Soft Lithography Stamps
|
|
Soft lithography is a low cost and highly accurate method for submicron patterning of 2D and 3D structures. The process, first described by Xia and Whitesides , requires the production of an accurate master pattern around which a polydimethylsiloxane (PDMS) stamp is cast. This flexible stamp carries the shape of the master pattern, and can be used to make multiple prints of the pattern in a variety of polymer resins.
The printing procedure can be performed outside of a cleanroom, thereby allowing micro-scale devices to be produced with minimal capital outlay. The article "Soft Lithography For Dummies" describes the soft lithography procedure and its capabilities.
Bandwidth Foundry produces soft lithography stamps of your designs, or can provide designs to your specifications. Multiple feature heights within the one stamp can be produced. Applications to the production of planar lightwave circuits and microfluidics devices are common.
For a quote, please contact us and let us know your requirements - on a routine basis we will need to know the following:
|
1. |
Required stamp geometry and size. |
|
2. |
The dimensions of your design (size of patterned area X-max and Y-max). |
|
3. |
Required depth of features. |
|
4. |
Writing polarity (i.e. are closed polygons meant to be raised or depressed)? |
|
5. |
CD (critical dimension). |
|
6. |
Required tolerance on CD. |
|
7. |
Required turn-around time. |
