Multi-layer SU-8 mold

This custom SU-8 master mold is perfect for your lab production of microfluidic chips. A cost-effective and useful tool for soft casting polymers (like PDMS) as well as hot-embossing processes (COC, PMMA, flexdym...).

 

Up to 4 SU-8 layers can be patterned with high aspect ratio on silicon substrates:

 

Microstructure layout

Microstructure layout should be provided by customers in an appropriate file format (.CIF, .DWG, .DXF) or they can be adapted to a correct format by our partner. After the revision of the layout, previously to the manufacturing, a PDF file will be provided to customer for the final approval of the design. The main aspects to be considered in the design of the microstructures:

 

  • File format: CIF, DWG or DXF files. Other formats as DXF may be accepted. All the structures should have closed contours. Any adaptation of the provided file will bring an extra charge.
  • Effective area: Layout must be fixed on 90 mm diameter of the wafer.
  • Dicing: The cutting lines should be drawn in case they are needed.
  • Multi-layer Molds: Alignment marks should be provided for the different layers

    Characteristics

    • Mold dimensions: 4 inch wafers (~100 mm). The effective area for the structures in the Mold is 90 mm Ø.
    • Substrate material: Silicon (other substrates such as glass or polymers, may be available on demand)
    • Structures material: SU-8 resin
    • Structures layers: Up to 4 layers
    • Typical aspect ratio: 1:3 (Width:Height). Other aspect ratio available on demand.
    • Minimal features: Height: 15 μm / Width: 10 μm
    • Tolerance: Height: <10%/ Width: <2 μm
    • Silicon wafer could be cut on smaller rectangular pieces in order to get individual masters. Other technical features can be fulfilled on request

     

      The following services are available on demand: 

      • Dicing in smaller pieces 
      • Design (non CIF files) 
      • Microstructures width <10 µm

       

      Applications

      Master molds for the microfabrication of customized microfluidic chips, MEMS, MOEMS and general soft-lithography.
