摘要： A method for forming dual damascene metallic structure that utilizes the formation of a protective photoresist layer at the bottom of a vertical window to prevent damages to a device region in the substrate when subsequent etching operation is carried out to form a horizontal trench pattern. The protective photoresist layer at the bottom of the vertical window is formed by irradiating the photoresist layer with a dose of radiation having energy level insufficient to chemically dissociate the photoactive molecules of the photoresist layer near the bottom of the vertical window.

摘要： A system and method to compensate for the proximity effects in the imaging of patterns in a photolithography process. A light exposure of a photoresist layer is effectuated in predetermined patterns through an exposure mask having light-transmissive openings in correspondence to the predetermined patterns. The exposure mask has areas densely populated with the light-transmissive openings and areas sparsely populated with the light-transmissive openings. Light is attenuated through the densely populated light-transmissive openings by a different amount than through the sparsely populated light-transmissive openings.

摘要： A method for characterizing line width roughness of printed features is provided. A wafer having thereon a plurality of gratings formed within a test key region is prepared. The wafer is transferred to a spectroscopic ellipsometry tool having a light source, a detector and a computer. A polarized light beam emanated from the light source is directed onto the gratings. Spectrum data of reflected light is measured and recorded. The spectrum data is compared to a library linked to the computer in real time. The library contains a plurality of contact-hole model based spectra created by incorporating parameter values that describes the line width roughness. The spectrum data is matched with the contact-hole model based spectra, thereby determining the parameter values.

摘要： This invention provides a method of forming a multi-layer photo mask on a photo mask substrate. A first transparent layer comprising at least one vertical side wall is formed on at least one predetermined area of the photo mask substrate. A first opaque spacer is formed around the vertical side wall of the first transparent layer, and the top side of the first spacer is approximately leveled off with the upper surface of the first transparent layer. An external transparent layer is formed on the photo mask substrate and outside the predetermined area, and the upper surface of the external transparent layer is leveled off with that of the first transparent layer. So the first transparent layer and the external transparent layer form a first photo mask layer. A second transparent layer comprising at least one vertical side wall is formed on at least one predetermined area of the first photo mask layer. A second opaque spacer is formed around the vertical side wall of the second transparent layer, and the top side of the second spacer is approximately leveled off with the upper surface of the second transparent layer.

摘要： This invention provides a method of forming a node contact with self-alignment on a semiconductor wafer. The wafer comprises a substrate, a dielectric layer, and a first and a second bit lines. A first side wall of the first bit line is adjacent to a second side wall of the second bit line and comprises a first region and two second regions adjacent to the first region. The distance between the first region and the second side wall is greater than a predetermined value and the distance between the two second regions and the second side wall is less than the predetermined value. A second insulating layer is formed on the dielectric layer and two bit lines to form a groove over the gap between the first region and the second side wall. A first anisotropic etching is performed to extend the bottom of the groove down to the dielectric layer. The remaining second insulating layer around the groove forms a spacer, and the remaining second insulating layer in the gaps between the two second regions and the second side wall still completely covers the surface of the two gaps. A second anisotropic etching process is performed to remove the dielectric layer at the bottom of the groove in a vertical direction down to the substrate so as to form the node contact.

摘要： A method for fabricating an alternating phase shifting mask includes a transparent substrate, a number of oblique layers formed on the transparent substrate, and a number of embedded phase shift layers inside the transparent substrate. Then, a photolithography process is applied to form a photoresist layer on the transparent substrate corresponding to a desired pattern and, therefore, exposing a portion of the transparent substrate. Then, an ion implantation process utilizing the photoresist layer as a mask is applied to form the embedded phase shift layers and the photoresist layer is removed after ion implantation. The embedded phase shift layers are formed in alternating positions in the transparent portion between the oblique layers.
