Abstract
In a thermomechanical process for planarizing a resist layer applied to a partly elevated carrier area, a resist structure, in particular an encapsulation for electronic components, is obtained. In this case, a dry resist sheet, formed of a composite of a temperature-resistant protective sheet and a photosensitive layer, is applied by its photosensitive layer to a surface of the carrier and the dry resist sheet is planarized under pressure and with heat. After which the photosensitive layer is exposed, and the protective sheet is removed and the photosensitive layer is developed.
