VPG+ 200 and VPG+ 400

Multi-Purpose Volume Pattern Generators

Our Multi-Purpose Volume Pattern Generators are perfectly suited for the production of standard photomasks as well as for i-line resist applications. An ultra-high-speed exposure engine and automated alignment capability both contribute to systems that excel through high resolution, outstanding image quality, and fast throughput.

Our VPG+ 200 and 400 systems present a perfect solution for applications that use i-line resists such as SU-8 and IP 3600, for example for rapid prototyping applications in microfluidics. In combination with their high speed and resolution, the VPG+ 200 and 400 therefore provide an excellent alternative to an i-line stepper.

Typical applications for the smaller exposure area members of the VPG+ family include such demanding fields as MEMS, advanced packaging, 3D integration, LED production, and compound semiconductors.

Advanced Packaging

The VPG+ series present the solution to fabricate high quality photomasks required for advanced packaging applications. For some applications, e.g Through-Silicon-Via (TSV) for 3D integrated circuits, direct write lithography is currently the only available advanced packaging solution. The VPG+ series of maskless lithography systems offer high speed, automatic distortion compensation and excellent resolution in order to master these applications.

Mix&Match approach

The IMS Gate Forest® technology is a “sea-of-gates” mixed-signal gate array integrating analog and digital functionality on a single chip. The microelectronic elements on the master can be individually configured by adding the respective contacts. In a Mix&Match-approach, stepper lithography patterned the CMOS masters, and personalized contacts and metallization layers were added using VPG 400 laser lithography. Courtesy of IMS Chips
