Reviewing KNJ’s Investment Points and Business
A summary of growth points as the company shifts from display equipment to CVD-SiC semiconductor parts
0. Bottom line first
This is not a recommendation to invest in the company; it is a memo for my own review. KNJ is growing around CVD-SiC Focus Rings, and I see the investment points as demand growth from replacing existing silicon rings, the reduction of the display-equipment business, focus on the new industry, and timely facility investment. China-bound sales may also be increasing, but that is an estimate.
1. Investment Points
I am briefly reviewing KNJ, where I executed an investment today. I believe demand is growing as CVD-SiC rings replace the silicon rings that had been used before. In a market where I think demand will exceed supply for the time being, I see investment merit in the company boldly exiting the legacy display-equipment business, focusing on the new industry, and continuing facility investment at the right time. Sales to China-bound customers appear to be increasing, but that is an estimate.
Market growth
CVD-SiC rings are replacing existing silicon rings, and demand in semiconductor manufacturing processes is summarized as rising sharply.
Business transition
The company is withdrawing from display equipment and refocusing capabilities around semiconductor components.
Capacity expansion
It continues timely facility investment to respond to growing demand.
Official fact: The source image is attached with the caption “Facility expansion history by Butler.”
2. Business Status from IR Materials
The company is summarized as having exited the display business due to worsening downstream display conditions and shifted direction toward CVD-SiC components.
| Category | Source summary |
|---|---|
| Reduced legacy business | Display panel manufacturing equipment, Edge Grinder, inspection equipment |
| Core transition business | CVD-SiC components, silicon-carbide-based consumable parts used in semiconductor manufacturing processes |
| Product feature | A product group that replaces Si materials and strengthens durability and performance |
| Main customers | Working with major Korean companies including Samsung Electronics, SK hynix, and Samsung Display |
| Global expansion | Supplying products to major overseas display and semiconductor manufacturers, including China |
3. Business Strategy
- Strengthening product competitiveness: Focus on developing CVD-SiC components with higher durability and heat resistance than existing Si-material parts.
- Expanding R&D: Strengthen research and development capabilities for continuous technology innovation and develop new products that meet high-performance and high-precision manufacturing requirements.
- Market diversification: Secure new customers and expand regional market share. The original post estimates that this may be China OE-bound.
- Product-line enhancement: Strengthen the lineup in step with growth in memory semiconductors and highly integrated circuit markets.
Interpretation: The core of this company is not merely that it makes semiconductor parts, but that it has changed resource allocation away from a loss-making or slowing display-equipment area toward CVD-SiC parts with stronger demand.

5. My Checkpoints
- Check how quickly CVD-SiC Focus Rings replace existing silicon rings.
- Watch whether the supply shortage actually continues and whether KNJ’s expansion converts into revenue.
- Since the China-bound sales increase is an estimate, confirm it later through customer and sales data.
- Track whether the company can receive a semiconductor-components valuation after reducing the display-equipment business.
