The subject of the invention is a device for chemical or biological analysis comprising a carrier () containing a plurality of analysis sites able to fix a chemical or biological reagent, in which the analysis sites are formed of microdishes () hollowed out of the carrier, the side walls and the bottom of the microdishes and the areas of the carrier surface surrounding each microdish, called microdish edges, being made in at least one hydrophilic material (), and the planar areas of the carrier arranged between the areas surrounding the microdishes being made in a hydrophobic material (). Drops () of reagent are therefore guided into the microdishes () on account of the hydrophobic areas (). It is therefore possible to increase the density of analysis sites on the carrier.

Photosensitive film which is photosensitive in a given wavelength range comprises at least one silicon-containing polymer, at least one salt which can be converted into a Brunsted acid by irradiation and optionally at least one photosensitizer. The silicon-containing polymer-based photosensitive film can be used as a masking resin in a lithography process for producing electronic components.
