Abstract: A copper alloy layer is blanket deposited over a low k dielectric layer and in via openings within the low k dielectric layer. The blanket deposited layer is then anisotropically etch to form horizontal interconnects. The interconnects are annealed to form a metal oxide barrier lining. A second low k dielectric layer is then depositing over the horizontal interconnects. Air gaps can be formed between adjacent interconnects to lower parasitic capacitance therebetween.

Abstract: One or more techniques or systems for forming a pattern during semiconductor fabrication are provided herein. In some embodiments, a photo resist (PR) region is patterned and a spacer region is formed above or surrounding at least a portion of the patterned PR region.

In some embodiments, the BCP comprises a first polymer and a second polymer. In some embodiments, the second polymer is removed, thus forming a pattern comprising the first polymer and the spacers. In this manner, a method for forming a pattern during semiconductor fabrication is provided, such that a width of the spacer or the first polymer is controlled.

Abstract: A method for processing time series is disclosed. In the method, the time series is distributed into a plurality of indexes. A statistical method is applied to the data in each index for generating corresponding statistical result. The statistical result is the value with respect to the every index, and also the record with respect to the indexes in the time series. The statistical result for the every index is temporarily buffered. After that, a new input time series is compared with the statistical result for every index so as to select one of the indexes. The new input data is therefore inserted to the selected index. The statistical method is then applied to this selected index again. A new statistical result is generated. The record is updated as referring to the selected index and the new corresponding statistical result.

Abstract: A method and an adjustment device for adaptively adjusting a database structure are provided. The adjustment device is arranged between a client and a database. The client generates a database instruction and transmits the database instruction to the database. The database executes the database instruction and accordingly generates an interpretable execution result to the adjustment device. The adjustment device determines whether the database structure needs to be adjusted. When the database structure needs to be adjusted, the adjustment device adjusts the database structure configured in the database according to the execution result. When the database structure needs not to be adjusted, the adjustment device transmits the execution result back to the client. Accordingly, when the engineer develops an application system, they do not consider whether to redesign the new database structure, thereby the method and the adjustment device can improve the system development efficiency.

Abstract: A method for forming a semiconductor interconnect structure comprises forming a dielectric layer on a substrate and patterning the dielectric layer to form an opening therein. The opening is filled and the dielectric layer is covered with a metal layer having a first etch rate. The metal layer is thereafter planarized so that the metal layer is co-planar with the top of the dielectric layer. The metal layer is annealed to change the first etch rate into a second etch rate, the second etch rate being lower than the first etch rate. A copper-containing layer is formed over the annealed metal layer and the dielectric layer. The copper-containing layer has an etch rate greater than the second etch rate of the annealed metal layer. The copper-containing layer is etched to form interconnect features, wherein the etching stops at the top of the annealed metal layer and does not etch thereunder.

Abstract: Among other things, one or more techniques for forming a low k dielectric around a metal line during an integrated circuit (IC) fabrication process are provided. In an embodiment, a metal line is formed prior to forming a surrounding low k dielectric layer around the metal line. In an embodiment, the metal line is formed by filling a trench space in a skeleton layer with metal. In this embodiment, the skeleton layer is removed to form a dielectric space in a different location than the trench space. The dielectric space is then filled with a low k dielectric material to form a surrounding low k dielectric layer around the metal line. In this manner, damage to the surrounding low k dielectric layer, that would otherwise occur if the surrounding low k dielectric layer was etched, for example, is mitigated.
