S hitrim razvojem umetne inteligence in visokozmogljivega računalništva se povpraševanje po računalniški moči in električni energiji raste eksponentno, saj predstavlja dvojne izzive čipov za upravljanje moči v smislu gostote moči in učinkovitosti . V tem kontekstu se čipi za upravljanje moči razvijajo v višino, ki se nahaja v višini pasivnih komponent, ki dosežejo visoko-denimo moči, da dosežejo visoko-denitveno moči, da dosežejo visoko denizijsko moč, da dosežejo visoko denimo moči, da dosežejo visoko denimo moči, da dosežejo visoko-denitveno moči, da dosežejo visoko denizijsko moči, da dosežejo visoko-dimenzionalno moči, da dosežejo visoko-dimenzionalno moči, da dosežejo visoko-dimenzionalno moči, da dosežejo visoko-dimenzionalno moči, da dosežejo visoko-denizionalno moči. Silicijeve pasivne komponente, ki temeljijo na siliciju, so se približale fizičnim omejitvam, zaradi česar je težko izpolniti prihodnje zahteve . dr . Gordon Moore, soustanovitelj Intela in predlagatelja "Moorejevega zakona", je poudarjeno (zbornik IEEE, 1998, 82) Elektronika . Čeprav so nedavni napredki mikroelektrokemičnih superkondenzacij pokazali visoko gostoto kapacitivnosti, njihove notranje statične značilnosti naredijo neprimerne za integrirana vezja, v katerih prevladujejo visokofrekvenčni akasti signali .
Recently, the research team led by Professor Wang Xiaohong from Tsinghua University's School of Integrated Circuits achieved a breakthrough in studying the dynamic response limits of high-frequency supercapacitors. For the first time, the team experimentally quantified the upper frequency limit of supercapacitor dynamic response. Using micro/nanofabrication techniques, they constructed an absolutely planar ideal electrode with a pore-free structure and eliminated interference through parasitic capacitance shielding and external phase-locked loop amplification, enabling precise measurement of the supercapacitor's dynamic response frequency limit. Building on this, the team innovatively proposed the concept of a "dielectric-electrochemical" asymmetric capacitor-where the device primarily relies on electrochemical effects at low frequencies and dielectric effects at high frequencies-achieving breakthroughs in both frequency response and capacitance density. The fabricated micro-supercapacitor chip exhibited a characteristic frequency exceeding 1 MHz, six orders of magnitude higher than commercial supercapacitors, covering the operating frequency range of mainstream power vezja .
Previously, the team successfully overcame the incompatibility between electrochemical devices and semiconductor fabrication processes by proposing a cross-domain heterogeneous integration theory and three-dimensional architecture. They established a CMOS-compatible wafer-level fabrication process and developed the world's first integrated electrochemical power supply rectification and filtering chip.
