Pdms thickness vs spin speed
Spletnique.30 Xiu et al. studied the superhydrophobicity PDMS/PTFE composites applied on top of Si wafer via dip-coating, bar-coating, or spin-coating.31 Tropmann et al. used PDMS/PTFE composite particles and CF 4/O 2 plasma treatment for isotropic superhydrophobic PDMS surface.16 In this study, aluminum plates were used as the … SpletTwo concentrations, Chloroform:PDMS = 2:1 and 1:1, are used in order to obtain the films with the thickness ranges from approximately 7 to 20 µm. Under each spin speed, ramping speeds of 1000, 2000, and 4000 RPM/sec are used to study how spin speed and/or ramping speed affect the uniformity of the film thickness.

SpletThe size of the container will define the quantity of PDMS you need for the wanted thickness of your devices. For the size of a 4 inches substrate, 40g of PDMS will give you about 5mm-thick devices. If some bubbles appear during the pouring you can remove them with a needle or putting back your wafer under vacuum. SpletThe combination of spin speed and time selected for this stage will generally define the final film thickness (Meyerhofer 1978, Miitzi et al. 2004). In general, higher spin speeds and ...
