Cleaning : Wet and Dry Etching
Cleaning : Wet and Dry Etching for Advanced Semiconductor Processes
Wet and dry etching are essential processes in semiconductor research, process development and production environments. These processes remove surface contaminants, prepare wafer surfaces, and enable controlled material removal as part of R&D and pre-production workflows.
MDC Europe provides both single wafer and batch wet processing approaches, each optimized for different levels of control, throughput and process flexibility. Our solutions support a wide range of chemistries, wafer types and application requirements, enabling reliable and repeatable performance in characterization and process evaluation tasks.
Process Context
In semiconductor workflows, wet processing is used throughout material preparation, surface treatment and front-end / back-end operations. Effective cleaning and etching ensure surface quality, repeatability and process integrity prior to subsequent steps such as deposition, patterning or electrical characterization.
Single Wafer vs. Batch Approach
Wet processing can be executed using two primary approaches, each with distinct operational profiles:
Single wafer wet processing
Optimized for precise, individual wafer control, rapid process iteration and minimal cross-contamination. Ideal for process development, advanced material evaluation and R&D characterization.
Batch wet processing
Designed for processing multiple wafers simultaneously with high throughput and cost-effective operation. Appropriate for established cleaning or etch steps where uniformity requirements are met at the batch level.
This structure allows selection of the most suitable approach according to process stability, throughput requirements and control priorities.
Typical Applications
Wet cleaning and etching are deployed in:
- Pre-deposition surface preparation
- Photoresist residue removal
Oxide/film etch steps prior to analytical measurement - Surface conditioning for electrical characterization
- Process development and comparative evaluation
