Wet Benches For Semiconductor Etching Process

By Roy van Rivero


Wet etching used for semiconductor substrates processing is performed with the help of high tech equipment called wet benches (also known as wet process stations). Typically, these equipment are a fully-automated system that facilitates wet cleaning, etching, stripping, texturing, and plating operations. Wet benches are designed to have several tanks or modules that contain process solutions.

Wet benches can be configured so that they can fit according to your specific 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 -- the system includes either linear or rotational transfer from one module to another (2, 3 or 4 tanks in the sequence).

Manual wet bench -- this configuration requires an operator to manually move 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 bench manufacturers - the industries they serve:

Electronics -- where semiconductors are used in many electronic products such as 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 -- also known as nanotechnology or microelectronic fabrication, a process that is used for the production of integrated circuits.

LED -- wet benches can also help in manufacturing high brightness LEDs at lower cost than other conventional processes.

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 -- this is another product that is produced with the help of wet bench manufacturers who help in the production of precise and reliable storage devices.

Wet bench manufacturers have been in circulation for quite a while and they continuously help several sectors, particularly the semiconductor's, in fulfilling their functions .
