Hubei Jiangcheng Laboratory said it has developed a 3D multilayer on‑chip capacitor with capacitance density exceeding 1,000 nF/mm2, targeting direct use in AI/GPU chips and high‑performance processors. The lab said the technology supports high‑compute, low‑power chip design and is undergoing process tape‑out and small‑batch trial production, with plans for scale-up in advanced packaging. The release described the capacitor as an ultra‑miniature energy buffer that smooths voltage during rapid current swings and complements HBM as an energy cache across nanosecond‑to‑second timescales to sustain GPU peak power.
