How Specialized Equipment Improves Silicon Wet Etching Processes
Results from common wet etching processes such as KOH and Piranha etch can be improved with the use of specialized equipment. Depending on the process, key parameters can be controlled especially well and innovative procedures can reduce particle counts. When specialized equipment is used in silicon wet etching processes, wafer output can increase, defects can […]
How Quick Dump Rinsers Improve Silicon Wet Etching Processes
When silicon wafers in a wet etching process need rinsing, quick dump rinsers provide fast and effective rinsing of chemicals and particles. In semiconductor fabrication lines such as those of semiconductor manufacturers and research labs, silicon wafers are etched with chemicals. Once the required structures and current paths have been etched into the silicon, the chemicals have […]
How High Temperature Quartz Tanks Improve Silicon Wafer Processing
The silicon wafer processing steps that include etching or cleaning the wafers with aggressive chemicals require tanks to hold the chemical process. Quartz tanks are impervious to the acids and bases used in wet process stations and the high temperature tanks can include heating and re-circulating. Modutek is a leader in the design and manufacture […]
How Are Isotropic and Anisotropic Processes Used to Improve Silicon Wet Etching?
The microscopic structures produced by silicon wet etching can be created with a high degree of precision by using both isotropic and anisotropic processes. Isotropic etching is faster but may etch under masks to create rounded shapes. Anisotropic etching can be controlled more precisely and can produce straight sides with exact dimensions. In each case, […]
How Process Controls Improve Silicon Nitride Wet Etching Results
The silicon nitride wet etching process uses a phosphoric acid solution in water to etch mask material quickly and reliably but the process is hard to control. Etching speed depends on the concentration of the solution and the bath temperature. Adding water to the solution to control the concentration is dangerous and, at the same […]

How Quartz Tanks Improve Wafer Manufacturing
The aggressive chemicals used in wet process wafer manufacturing have to be contained in process tanks that can resist etching and corrosion while remaining inert. Depending on the application, a process may require heating, filtration or the regular addition of chemicals. Quartz tanks from Modutek are made from semiconductor grade flame-polished quartz and are impervious […]
Customized Table Top Chemical Process Tanks
For small operations and specialized applications requiring semiconductor fabrication capabilities it often doesn’t make sense to construct wet processing lines that produce products at volume. Table top process tanks can allow research labs, universities and start-up companies to produce single parts or low-volume output. These organizations may need proof of concept components or prototypes for […]
