Chip manufacturing

The chip creation procedure is divided into several steps. These steps are summarized in the figure above. First one needs to create a mask (see c) in order to obtain a master (see d) starting from a silicon wafer (see a). For the specific procedure of mask and wafer creation, see Part I. Once the master is ready it can be used as a mold to create the PDMS chip.

Here is a non-exhaustive step by step presentation. For the precise procedure you can refer to our notebook protocol.

The PDMS mixture is precisely weighted. The ratio of organic polymer to curing agent is an important factor for a good chip consistency.
