Filed: 2001-08-24
Granted: 2002-09-11
Abstract: The present invention provides a manufacturing method of semiconductor capacitors, which is suitable for use in a dynamic random access memory (DRAM) device. At first, a semiconductor substrate with plugs is provided, and a conducting layer is formed on the semiconductor substrate. Then, impurities are implanted into the conducting layer to form at least one doped region band. After that, the conducting layer on the contact window is defined and etched so as to make the doped region band of the conducting layer sidewall become recessed and the conducting layer sidewall have a non-flat shape. At last, an insulating film and a conducting layer are sequentially formed on the conducting layer to form a semiconductor substrate. Thus, by increasing the surface area of the bottom electrode for the semiconductor capacitor, the capacitance value is increased.

Title: Method for producing an embossing roller from silicone rubber for the continuous embossing of the surface of a thermoplastic film
Inventor: MAKER MICHAEL
IPC: B29K9/00
Filed: 2002-02-20
Granted: 2003-01-21
Abstract: The invention relates to a method for producing an embossing roller from silicone rubber for the continuous embossing of the surface of a thermoplastic film, with the embossing surface having a negative form of a surface structure to be embossed, in particular a grain. First an auxiliary roller is produced which is made of plastic, at least in the region of its circumferential surface. A laser beam is directed onto the smooth circumferential surface in such a way that said laser beam moves relative to the circumferential surface. In addition, the laser beam is controlled so as to be congruent with the particular site on the surface structure of a real pattern or of an imaginary pattern which is present in the form of data, in such a way that the surface structure of the pattern is created as a positive form in the circumferential surface. A layer of silicone rubber of uniform thickness is poured or spread onto this circumferential surface of the auxiliary roller and vulcanized to produce an embossing matrix which is pulled off the circumferential surface, turned inside out, and adhered to a circumferential surface of an embossing roller, with the negatively structured embossing surface facing outward. The method enables embossing matrices to be created several times after a one-time structuring of the surface of an auxiliary roller, using a simple, time-saving, and economical casting process.

Title: Method for dual-damascene patterning of low-k interconnects using spin-on distributed hardmask
Inventor: FORNOF ANN RHEA-HELENE
IPC: H01L21/3205
Filed: 2002-02-22
Granted: 2005-10-11
Abstract: A cost effective and simple method of patterning interconnect structure is provided in which spun-on materials are used as the hard mask. The use of spun-on materials for the hard mask ensures that the process is carried out in a single tool and it permits the use of a single curing step which is not typically employed in prior art patterning processes wherein CVD hard masks are employed. The effective dielectric constant of the resultant structure is not significantly increased since the use of spin coating allows for selection of a polish stop layer (formed on a surface of a low-k dielectric) that has substantially the same dielectric constant as the underlying dielectric. In the present invention, the hard mask employed includes at least two spun-on dielectric materials that have different each other.
