A semiconductor fabrication facility achieved improved wafer yield, ultra-tight temperature uniformity (±2°C), and full emissions compliance by implementing Epcon’s cleanroom-compatible precision process oven with integrated VOC abatement. The system supports critical wafer coating and curing operations with HEPA-filtered airflow and integrated heat recovery, reducing energy consumption by approximately 28% and guaranteeing stable, 24/7 operation.
Semiconductor Manufacturing – Precision Process Oven & VOC Abatement System
Executive Summary
Project Overview
A semiconductor fabrication facility required advanced thermal processing equipment to support wafer coating, soft bake, and cure operations associated with photoresist and thin-film applications. These processes demand exceptional temperature uniformity and cleanliness to protect yield in high-value semiconductor production. In addition, solvent-based photoresists generated VOC emissions that required effective treatment without introducing contamination risks.
Epcon was selected to deliver a thermal solution capable of continuous, 24/7 operation within a cleanroom environment while reducing energy consumption compared to legacy equipment.

The Challenge
Semiconductor manufacturing presents some of the most demanding thermal processing requirements in industry. The customer faced challenges related to:
- Extremely tight temperature tolerances, requiring uniformity of ±2°C
- Zero tolerance for particulate or chemical contamination, necessitating a cleanroom-compatible design.
- Rising energy costs from older cleanroom ovens, requiring a high-efficiency solution.
- VOC emissions from solvents, requiring integrated abatement that would not compromise cleanroom integrity.
The Solution
Epcon engineered a cleanroom-compatible forced-convection process oven with integrated emissions abatement, meeting all ultra-clean and performance requirements.
Cleanroom-Compatible Precision Process Oven
Cleanroom-Compatible Precision Process Oven
- Uses indirect heating and precision airflow control to isolate the process from combustion byproducts.
- HEPA filtration ensures ultra-clean air delivery to the wafer process zone.
- The oven is integrated with a recuperative thermal oxidizer to treat VOC-laden exhaust streams.
- Recovered heat from the oxidizer is reused to preheat combustion air, significantly reducing overall fuel consumption and improving system efficiency.
- The entire system is engineered for stable, reliable continuous operation (24/7) within a cleanroom fabrication environment.
