Cleanroom Engineer (m/f/d) (2024)

Scientist Hamburg

Solid State Research & Material Sciences

Job Offer from August 09, 2024

The Max Planck Society is Germany's premier research organization. The 84 Max Planck Institutes conduct research at highest levels, in the service of the general public, in the natural sciences, life sciences, social sciences, and the humanities.

The Max Planck Institute for the Structure and Dynamics of Matter (MPSD) is located at the Science Campus Hamburg-Bahrenfeld and investigates dynamical phenomena within matter down to the elementary timescales of atomic and electronic motions, the femtosecond or attosecond timescale. The focus is on the use of short wavelength ultrafast probes, such as X-rays or electron pulses, which are capable of measuring atomic and electronic structures in matter of all kinds.

The MPSD currently consists of three scientific departments focusing on solid state physics and theoretical methods in these fields. The MPSD is a partner in the Center for Free-Electron Laser Science (CFEL), collaborating with the Deutsches Elektronen Synchrotron (DESY), European XFEL (EuXFEL) and the University of Hamburg in the development of science based on the X-ray Free Electron Lasers (XFELs).

For our new department "Microstructured Quantum Matter" we are looking for a Cleanroom Engineer (m/f/d).

We are currently establishing a new micro- and nano-fabrication center for quantum materials at our Max-Planck-Institute for the Structure and Dynamics of Matter. Our scientific goals concern the device fabrication of non-standard materials into hybrid devices, which relies on clean-room processing. Wafer and chip processing will take place at the “Center for Hybrid Nanostructures” (CHyN), our scientific partner at the University of Hamburg and our next-door neighbor.

The position

The primary goal of this position is to support the common clean-room activities and coordinate the fabrication between the partners. Your role encompasses many diverse activities that balance well, including process development, machine maintenance, teaching and coordination.

Specifically, you will be in charge of operation and maintenance of two major pieces of equipment, a high-precision UV laser writer and a multi-source physical vapor deposition system (PVD). The systems must operate at their feasibility limit daily, which means robustly write 300nm features into standard resist or production of hom*ogenous thin films at high reproducibility. This will require continued attention and adjustment in weekly maintenance and alignment cycles. Maintaining cleanliness and minimizing process cross-contamination will be a key aspect of this work, as well as exchanging material sources to switch between different processes.

In this creative position, you will be actively engaging with the users of these machines and come into contact with wide areas of research, including biology, chemistry and physics; as well as industry partners. Your teaching roles will include continuous training of users to maintain best-practice operations in our facilities. You will be the contact points for students and postdocs who want to translate their research questions into real microstructures. This will be a stimulating and active environment, as the diverse research topics have broadly varying demands on the microstructures. Unlike industrial clean room processing, the R&D environment of a university clean-room exposes you to a stimulating environment of constantly evolving processes, projects and scientific questions.

Lastly, operating the clean room is a community effort. Part of this role is also to help out other users and technical staff in other clean-room related processes.

Your background and skills

We are looking for a highly motivated and dynamic person to work in a vibrant international environment with the aim to push the limits of state of the art nanofabrication. You should be interested in developing new processes and procedures in this evolving environment, and in general enjoy solving challenging puzzles.

Experience of clean room work is required (>2 years), either during an academic research project or in industry. A master degree either in a technical science or in chemistry/biology connected to microfabrication aspects is a prerequisite and a PhD in a related subject welcome. Experience with lithography and/or PVD is important.

This position offers many opportunities to interact with a broad and international team of scientists. Naturally, fluent English and German is necessary. The diverse nature of this role needs a structured and independent person able to balance these roles. Yet above all, you must bring excitement and enthusiasm about bringing structures and ideas to life in the nanoworld!

Our offer

We offer an innovative environment, which will give you the opportunity to develop your own ideas in a low temperature high magnetic field facility in combination with state of the art micro machining capabilities. We offer an attractive remuneration according to the German public pay scale (TVöD). The appointment is for two years with the possibility to be made permanent.

The Max Planck Society strives for gender equality and diversity. We welcome applications from all background.

The Max-Planck Society is committed to increasing the number of individuals with disabilities in its workforce and therefore encourages applications from such qualified individuals.

Your application

To apply please complete the online application form and attach you English CV and motivation letter as well as all relevant certificates latest 13th September, 2024.

Detailed information about the Max Planck Institute for the Structure and Dynamics of Matter can be found at our website.

We look forward to your application.

FAQs

What is cleanroom grade D? ›

Grade D Cleanroom

Grade D cleanrooms are designated for less critical stages in the manufacturing process. They are equivalent to ISO Class 8 cleanrooms, both at rest and in operation. The maximum permitted concentration of airborne particles in Grade D cleanrooms is 3,520,000 particles ≥ 0.5 µm per cubic meter.

What is a clean room level D? ›

Class D is another common clean class. Class D cleanroom is used for handling components after washing and plasma stripping. Class D is measured in the at-rest state only. It must have less than 3 500 000 particles ≥0.5 μm and less than 20 000 particles 5 μm.

What is cleanroom IQ? ›

IQ stands for Installation Qualification and is effectively a test plan which is designed to ensure that any cleanroom has the right equipment in place. This includes the heating, ventilation and air conditioning units, as well as any HEPA filters they use.

What is the minimum air change rate for a cleanroom? ›

Summary: Cleanroom air changes rates refers to how many times per hour the cleanroom air is passed thru the HEPA filtration . The more air changes per hour the cleaner the cleanroom. An ISO-8/class 100k cleanroom requires 20 air changes per hour. A cleaner ISO-7 /class 10k cleanroom requires 60 air changes per hour.

What is the grade A to D? ›

A+, A, A- indicates excellent performance. B+, B, B- indicates good performance. C+, C, C- indicates satisfactory performance. D+, D, D- indicates less than satisfactory performance.

What are the requirements for Grade D cleanroom gowning? ›

Grade D: Hair, beards and moustaches should be covered. A general protective suit and appropriately disinfected shoes or overshoes should be worn. Appropriate measures should be taken to avoid any ingress of contaminants from outside the clean area.

What are the grades of clean rooms? ›

Grade A is the cleanest and is used for sterile operations. Grade B: This grade provides a background environment to enable aseptic preparation and filling for some grade A zone items. Grade C: Grade C cleanrooms are used to perform less critical activities needed for the non-critical manufacturing stages.

Prohibited Items in Cleanrooms

Cardboard, unapproved paper, bubble wrap, Styrofoam, tissues, paper towels, unapproved tape. Personal electronics, including phones, headphones, and computers. Jewelry, such as earrings, necklaces, bracelets, watches. Wood products.

What is the highest clean room level? ›

The "cleanest" cleanroom in FS209E is referred to as Class 1; the "dirtiest" cleanroom is a class 100,000. ISO cleanroom classifications are rated according to how much particulate of specific sizes exist per cubic meter (see second chart). The "cleanest" cleanroom is a class 1 and the "dirtiest" a class 9.

Which is the best cleanroom in the world? ›

Situated in Stuttgart, Germany, the Fraunhofer Institute's ultra-clean room takes cleanliness to an extraordinary level. The air quality surpasses the ISO 1 standard, containing less than one particle per cubic meter.

What is the ISO for clean rooms? ›

The most common ISO clean room classes are ISO 7 and ISO 8. The Federal Standard 209 ( FS 209E ) equivalent for these ISO classes are Class 10,000 and Class 100 000. The old Federal Standard 209E ( FS 209E ) includes these clean room classes : Class 100,000; Class 10,000; Class 1,000; Class 100; Class 10; Class 1.

What is a GMP clean room? ›

What Is GMP For Cleanrooms? GMP (Good Manufacturing Practices) are used to regulate the manufacturing of sterile products. The criteria of GMP were created to reduce the risk of contamination within production processes, and to ensure drugs contain the ingredients and amounts claimed.

How do you calculate CFM for a clean room? ›

ACH in simple terms is the number of times the air volume of the entire room needs to be changed every hour (Air change hour), and the air volume of the room is measured in cubic feet. So computed CFM will be = Air volume (i.e. Room's volume) x ACH (in hours) / 60.

What is the leakage rate in a clean room? ›

Air leakage should be controlled at a rate of 1-2%. The rate of air filtration from outside can be controlled by adjusting the air pressure within. Positive air pressure will keep “dirty” air from adjoining spaces and prevent it from entering the cleanroom.

What is the air velocity limit in a clean room? ›

Because of the complexity and uniqueness of each cleanroom installation, the guidance air velocity range of 0.36 – 0.54 m/sec (71 -106 ft/min) can only be reliably established ≤15 cm ( 6 inches) from the filter face.

What is the difference between Grade C and Grade D clean rooms? ›

Grade C – A clean area for less critical stages in the manufacturing process. It's equivalent to ISO Class 7 at rest and ISO Class 8 in operation. Grade D – Another clean area for less critical stages in the manufacturing process. It's equivalent to ISO Class 8, both at rest and in operation.

What is grade D in ISO? ›

Grade D. For Grade D, the airborne particle classification is the equivalent of an ISO 8 cleanroom at rest. While in operation, the particle classification is not predefined; it will depend on the nature of the processes taking place inside the zone.
