Microfabrication Applications

As a CAD « power user », I find DW to be a great program to use, that I can work with quickly and efficiently. The flow of work for the user is quite well designed, and the user interface is optimized for the user. I think what sets DWT aside from most competitors is the extremely powerful programming language, which provides immense extendibility and customization of the entire program.

We would like to thank Design Workshop Technologies for supporting Lightwave Microsystems in our goal to be the world-leading manufacturer of integrated optical components. For over four years, Lightwave Microsystems has been using DW as our mask layout software of choice to build our integrated optical components. DWT has been supportive by responding to our specific needs and requirements. DWT has an excellent technical support team that is responsive and knowledgeable. We look forward to building a great business relationship in the future.

Cree Inc. utilizes DW as our preferred CAD tool for the implementation of, primarily, next generation microwave FET and microwave MMIC amplifier designs in SiC (Silicon Carbide), and GaN (Gallium Nitride). Refer to Cree’s website at www.cree.com for more information regarding specifications, target applications, partnerships, and customers. We have also employed DW in power device design including SiC power mosfets and schottky diodes. The power of the DW boolean tools has enabled designs that would have been previously too labor intensive to have been cost/time effective to pursue.

Dan Fritz – Test Engineer, Cree Inc.

I particularly appreciate the versatility of DW that we use to design photomasks for diffractive optics as well as for MEMS-like devices such as microbolometers, lightvalves or micromirrors. DW prevents any positioning error of MEMS on the CMOS circuitry because the design is made directly on top of the CMOS library. I also want to mention the GPE programming capabilities of DW for automatic generation of very complex structures that would be otherwise very difficult to build.

Here at Ultratech Stepper, Inc. we decided back in 1991 that it was time to purchase mask layout software to bring this capability in-house, rather than depend upon outside sources. After our investigation into the various options, we chose Design Workshop Technologies’ DW and have been using it for the past 12 years. We started with the Apple platform, and now have licenses for both the Apple and the PC platforms. We have completed cad layout for hundreds of Ultratech Stepper reticle designs for the steppers we produce, and have also found DW very useful for the verification of device layouts of our Customers. The ease of use of the Layout Editor of DW has always been a big plus.

Alan Walther – Senior Reticle Engineer, VEECO

At RSC, we’re an independent privately owned company focused on creating innovative technologies and delivering the winning technical edge in partnership with our customers. With intense time-to-market pressures our designers need proven layout software that works reliably and DW fills this need. DW is an impressive layout tool. Two outstanding features of DW are the native GDS database that guarantees seamless conversion and export of layout data to the GDS format, and the graphical programming environment (GPE) that gives access to all the capabilities of DW for automating advanced layout tasks.
