Segmentation by Product Type

The 193nm photoresist market can be divided into four key product categories, reflecting variations in formulation, application method, and performance characteristics tailored to specific lithography needs.

1. Dry 193nm Photoresist

Dry 193nm photoresists are typically applied in a solid film form or through spin-coating processes that result in a uniform, solvent-free layer on wafers. These resists are prized for their stability, ease of handling, and ability to achieve high aspect ratios in patterning without excessive swelling or defects.

• Market Insight: Dry photoresists dominate the segment due to their compatibility with high-volume semiconductor production lines. They are especially favored in logic and memory chip fabrication where precision and throughput are paramount. However, as node sizes shrink further, there’s a push toward resists with even lower line-edge roughness to minimize defects.

• Trend: Major foundries in Asia, such as those in Taiwan and South Korea, are increasing adoption of dry 193nm resists for 7nm and below processes, balancing cost with performance in dry etch steps.

2. Wet (Immersion) 193nm Photoresist

Wet 193nm photoresists are formulated for immersion lithography, where a liquid medium like deionized water is used between the lens and wafer to enhance resolution. These resists incorporate hydrophobic groups to prevent water penetration and leaching, ensuring clean, high-fidelity patterns.

• Market Insight: Immersion variants are gaining traction as the go-to solution for sub-10nm nodes, offering superior resolution compared to dry methods. Demand is surging in advanced DRAM and NAND flash production, where multiple patterning techniques rely on these resists.

• Trend: With the proliferation of EUV lithography hybrids, wet 193nm resists serve as a bridge technology, particularly in regions investing heavily in chiplet designs and high-performance computing.

3. Positive-Tone 193nm Photoresist

Positive-tone 193nm photoresists become soluble in exposed areas upon irradiation and development, allowing for precise definition of features. They are chemically amplified, using acid catalysts to amplify the exposure effect, which improves sensitivity and reduces dosage requirements.

• Market Insight: This category leads in market share, driven by its widespread use in gate and contact patterning in logic devices. Semiconductor giants prioritize positive-tone resists for their excellent contrast and minimal scalloping in profiles.

• Trend: Innovations in quencher additives are enhancing collapse margins for finer pitches, aligning with the roadmap for 5nm and 3nm nodes amid growing AI chip complexity.

4. Negative-Tone 193nm Photoresist

Negative-tone 193nm photoresists cross-link upon exposure, becoming insoluble and forming patterns in the irradiated regions. These are useful for applications requiring high etch resistance and are often employed in via-hole and trench formations.

• Market Insight: Though smaller in volume, negative-tone resists are crucial for specific interconnect layers where dry etch selectivity is key. Their role is expanding in 3D NAND stacking, where vertical structures demand robust masking.

• Trend: Research into hybrid positive-negative systems is underway to optimize double patterning schemes, supporting the transition to next-gen nodes as EUV adoption lags in cost-sensitive markets.
