The Etch Chamber Battlefield: BCNC Competitive Analysis

Synthetic quartz QD9/QD9+ and the competitive landscape of etch consumables

Published: 2025-10-13 · Semiconductor materials competition · Naver Blog

Investment decisions are your own responsibility. This material is research and is not a buy or sell recommendation.

0. Bottom line first

BCNC’s key issue is QD9+ material internalization, not just QD9 as a product. Making the raw material in-house changes cost, supply stability, and design flexibility. The challenge is competing with TCK, Hana Materials, Worldex, and KNJ, which already have customer, equipment-maker, and raw-material moats.

1. Etch consumables market

Official fact: Focus rings and electrodes in etching affect plasma control, wafer uniformity, yield, and performance. 3D NAND layer increases and sub-10nm processes accelerate adoption of high-performance materials such as SiC and synthetic quartz.

2. BCNC product axis

Official fact: QD9 is described as BCNC’s main synthetic-quartz product, accounting for about 70-73% of revenue. The source cites about 50% longer lifetime than natural quartz, fewer particles due to no micro-bubbles, and high UV transmittance.

Official fact: QD9+ is a strategy to produce internally synthetic-quartz raw material previously imported from suppliers such as Corning. The source says the hollow-cylinder form can reduce machining time and raw-material loss, with potential raw-material cost savings of up to 60%.
