Segmentation by Product Type

The viscosity reducing film market can be divided into two primary product categories based on the activation method:

1. UV Viscosity Reducing Films

UV-activated films account for over 90% of market share and are the industry standard for semiconductor photolithography processes. These films utilize ultraviolet light to initiate the viscosity reduction mechanism.

  • Market Insight: The dominance of UV films stems from their compatibility with existing semiconductor fabrication equipment and proven reliability in advanced nodes.

  • Trend: Leading manufacturers are developing low-temperature UV films to meet the requirements of emerging 3D NAND and advanced memory applications.

2. Thermal Viscosity Reducing Films

Thermally activated films represent a niche segment, primarily used for specialized applications where UV exposure is impractical or where high-temperature processing is required.

  • Market Insight: While representing less than 10% market share, thermal films are finding growing adoption in power semiconductor and MEMS device manufacturing.

  • Trend: Development of low-outgassing thermal films is creating new opportunities in vacuum deposition processes and compound semiconductor applications.
