possibility to:
Besides, NanoLab is a classified Class 100 cleanroom that can be used for your own experiments.
The Nanolab was established in June 2012, and has since its inception been in continuous development. Today, it comprises a variety of advanced fabrication and characterization setups, including a mask aligner (Karl Süss Mask Aligner MJB3), a nanoimprinter (Obducat NIL 2.5), a thin-film deposition system (PVD75 thermal evaporator), X-ray diffractometer (PANalytical Xpert3 Powder), a contact angle meter, and a spin coater, as well as number of more standard pieces of equipment, such as vacuum ovens, hotplates, optical microscopes, UV-curing boxes, and analytical scales. A short overview of the available equipment can be found below:
As NanoLab's environment is extremely clean (10 000 times less airborne particles than in a normal laboratory), it is possible to manufacture and study materials with notably high standard and precision. The facility is currently an invaluable tool for the University´s rapidly expanding research in the fields of microelectronics, optics and photonics, and nanotechnology, but it is also of obvious interest for scientists that are interested in, e.g., the fabrication and/or appropriate characterization of thin films, or materials that feature structures on the micrometer or sub-micrometer level. As such, its potential users encompass experimental researcher in essentially a wide variety of fields in natural science and medicine.
Director of the NanoLab (Dr.rer.nat. Roushdey Salh), Department of Physics.
The equipment in NanoLab is made available to all scientists at Umeå University, as well as external institutions, for a fee of 300 SEK per hour. It is possible for high-volume users to apply for a discount. The NanoLab manager offers training sessions on each piece of equipment on an annual basis or on demand, and after approval following the training the user can independently use the equipment he or she has been trained on. Non-approved users can only use a piece of equipment under the supervision of the manager. Manuals and handbooks have been developed for each piece of equipment, and are available online or beside the equipment.
All of the equipment in NanoLab is available for booking during normal work days, and the booking system is available at:
www.phys.umu.se/cleanroombooking
Training and special courses concerning the equipment are offered annually often in November or December (exact date announced under KBC research courses), but also possible on demand.
NanoLab is used for both undergraduate education (grundutbildning) and graduate teaching. Two advanced courses on the undergraduate level (Nano Science 7.5hp and Advanced Materials 7.5hp) currently use NanoLab as their laboratory facility in which the experiments are carried out. Two courses on the graduate level (Cleanroom technology 1.5 ECTS and Physical thin film deposition 1.5 ECTS) are also offered annually and are announced at the KBC website. These courses have primarily attracted participants from the Physics, Chemistry and Applied Physics department, but participants from the international business program and the department of Clinical Microbiology have also attended. Specific teaching and training sessions have also been offered on a regular basis to interested users. The courses are given in English, and the numbers of students are between 17 and 25 in each undergraduate course, and between 5 and 10 in each graduate course. For the coming years, courses are planned in Nano-imprinting and Material surface modification.

Filmetrics F10-RT-UVX
Thin film measurements system based on spectral reflectance (SR), is a non-contact technique that requires no sample preparation to measure film thickness. Light that is reflected from the film is analyzed in about one second to determine both a film’s thickness and refractive index. Multiple-layer films can also be measured.
Suitable mostly for transparent films, enabling measurements of films 30 Å to 100 μm thick films. The Filmetrics system Model F10-RT-UVX measures even translucent thin films made from virtually all common materials (metals) up to 200 nm. Typical accuracy is within a few angstroms.
