Why Hana Materials Silicon and SiC Parts Track Fab Utilization

The company makes consumable parts for etch equipment. Hana Materials produces silicon and silicon-carbide parts used in semiconductor etching. Electrodes and rings help maintain process conditions around the wafer in a plasma environment. These functions establish why the parts are used, but they do not disclose the equipment model, customer, replacement interval, or sales contribution attached to an individual item.

Company materials can confirm product applications while customer-level supply shares remain confidential. A dependence on a specific memory producer should not be supplied as an estimated fact. Product development, customer-equipment evaluation, qualification, purchase, shipment, use, replacement, and revenue must be supported independently rather than inferred from the general etching market.

Higher utilization can increase replacement opportunities. Consumable parts wear while equipment operates, so wafer input and equipment operating time can influence demand. Recovery in utilization at an existing line may therefore support sales even without construction of a new fab. This mechanism differs from demand created by the initial installation of a new etch tool.

Replacement intervals vary with process conditions and part materials. An industry average cannot be applied as Hana Materials' actual sales volume. The number of wafers processed, hours of tool operation, inventory held by customers, qualification status, and purchasing schedules can prevent demand and reported revenue from moving in a simple fixed ratio.

SiC addresses durability and difficult process conditions. SiC parts can use heat resistance and resistance to plasma in demanding etch environments. As semiconductor stacks become more complex, quality requirements for components can rise. This explains the technical opportunity for SiC, but it does not mean silicon parts are replaced immediately or in every process.

Customer qualification, production yield, and price must be considered with the material's technical advantages. A successful internal development does not establish customer certification; certification does not establish an order; and an order does not establish shipment, completed use, replacement demand, or recognized revenue. Each material and application can follow its own approval timeline.

A new factory raises capacity and fixed costs together. Expansion intended to meet demand can increase supply capacity. If utilization remains low after completion, depreciation and other fixed costs can weigh on results. A production-facility announcement therefore cannot confirm higher profit, and its stated capacity should not be counted as sales before the factory operates and customers approve its output.

The stages are investment decision, construction, equipment installation, customer qualification, and normal operation. Cash flow and growth in property and equipment help show the burden during that sequence. Even normal operation establishes available production; actual orders, shipments, customer acceptance, and revenue are still needed to demonstrate commercial use of the capacity.

The May Filing Quantifies the Commercial Consumables Business. Hana Materials' quarterly report filed on May 14, 2026 identifies silicon and SiC electrodes and rings for etch processes as its main manufacturing and sales business. These products are current, repeatedly sold commercial consumables rather than planned development projects.

The same report showed first-quarter consolidated revenue of about KRW 93.4 billion and operating profit of about KRW 21.3 billion. The results demonstrate revenue from the installed etch-equipment base and fab operation, but do not disclose adoption rates by customer or equipment model.

The next evidence is silicon and SiC product mix, inventory and sales volume, customer-fab utilization, and qualification and repeat orders for newer parts. News about higher-layer etching or capital spending should not be converted directly into Hana Materials' sales growth.

Product mix and customer diversification shape profitability. The sales mix between silicon and SiC parts, raw-material prices, and factory utilization can affect margins. Concentration in a customer or in the memory cycle can also increase volatility. The source does not disclose a customer-specific share, so diversification must be judged from reported information rather than industry assumptions.

Product revenue, production-facility utilization, inventory, capital expenditure, and new-customer qualification are the useful checks. A quarterly result should be read by combining the operating pace of customer fabs with the pace of Hana Materials' expansion. Technical development and capacity plans matter, but repeat replacement orders and reported revenue supply the later evidence.

Calculating Replacement Demand for Etch Parts. If an installed base of 500 tools uses two silicon rings per quarter, demand is 1,000 rings. If 100 tools using SiC rings consume one each per quarter, total demand is 1,100 rings, with the material mix affecting average price.

If longer part life or customer reuse reduces replacement frequency, do not project demand from fab utilization alone.

Installed tools multiplied by replacement frequency and price by material is the company-specific formula that explains consumables revenue.
