Smoltek Semi AB is pio­neer­ing ultra-thin car­bon nanofiber-based met­al-insu­la­tor-met­al (CNF-MIM) capac­i­tor tech­nol­o­gy. To accel­er­ate our tech­nol­o­gy plat­form towards robust, high-yield prod­ucts, we are look­ing for a hands-on Reli­a­bil­i­ty & Char­ac­ter­i­za­tion Engi­neer to take own­er­ship of the elec­tri­cal char­ac­ter­i­za­tion and reli­a­bil­i­ty assess­ment of our ALD-based dielec­tric stacks and CNF-MIM capacitors.

This is a lab-cen­tric and data-dri­ven role where you will work close­ly with process, mate­ri­als, and device col­leagues to under­stand per­for­mance, iden­ti­fy fail­ure modes, and dri­ve design and process improvements.

You will direct­ly report to the CTO.

What you will do: 

• Own and devel­op the elec­tri­cal char­ac­ter­i­za­tion method­ol­o­gy for CNF-MIM capac­i­tors includ­ing:
  • C–V, I–V, break­down, and leak­age measurements 
  • Fre­quen­cy-depen­dent char­ac­ter­i­za­tion and loss measurements 
  • Tem­per­a­ture-depen­dent characterization 
• Design and exe­cute reli­a­bil­i­ty test plans for CNF-MIM capac­i­tors and dielec­tric stacks, includ­ing:
  • Time-depen­dent dielec­tric break­down (TDDB)
  • Endurance and cycling tests and reten­tion measurements 
  • High-tem­per­a­ture stor­age /​ HTOL-like tests and ther­mal cycling 
  • Eval­u­a­tion of sta­bil­i­ty vs. bias, tem­per­a­ture, and environment
• Ana­lyze mea­sure­ment and reli­a­bil­i­ty data using appro­pri­ate sta­tis­ti­cal tools: 
  • Weibull analy­sis, con­fi­dence inter­vals, and life­time extrapolation 
  • Cor­re­la­tion of reli­a­bil­i­ty met­rics with process and struc­tur­al parameters 
  • Clear visu­al­iza­tion and com­mu­ni­ca­tion of trends, out­liers, and fail­ure mechanisms
• Con­tribute to the set­up, main­te­nance, and con­tin­u­ous improve­ment of: 
  • Elec­tri­cal test bench­es (para­me­ter ana­lyz­ers, LCR meters, probers, etc.) 
  • Auto­mat­ed test scripts and data pipelines (e.g. Python) 
  • Inter­nal reli­a­bil­i­ty test stan­dards and documentation
• Con­tribute to devel­op­ment of 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.
• 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 Elec­tri­cal Engi­neer­ing, Sol­id State Physics, Mate­ri­als Sci­ence, or similar.
• Strong hands-on expe­ri­ence in elec­tri­cal char­ac­ter­i­za­tion of capac­i­tors or relat­ed devices (MIM, MOS, DRAM, var­ac­tors, etc.).
• Prac­ti­cal expe­ri­ence with reli­a­bil­i­ty test­ing of dielec­tric stacks and/​or capac­i­tors, for exam­ple TDDB, BTI, stress tests, HTOL, cycling, or similar.
• Proven abil­i­ty to ana­lyze reli­a­bil­i­ty data and build/​interpret life­time mod­els (e.g. Weibull)
• Good under­stand­ing of High‑k dielectrics and met­al-insu­la­tor-met­al (MIM) or met­al-oxide-semi­con­duc­tor (MOS) structures
• Expe­ri­ence with ALD for high‑k dielectrics or barrier/​seed/​electrode layers
• Com­fort­able work­ing with semi­con­duc­tor test equip­ment (para­me­ter ana­lyz­ers, SMUs, LCR meters, probers)
• Basic project man­age­ment skills – abil­i­ty to define tasks, plan mea­sure­ment and reli­a­bil­i­ty cam­paigns, and com­mu­ni­cate sta­tus, risks, and conclusions.
• A struc­tured way of work­ing, with atten­tion to detail, repro­ducibil­i­ty, and trace­abil­i­ty of data and results.

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.
