Wet Benches And Wet Etching Process For Semiconductor

By Roy van Rivero


Wet benches are equipment used to perform wet etch process for semiconductor substrates. Generally, they are fully-automated and are used specifically in cleaning, stripping, texturing, and plating operations. They are designed to have several tanks (also known as modules) that contain process solutions.

Several specific configurations can be done with wet benches so that they can fit to your unique needs. They can be:

Fully-automated wet bench - it includes load and unload stations; the substrates are fully-processed and dried by the end of the sequence.

Semi-automated wet bench -- designed to have either linear or rotational transfer from one module to another (2,3 or 4 tanks in the sequence).

Manual wet bench -- with this, an operator is employed and manually moves cassette from tank to tank.

Intelligent process station -- this configuration is designed to have the components of a fully-automated system with additional feature called process control monitoring.

Wet benches for semiconductor wet etching - the industries served:

Electronics -- electronic products manufacturers are an example of industry being served by wet bench manufacturers as semiconductor components are being used in various electronic devices (e.g. mobile phone, laptop and desktop computers, radio components, etc.)

Solar -- semiconductor components are also used for the production of solar panels utilized as an alternative energy source; it is also being used in solar panel system commonly installed in communication satellites and other astronomical endeavors.

MEMS -- the industry of nanotechnology or microelectronic fabrication is also benefiting from wet bench manufacturers as semiconductor substrates are also being used in the production of integrated circuits.

LED -- the use of wet bench can help produce high brightness LEDs at lower cost than other conventional methods.

Bio-medical -- the wet bench manufacturers is also helping the bio-medical industry as they provide the necessary equipment needed in manufacturing technologies vital to medical works such as biochips and biosensors.

Disk drive -- storage devices that you might be using today come from manufacturers that rely from wet bench manufacturers as they help in the production of mature, precise, and reliable storage products.

Wet bench manufacturers have been in business for quite some time and they continuously help several sectors, particularly those that rely on semiconductor components in their manufacturing processes.
