Abstract:
A method for making a conductive line which electrically connects with a node location on a substrate, comprising:forming a lower photosensitive material masking block over the node location, the lower photosensitive masking block comprising a positive image of a contact opening to the node location and while leaving the lower photosensitive masking block in covering relation over the node location, separately forming an upper photosensitive material masking block over the lower photosensitive masking block, the upper photosensitive masking block comprising a positive image of a conductive line;forming dielectric material around the upper and lower photosensitive masking blocks;removing the upper and lower photosensitive masking blocks from the dielectric material to leave a contact opening void and an overlying line void; andfilling the contact opening void and overlying line void with electrically conductive material to form a conductive line in electrical connection with the node location.
