4H‑SiC 웨이퍼 및 에피 층 생산을 위한 탄화규소 결정 성장 및 에피택시 장비

파키스탄용 2025년 제품 개요 및 시장 관련성

4H‑SiC crystal growth and epitaxy equipment sit at the foundation of the silicon carbide value chain, enabling local production of substrates and drift layers for high-voltage MOSFETs, Schottky diodes, and power modules used in UPS, VFDs, and grid-tied converters. For Pakistan’s textile, cement, and 강철 sectors—and the country’s expanding industrial parks—domestic access to 4H‑SiC wafers and epitaxial services reduces foreign exchange exposure, shortens lead times, and empowers technology sovereignty.

2025년에 이것이 중요한 이유:

  • Demand for SiC devices is accelerating in high‑efficiency rectifiers, three‑level inverters, and bidirectional converters that must perform reliably under heat, dust, and unstable grids common in Karachi, Lahore, and Faisalabad.
  • Establishing local crystal growth (PVT) and chemical vapor deposition (CVD) epitaxy capacity supports Pakistan’s industrial strategy by ensuring predictable supply for mission‑critical B2B projects (data centers, hospitals, process plants).
  • 4H‑SiC epi with tight defect control (BPD, TSD, TED) and uniform doping profiles enables higher device yields, >98% converter efficiencies, and improved reliability for continuous operations.
  • Integrated toolsets—from boules to epi reactors, metrology, and backend wafer handling—cut total cost of ownership (TCO) while enabling rapid customization (thick drift epi for 1.2–1.7 kV MOSFETs, low‑doped layers for diodes).

Sicarb Tech supplies complete, production‑grade 4H‑SiC crystal growth furnaces (PVT/sublimation), high‑throughput hot‑wall CVD epitaxy reactors, wafering and CMP solutions, and inline metrology—backed by the Chinese Academy of Sciences and more than 10 years of SiC manufacturing and equipment engineering.
