# Characterization and Reliability Engineer

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 Char­ac­ter­i­za­tion and Reli­a­bil­i­ty Engi­neer to take own­er­ship of the elec­tri­cal char­ac­ter­i­za­tion and elec­tri­cal 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
- **Dri­ve com­pact mod­el­ing and cir­cuit-lev­el eval­u­a­tion of CNF-MIM capacitors:**
  
  - o Devel­op­ment or cal­i­bra­tion of simplified/​compact capac­i­tor mod­els based on mea­sured elec­tri­cal behavior
  - o Use of SPICE or equiv­a­lent cir­cuit sim­u­la­tion tools to pre­dict and mod­el the behav­ior of CNF-MIM capacitors
  - o Cor­re­la­tion of sim­u­la­tion results with mea­sured data to refine mod­els and sup­port device and stack optimization
- **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
- **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.).
- Expe­ri­ence in SPICE or equiv­a­lent cir­cuit modeling.
- Prac­ti­cal expe­ri­ence with reli­a­bil­i­ty test­ing of dielec­tric stacks and/​or capac­i­tors, for exam­ple TDDB, BTI, stress tests, HTOL, cycling, or similar.
- Good under­stand­ing of High‑k dielectrics and met­al-insu­la­tor-met­al (MIM) or met­al-oxide-semi­con­duc­tor (MOS) structures
- 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.
