Ultra-low leak­age and sta­ble elec­tri­cal para­me­ters at ele­vat­ed tem­per­a­ture are crit­i­cal for next-gen­er­a­tion semi­con­duc­tor appli­ca­tions. Reduced leak­age cur­rent min­i­mizes stress, lim­its heat gen­er­a­tion, and improves long-term sta­bil­i­ty – key require­ments in AI data cen­ters and advanced com­put­ing sys­tems where pow­er den­si­ty and ther­mal man­age­ment are deci­sive factors.

On Feb­ru­ary 5 we report­ed that the CNF-MIM capac­i­tors showed sta­ble per­for­mance in a 1,000-hour reli­a­bil­i­ty test. Now we can announce that an inde­pen­dent third-par­ty oper­a­tional life test has ver­i­fied sta­ble per­for­mance over 1,000 hours under applied volt­age — with zero fail­ures and no observed degra­da­tion in capac­i­tance, equiv­a­lent series resis­tance (ESR), or insu­la­tion resis­tance. Leak­age cur­rent remained in the picoam­pere range, with an insu­la­tion resis­tance of 1,000 GΩ at rat­ed voltage.

Val­i­da­tion under strict con­di­tions
The exter­nal life test sub­ject­ed the CNF-MIM capac­i­tors to con­tin­u­ous oper­a­tion for 1,000 hours at 85°C with con­stant volt­age bias, sim­u­lat­ing pro­longed use in ther­mal­ly demand­ing semi­con­duc­tor envi­ron­ments such as AI accel­er­a­tors, advanced proces­sors, high-per­for­mance com­put­ing (HPC) sys­tems and RF appli­ca­tions. Test­ing at an ele­vat­ed tem­per­a­ture rep­re­sents an accel­er­a­tion of aging mech­a­nisms, pro­vid­ing con­fi­dence in long-term field reli­a­bil­i­ty and oper­a­tional stability.
