Technology Description: |
The μPG 501 is a micro pattern generator for direct writing applications. The system can be used for prototyping MEMS, Bio-MEMS, integrated optics, and microfluidics (a prime example is Lab-on-a-Chip devices), or any other application that requires high precision, high-resolution microstructures. The μPG 501 is equipped with a 10W light-emitting diode operating at 390 nm, a 600×800 pixel digital micro-mirror device, and a motorized stage to expose patterns on resist-coated substrates. The μPG 501 can expose standard positive and negative photoresists as well as UV-resists. The Heidelberg Software is compatible with GDSII, DXF, GERBER, CIF, BMP, and STL files. |

Writing Performance: |
Minimum feature size: 1 μm. CD uniformity (3σ): 200 nm. Write speed: 50 mm²/min. Address grid: 50 nm. Line edge roughness (3σ): 100 nm. Alignment accuracy (3σ): 200 nm. |
Sample Preparation Equipment: |
Laurell Spin Coater. The photoresist film coating Laurell WS-MZ spinner used is a programmable spinner operating at 100-1200 RPM. A hotplate is used for photoresist baking. A separate training session is required before new users are allowed to work independently with the photoresist coater. |
