Scalable Mass Production & Continuous Iteration – From Sample Validation to Reliable HVM

The key to successful mass production is “reproducible consistency” and “iterable performance.” Zhuji’s 12 continuous production lines support two product lines in parallel: CVD SiC / TaC‑coated graphite components (thermal‑field structural parts) and CVD SiC Source (PVT feedstock). Copy‑Exact + SPC lock batches; failure analysis / growth feedback loops back into design and recipes.

Mass‑Production Assurance vs. Continuous Improvement
(Dual Track · Dual Product Lines)

Scalable Mass Production (HVM) Assurance	Lifetime / Crystal‑Quality Continuous Improvement
Multiple large multi‑zone CVD furnaces High‑density loading · consistent thermal/flow fields 12 vertically integrated lines Coated parts at 10k‑piece scale · Source by batch	Off‑line SEM / cross‑section diagnosis Source: customer growth‑feedback closed loop Locate wear, micro‑cracks, thermal stress Optimize block specs and purity window
Copy‑Exact lock‑in: Raw‑material batches · CNC route · gas purity Ramp profiles · chamber pressure Source: synthesis parameters & block specs	Structural / specification redesign: R / chamfer / local film‑thickness gradients Source block size & charge‑density optimization
SPC full‑process monitoring: Film thickness · roughness · resistivity Source: purity · particle size · density Traceable · process capability under control	Dynamic recipe fine‑tuning: SiC crystal orientation / TaC stoichiometry Source: adapt to customer PVT process upgrades

Customer‑Perceptible Advantages

Batch stability

Copy‑Exact reduces batch‑to‑batch variation; Source feedstock specifications can be written into long‑term supply agreements.

Iterable performance

Coated parts use chamber data for lifetime extension; Source uses crystal‑growth data to optimize block and purity.

Dual‑line capacity ready

Thermal‑field coated parts and PVT feedstock share the same control logic from sampling to volume production.
