Stepped Mandrel Structure for Parallel Semiconductor Structures

The patent applies preliminary action by depositing a mandrel layer and selectively removing material to form protrusions before the final structure is completed. These protrusions are created in advance to counteract the bending that will occur during subsequent fabrication steps, particularly during spin coating where capillary forces act on the parallel structures. The protrusions serve as pre-positioned support elements that prevent deformation before it happens.

The patent implements local quality by creating non-uniform protrusions at specific locations between the parallel structures rather than uniformly modifying the entire structure. The protrusions are selectively formed in regions where bending is most likely to occur, providing localized support where needed while maintaining the original structure elsewhere. This targeted approach addresses the deformation problem without unnecessarily complicating the overall design.

The patent uses preliminary action by forming protrusions on the mandrel layer before depositing subsequent materials. These protrusions are created in advance to maintain consistent spacing between parallel structures during the spin coating process, preventing the structures from bending toward each other and ensuring uniform gap formation throughout manufacturing.

The patent applies parameter changes by modifying the local geometry of the mandrel layer through selectively removed protrusions. This changes the physical parameters of the structure at critical locations, creating elevated regions that alter the distribution of materials during spin coating and maintain consistent spacing, thereby improving gap uniformity without sacrificing manufacturing efficiency.

The patent implements preliminary action by creating a stepped structure through selective removal of the mandrel layer before subsequent material deposition. This stepped configuration is established in advance to provide mechanical support that prevents bending of parallel structures, ensuring good electrical properties are achieved without requiring complex fabrication processes or additional materials.

The patent uses the mandrel layer as an intermediary structure that is selectively modified to create protrusions. This intermediary element serves as a temporary support structure during fabrication that prevents bending and ensures proper spacing, while being simple enough to work with in the fabrication process and ultimately to be removed or retained as part of the final device structure.
