摘要:
The invention provides a method for regenerating viable and fertile Citrus plants by tissue culture from explants of field-grown mature trees, said method comprising the steps of incubating the explant in agarified media to develop axillary buds, subculturing the explant alongwith sprouted axillary buds in agarified media, excising the meristem domes along with leaf primordia in another medium to generate shoots, subculturing the meristem-regenerated shoots on filter paper bridge employing a liquid medium in order to obtain healthy shoots of an average length of about 1.5 cm without intervening callusing within a period of 20-25 days, proliferating the meristem-regenerated shoots in agarified media to obtain well-developed shoots, rooting the isolated well-developed shoots in agarified media, transferring the freshly developed roots of Citrus sinensis to a different medium while allowing the shoots of C. aurantifolia to grow in the same medium for about 15 days to develop tap roots, hardening the rooted shoots ex vitro in a liquid medium, and allowing the shoots to grow in the same medium under incubation conditions, transferring the hardened shoot meristem-raised plants to soilrite in pro-trays for ex vitro growth for about 7 days to ensure 95% to 100% survival of the shoot meristem raised Citrus plants.
摘要:
A method of forming a dual damascene metal interconnect for a semiconductor device. The method includes forming a layer of low-k dielectric, forming vias through the low-k dielectric layer, depositing a sacrificial layer, forming trenches through the sacrificial layer, filling the vias and trenches with metal, removing the sacrificial layer, then depositing an extremely low-k dielectric layer to fill between the trenches. The method allows the formation of an extremely low-k dielectric layer for the second level of the dual damascene structure while avoiding damage to that layer by such processes as trench etching and trench metal deposition. The method has the additional advantage of avoiding an etch stop layer between the via level dielectric and the trench level dielectric.

摘要:
The present disclosure provides a method for fabricating an integrated circuit. The method includes forming an energy removable film (ERF) on a substrate; forming a first dielectric layer on the ERF; patterning the ERF and first dielectric layer to form a trench in the ERF and the first dielectric layer; filling a conductive material in the trench; forming a ceiling layer on the first dielectric layer and conductive material filled in the trench; and applying energy to the ERF to form air gaps in the ERF after the forming of the ceiling layer.
