摘要： A process is described for the fabrication of submicton interconnect structures for integrated circuit chips. Void-free and seamless conductors are obtained by electroplating Cu from baths that contain additives and are conventionally used to deposit level, bright, ductile, and low-stress Cu metal. The capability of this method to superfill features without leaving voids or seams is unique and superior to that of other deposition approaches. The electromigration resistance of structures making use of CU electroplated in this manner is superior to the electromigration resistance of AlCu structures or structures fabricated using Cu deposited by methods other than electroplating.

摘要： A low-k dielectric for use as an interlayer for an interconnect structure is provided. The dielectric of the present invention is an alkaline boron silicate glass which when formulated in certain compositional ranges can undergo spinodal decomposition when processed using certain thermal profiles. Spinodal decomposition is a chemical and physical separation of the silicate glass into a distinct interpenetrating microstructure which contains a substantially pure silicon dioxide network and a boron-rich network. The dimension (i.e., scale), and the amount of separation can be controlled through compositional and thermal control during the processing of the silicate glass.

摘要： Improved mechanical and adhesive strength and resistance to breakage of copper integrated circuit interconnections is obtained by forming a copper alloy in a copper via/wiring connection in an integrated circuit while minimizing adverse electrical effects of the alloy by confining the alloy to an interfacial region of said via/wiring connection and not elsewhere by a barrier which reduces or substantially eliminates the thickness of alloy in the conduction path. The alloy location and composition are further stabilized by reaction of all available alloying material with copper, copper alloys or other metals and their alloys.

摘要： A method for far back end of line (FBEOL) semiconductor device formation includes forming a terminal copper pad in an upper level of a semiconductor wafer, forming an insulating stack over the terminal copper pad, and patterning and opening a terminal via within a portion of the insulating stack so as to leave a bottom cap layer of the insulating stack protecting the terminal copper pad. An organic passivation layer is formed and patterned over the top of the insulating stack, and the bottom cap layer over the terminal copper pad is removed. A ball limiting metallurgy (BLM) stack is deposited over the organic passivation layer and terminal copper pad, and a solder ball connection is formed on a patterned portion of the BLM stack.

摘要： A method of selectively altering material properties of a substrate in one region while making a different alteration of material properties in an adjoining region is provided. The method includes selectively masking a first portion of the substrate during a first exposure and selectively masking a second portion of the substrate during a second exposure. Additionally, a mask may be formed having more than one thickness where each thickness will selectively reduce the amount of energy from a blanket exposure of the substrate thereby allowing a substrate to receive different levels of energy dosage in a single blanket exposure.
