1. Light-sensitive chemical materials used in semiconductor manufacturing and printing to create precise patterns on surfaces by selective exposure and development.
Usage: technical; plural form; singular is photoresist; commonly used in microelectronics and lithography

Examples

• The semiconductor factory uses advanced photoresists to etch circuit patterns onto silicon wafers.
• Positive photoresists become soluble when exposed to ultraviolet light.
• Engineers carefully select photoresists based on the required resolution and processing conditions.
• The quality of photoresists directly affects the precision of microchip manufacturing.
• Modern photoresists enable the production of smaller and more complex electronic components.
