Automated Recovery System of Nano Contaminants (NAC Series)

Automated Recovery System of Nano Contaminants
(NAC Series)

NAC-302 NAC-304 NAC-316
About NAC Series
Obtained International Patent for bevel recovery.
The world's top-class function and technology in collecting hydrophilic surface.

● High-efficiency equipment to perform following process on silicon wafers by automatically;
VPD Process -> Scanning wafer surface and sampling contaminants -> Dilution of sampling solution

● An extremely effective device when it is necessary to take a sample from a large number of wafers at one time and analyze it.

● Sampling nano metal contamination from surface and sides (bevel parts) of silicon wafers.

● Able to collect contamination of both hydrophobic and hydrophilic wafer surfaces.
* Please note that bevel parts are when hydrophobic wafers only.

● Can process bulk etching.

● Uniformity / Flatness of wafers after etching process is within 10%.

● A function of measuring and diluting the sampling solution, and prevents the work from continuing with the
solution remaining on the wafer.

● Double door prevents the acid atmosphere in devices from mixing with contaminants on the operator.

● Automatically clean the liquid holder used for sampling. It will lead to saving time of operators
(Compatible with both normal and bevel holders).

There has been a significantly high need for the device that performs all following process automatically in these days
for the purpose of reducing contamination (Applicable by NAC-316);
Bulk etching -> Sampling contaminations -> ICP-MS connection & elemental analysis
