The TI Prime adhesion promoter improves resist adhesion on substrates such as Si or glass. TI Prime contains Titanium, for this reason TI Prime should not be used where a contamination with Titanium could be a problem.
In contrast to HMDS, TI Prime is applied via spincoating, where a sub-mono layer is adsorbed onto the surface. In a subsequent ... the surface is activated. After cooling down the fusion should be applied.
