A semiconductor device is fabricated with energy based process(es) that alter etch rates for dielectric layers within damascene processes. A first interconnect layer is formed over a semiconductor body. A first dielectric layer is formed over the first interconnect layer. An etch rate of the first dielectric layer is altered. A second dielectric layer is formed on the first dielectric layer. An etch rate of the second dielectric layer is then altered. A trench etch is performed to form a trench cavity within the second dielectric layer. A via etch is performed to form a via cavity within the first dielectric layer. The cavities are filled with conductive material and then planarized to remove excess fill material.

A method of manufacturing a semiconductor device is presented. In one aspect, the method comprises forming conductive and ferroelectric material layers on a semiconductor substrate. The material layers are patterned to form electrodes and a ferroelectric layer of a ferroelectric capacitor, wherein a conductive noble metal-containing polymer is generated on sidewalls of the ferroelectric capacitor. The method also comprises converting the conductive noble metal-containing polymer into a non-conducting metal oxide. Converting includes forming a water-soluble metal salt from the conductive noble metal-containing polymer and reacting the water-soluble metal salt with an acqueous acidic solution to form a metal hydroxide. Converting also includes oxidizing the metal hydroxide to form the non-conducting metal oxide.

摘要:
Plasma treating a low-k dielectric layer (104) using an oxidation reaction (e.g., O2) to improve patterning. Resist poisoning occurs due to an interaction between low-k films (104), such as OSG, and DUV resist (130, 132). The plasma treatment is performed to either pretreat a low-k dielectric (104) before forming the pattern (130, 132), during a rework of the pattern (130, 132), or between via and trench patterning to reduce resist poisoning.

The present invention facilitates semiconductor fabrication by providing methods of fabrication that selectively apply strain to multiple regions of a semiconductor device. A semiconductor device having one or more regions is provided (102). A strain inducing liner is formed over the semiconductor device (104). A selection mechanism, such as a layer of photoresist or UV reflective coating is applied to the semiconductor device to select a region (106). The selected region is treated with a stress altering treatment that alters a type and/or magnitude of stress produced by the selected region (108).
