    Abstract: Various embodiments of the invention present techniques for forming structures (e.g. HARMS-type structures) via an electrochemical extrusion (ELEX TM ) process. Preferred embodiments perform the extrusion processes via depositions through anodeless conformable contact masks that are initially pressed against substrates that are then progressively pulled away or separated as the depositions thicken. A pattern of deposition may vary over the course of deposition by including more complex relative motion between the mask and the substrate elements. Such complex motion may include rotational components or translational motions having components that are not parallel to an axis of separation. More complex structures may be formed by combining the ELEX TM process with the selective deposition, blanket deposition, planarization, etching, and multi-layer operations of EFAB TM .

    Abstract translation: 本发明的各种实施方案提供了通过电化学挤出(ELEX TM)方法形成结构(例如HARMS型结构)的技术。 优选的实施方案通过沉积通过无阳极适应的接触掩模进行挤出过程,其最初被压在基底上,然后随着沉积增厚逐渐拉开或分离。 沉积图案可以通过在掩模和衬底元件之间包括更复杂的相对运动而在沉积过程中变化。 这种复杂运动可以包括旋转分量或具有不与分离轴平行的分量的平移运动。 可以通过将ELEX TM工艺与EFAB TM的选择性沉积,覆盖沉积,平坦化,蚀刻和多层操作组合来形成更复杂的结构。
