摘要： Methods are provided for fabricating silicon carriers with conductive through-vias that allow high-yield manufacture of silicon carrier with low defect density. In particular, methods are provided which enable fabrication of silicon carries with via diameters such as 1 to 10 microns in diameter for a vertical thickness of less than 10 micrometers to greater than 300 micrometers, which are capable robust to thermal-mechanical stresses during production to significantly minimize the thermal mechanical movement at the via sidewall interface between the silicon, insulator, liner and conductor materials.

摘要： A conductive material is electroplated onto a platable resistive metal barrier layer(s) employing a plating bath optionally comprising a super filling additive and a suppressor, and by changing the current or voltage as a function of the area of plated metal. A structure is also provided that comprises a substrate, a platable metal barrier layer(s) located on the substrate and a relatively continuous uniform electroplated layer of a conductive material located on the platable resistive metal barrier layer.

摘要： The invention provides a method of forming a wiring layer in an integrated circuit structure that forms an organic insulator, patterns the insulator, deposits a liner on the insulator, and exposes the structure to a plasma to form pores in the insulator in regions next to the liner. The liner is formed thin enough to allow the plasma to pass through the liner and form the pores in the insulator. During the plasma processing, the plasma passes through the liner without affecting the liner. After the plasma processing, additional liner material may be deposited. After this, a conductor is deposited and excess of portions of the conductor are removed from the structure such that the conductor only remains within patterned portions of the insulator. This method produces an integrated circuit structure that has an organic insulator having patterned features, a liner lining the patterned features, and a conductor filling the patterned features. The insulator includes pores along surface areas of the insulator that are in contact with the liner and the pores exist only along the surface areas that are in contact with the liner (the liner is not within the pores).

摘要： Organic addition agents in copper plating baths are monitored by diluting a sample of the bath with sulfuric acid and hydrochloric acid and optionally a cupric salt. The diluting provides a bath having conventional concentrations of cupric ion, sulfuric acid and hydrochloric acid; and adjusted concentrations of the organic addition agents of 1/X of their original values in the sample; where X is the dilution factor. CVS techniques are used to determine concentrations of organic addition agents.
