Improving Wafer Manufacturing Processes with Automated Equipment
Automated wafer fabrication equipment can improve semiconductor manufacturing facility performance, but all the associated process settings must be programmed properly. Before the manufacturing process can be implemented on a fully automated wet bench station, the settings, timing and other parameters have to be fine tuned. As circuit geometries and micro-structures become smaller and more tightly packed, the […]
How Specialized Wet Bench Equipment Improves the RCA Clean Process
The RCA clean process removes contaminants from the surface of silicon wafers so that additional wet process semiconductor manufacturing steps can take place. The process consists of two steps, with the SC1 step removing organic compounds and the SC2 step dislodging any remaining metallic residues or particles. Specialized wet benches ensure that contaminant and particle removal is […]
How Wet Bench Stations Are Designed for Ergonomics and Safety
To etch and clean silicon wafers, wet bench stations use aggressive and toxic chemicals that have to be handled carefully. Ergonomic design ensures that employees don’t have to perform risky or strenuous maneuvers in normal operation of the facility. To load trays, control processes and dispose of waste, employees should not have to lift especially […]

How Specialized Manufacturing Equipment Provides Safety for Using Solvents
Semiconductor manufacturing solvent applications use specialized wet bench equipment to reduce the risk of fire and explosions from volatile solvents such as acetone. Solvents are used for operations that include stripping, cleaning and pattern transfers, and their inflammable nature means that the equipment has to meet stringent safety regulations. Safety measures focus on ensuring electrical […]
Why You Need a Wet Bench Manufacturer with In-House Expertise
As semiconductor manufacturing becomes more complex, there is an increasing demand for custom solutions to special applications. Standard systems often can’t take into account the combination of multiple steps required to produce an etched silicon wafer. Instead they end up creating inefficiencies with poor quality output. Custom solutions can consider each separate requirement and can […]
How Software Controls Support Unique Wet Processing Requirements
Automated software control systems can help improve wet bench operations but the software has to be flexible to meet the unique needs of a wet processing application. Software controls increase dosage accuracy, timing reliability and process safety but process parameters or even the process itself can change as regulations tighten, customer requirements change and suppliers […]
Why Custom Wafer Cassettes Are an Essential Part of Wet Bench Equipment
Custom wafer cassettes made of specified materials or with specific physical characteristics are often needed in wet bench equipment for some applications. Research labs and universities may create unique semiconductor prototypes and start-ups may need sample semiconductors for testing. In each case, off-the-shelf carriers with the required characteristics are often not available. Custom wafer cassettes […]
5 Important Things to Know When Buying Wet Bench Stations
Because semiconductor manufacturing relies on a large number of process steps and complicated sequencing, wet benches need to be tailored to meet requirements for a specific application. Before focusing on the process-specific requirements, there are general questions that should be answered. This helps narrow down the selection criteria before making the purchasing decision. General questions […]
How Fully Automated Wafer Fabrication Equipment Improves Process Control
As the microscopic structures etched on silicon wafers become more complicated and densely packed, precise process control and the elimination of particle contamination become increasingly important. The accuracy of chemical dosages and the timing of steps have to be consistent and the handling of wafers must be reduced to a minimum. Fully automated wafer fabrication […]
