ABSTRACT:
An element structure has a polyimide resin applied on a surface of a first substrate to a uniform thickness, and is subsequently heated to form a semi-cured polyimide layer. The polyimide layer is then cured to form a cured first polyimide layer. A polyimide resin is applied on a surface of a second substrate to a uniform thickness, and is subsequently heated to form a semi-cured polyimide layer. The polyimide layer is then cured to form a cured second polyimide layer. The cured first and second polyimide layers are pressed on each other and heated to a bonding temperature, thereby joining the polyimide layers together. Thus, the first substrate and the second substrate are combined with the polyimide layer being the bonded structure of the polyimide layers therebetween.
