    Abstract: The present invention provides a method of fabricating a semiconductor structure. Firstly, a substrate is provided, a dense region and an isolation region are defined, next, a first dielectric layer is formed on the dense region and the isolation region, and then a plurality of first recesses are formed in the first dielectric layer within the dense region, and a second recess is formed in the first dielectric layer within the isolation region, wherein the width of the second recess is greater than three times of the width of each first recess. Afterwards, a second dielectric layer is then filled in each first recess and the second recess, wherein a top surface of the second dielectric layer within the isolation region is higher than a top surface of the second dielectric layer within the dense region. Next, an etching back process is performed, to remove the second dielectric layer.

    Abstract: A static random access memory unit cell layout structure is disclosed, in which a slot contact is disposed on one active area and another one across from the one. A static random access memory unit cell structure and a method of fabricating the same are also disclosed, in which, a slot contact is disposed on drains of a pull-up transistor and a pull-down transistor, and a metal-zero interconnect is disposed on the slot contact and a gate line of another pull-up transistor. Accordingly, there is not an intersection of vertical and horizontal metal-zero interconnects, and there is no place suffering from twice etching. Leakage junction due to stitch recess can be avoided.

    Abstract: A method of performing an etching process is provided. A substrate is provided, wherein a first region and a second region are defined on the substrate, and an overlapping region of the first region and the second region is defined as a third region. A tri-layer structure comprising an organic layer, a bottom anti-reflection coating (BARC), and a photoresist layer is formed on the substrate. The photoresist layer and the BARC in the second region are removed. An etching process is performed to remove the organic layer in the second region by using the BARC and/or the photoresist layer as a mask, wherein the etching process uses an etchant comprises CO2.
