Smoltek Semi AB is pio­neer­ing ultra-thin car­bon nanofiber-based met­al-insu­la­tor-met­al (CNF-MIM) capac­i­tor tech­nol­o­gy. To accel­er­ate our tech­nol­o­gy devel­op­ment, we are look­ing for an expe­ri­enced and hands-on ALD Research Engi­neer who can devel­op, char­ac­ter­ize, and opti­mize dielec­tric stacks as well as met­al elec­trode lay­ers for inte­gra­tion on CNF-based struc­tures. The work will pri­mar­i­ly be per­formed using Smoltek’s in-house ALD tool.

This is a lab-cen­tric role where you will work close to process, mate­ri­als, and device col­leagues to push per­for­mance, yield, and manufacturability.

You will direct­ly report to the CTO.

What you will do: 

• Devel­op ALD dielec­tric stacks (e.g. Al₂O₃, HfO₂, ZrO₂, lam­i­nates) tai­lored for high-capac­i­tance CNF-MIM devices, with focus on con­for­mal­i­ty over 3D/​CNF struc­tures, low leak­age, and reliability.
• Engi­neer ALD/CVD/PVD-com­pat­i­ble met­al elec­trodes (e.g. TiN, Ru, W) suit­able for CNF-based MIM integration.
• Plan and exe­cute exper­i­men­tal series/​DOEs – define objec­tives, time­line, and deliv­er­ables, and fol­low up with clear report­ing to stakeholders.
• Coor­di­nate with adja­cent teams (CNF growth, device, reli­a­bil­i­ty) to align process require­ments, time plans, and tool availability.
• Char­ac­ter­ize films and stacks using ellip­som­e­try, XRD (with part­ners), SEM, TEM (with part­ners), AFM, and elec­tri­cal tests (C‑V, I‑V, breakdown).
• Doc­u­ment and trans­fer process­es into well-described run sheets and con­tribute to design rules for the CNF-MIM tech­nol­o­gy platform.
• Work with exter­nal labs/​foundries when need­ed for advanced char­ac­ter­i­za­tion or pilot production.
• Con­tribute to IP gen­er­a­tion through nov­el­ty in mate­ri­als stacks and inte­gra­tion schemes.

What you bring: 

• M.Sc. or Ph.D. in Mate­ri­als Sci­ence, Sol­id State Physics, Elec­tri­cal Engi­neer­ing, Chem­i­cal Engi­neer­ing, or similar.
• Hands-on expe­ri­ence with ALD (ther­mal and/​or PEALD) for high‑k dielectrics or barrier/​seed/​electrode layers.
• Good under­stand­ing of film growth on 3D or high-aspect-ratio struc­tures and the chal­lenges of con­for­mal­i­ty, nucle­ation, and sur­face preparation.
• Expe­ri­ence with at least some of the following: 
  • High‑k dielectrics for MIM/​MOS devices
  • Con­duc­tive nitrides (TiN, TaN) or Ru/​W electrodes
  • Leak­age, break­down and reli­a­bil­i­ty test­ing of dielec­tric stacks
  • Plas­ma sur­face treat­ments and adhe­sion promotion
• Basic project man­age­ment skills – abil­i­ty to define tasks, pri­or­i­tize exper­i­ments, keep sim­ple time plans, and com­mu­ni­cate progress/​risks.
• A struc­tured way of work­ing, with atten­tion to detail and reproducibility.

Nice to have:

• Knowl­edge of car­bon nano­ma­te­ri­als (CNT/​CNF/​graphene).
• Famil­iar­i­ty with semi­con­duc­tor process flows.
• Expe­ri­ence work­ing with exter­nal sup­pli­ers, foundries, or equip­ment vendors.
• Patent or pub­li­ca­tion track record in thin films or MIM devices.

Why Smoltek?

Smoltek is work­ing on a tech­nol­o­gy you won’t find just any­where; we com­bine car­bon nanofibers with advanced thin films to enable next-gen­er­a­tion capac­i­tors. Here you get to work close to the actu­al devices, see the impact of your exper­i­ments quick­ly, and dri­ve the process flow rather than just fol­low­ing it. The team is small, skilled, and col­lab­o­ra­tive, so good ideas move fast. And you get to do all of this in a bal­anced work–life environment.
