    Abstract: A method of manufacturing a LIGA mold by backside exposure includes the steps of: disposing a mask layer at a side of a first substrate, wherein the first substrate is transparent to a predetermined light source and has a front side and a backside; forming a photoresist layer on the front side of the first substrate; providing the predetermined light source to illuminate the backside of the first substrate so as to expose the photoresist layer to form an exposed portion and an unexposed portion; removing the unexposed portion to form a patterned structure on the photoresist layer; forming a metal layer on the patterned structure of the photoresist layer and the first substrate; and removing the photoresist layer and the first substrate to remain the metal layer as the LIGA mold, which is good in a de-molding procedure of a hot embossing process.

    Abstract: An improved and new process for fabricating dual damascene copper, in which trench/via liner removal from porous low-k dielectric, is performed using a new RIE chemistry of CF4/H2, to etch SiN and SiC liners. Prior to the new process, convention liner etching produced the following deleterious results: a) Cu re-deposition by sputtering, b) polymer deposits, and c) surface roughening of the porous low-k IMD dielectric. Process details are: CF4/H2 based with approximate gas flow ratios of greater than 10 to 1, hydrogen to carbon tetra-fluoride. A nominal flow ratio of 300 to 20, hydrogen to carbon tetra-fluoride, or 15 to 1, was developed.

    Abstract: A method of forming 3D micro structures with high aspect ratios includes the steps of: disposing a mask, which has a plurality of through holes having at least two different sizes, on a substrate to expose the substrate through the through holes; forming a negative photoresist layer on the mask and the substrate; providing a light source to illuminate the negative photoresist layer through the substrate and the through holes of the mask so as to form a plurality of exposed portions and an unexposed portion; and removing the unexposed portion and leaving the exposed portions to form a plurality of pillars each having a bottom portion contacting the substrate and a top portion opposite to the bottom portion. A top area of the top portion is slightly smaller than a bottom area of the bottom portion, and the pillars are allowed to have at least two different heights.

    Abstract: A method of forming a dual damascene opening comprising the following steps. A structure having an overlying exposed conductive layer formed thereover is provided. A dielectric layer is formed over the exposed conductive layer. An anti-reflective coating layer is formed over the dielectric layer. The anti-reflective layer and the dielectric layer are etched using a via opening process to form an initial via exposing a portion of the conductive layer. A protective film portion is formed over at least the exposed portion of the conductive layer. The anti-reflective coating layer and the dielectric layer are patterned to reduce the initial via to a reduced via and to form a trench opening substantially centered over the reduced via. The trench opening and the reduced via comprising the dual damascene opening.
