Throughout wafer manufacturing, few steps are as critical as the D.I. (deionized water) rinse cycle. In most cases, your product is exposed to more D.I. water than any other process fluid. For this reason, a truly effective rinsing system can contribute dramatically to the reduction of particles and defect densities. A considerable amount of time has been given to help you make this transaction into our DR series quick dump rinser easy and affordable. Whether it’s upgrading your existing rinsing line or installing new wet process station we have the plan that will work best for you.
Our overall DR series Quick Dump Rinser is designed with two major features. One: Easy installation into new or used equipment and two: Low DI water consumption due to our rinse features.
Superior and consistent rinsing is achieved by (1) strategically located D.I water spray nozzles, (2) bottom filling (3) N2 agitation and (4) bottom fill that creates a vortex agitation in the rinse tank (optional).
The interior volume of the DR Series Quick Dump Rinser was reduced to minimum size relative to the wafer cassette. This, along with a 360˚ overflow weir and rapid dump time ensures that all large and small contaminants are quickly removed from the surface of the wafer and surrounding areas, thereby preventing recontamination of the wafer.
Modutek’s C15sa Rinser Controller is specifically designed for use with the DR Series Quick Dump Rinser wafer rinse system and provides a high degree of process flexibility. The user has the ability to program dump cycle, fill cycles, start cascade and spray delay. In addition, our C15sa controller has the ability to be programmed for resistivity and incorporates an access code which prevents tampering with the program.
In order to rinse to resistivity, the DR Series is used in conjunction with the Modutek Resistivity Monitor RM30a (optional feature). The RM30a has the ability to monitor resistivity and temperature inside the DR series rinser as well as incoming water into the wet bench. Once resistivity setting is reached inside the Quick Dump Rinser the rinse cycle discontinues at the next full level. This results in a process specific rinse, ensuring that a minimal amount of DI water is used.
In addition to all of these features Modutek’s Quick Dump Rinser is designed for new or used wet bench installations. With this design you can easily upgrade your old rinser and not incur the cost of a new wet bench. The water savings and the increased throughput will help cover the cost of the overall upgrade.
