Abstract: A substantially rectangular-section casting conduit of an ingot mold, for continuous casting of molten metal, is divided into two portions; a first portion has a variable inner section, by having rounded inner edges with a radius of curvature decreasing gradually in the flow direction of the molten metal along the conduit; the second portion is consecutive with the first portion, and has a constant inner section with rounded inner edges of a predetermined optimum radius of curvature for subsequent rolling operations. The design of the first portion of the casting conduit prevents the metal, as it cools and contracts through the conduit, from detaching from the walls, and in particular from the edges, of the mold, thus enabling an increase in casting speed with no fall in product quality.

Abstract: Improved targets for use in DC_magnetron sputtering of aluminum or like metals are disclosed for forming metallization films having low defect densities. Methods for manufacturing and using such targets are also disclosed. Conductivity anomalies such as those composed of metal oxide inclusions can induce arcing between the target surface and the plasma.

Reducing the content of conductivity anomalies and strengthening the to-be-deposited material is seen to reduce production of such splats or blobs. Other splat limiting steps include smooth finishing of the target surface and low-stress ramp up of the plasma.

The plastic strips, which have widths and heights equal to the desired widths and depths of the cooling channels, are placed on the backup member at the intended locations of the cooling channels. Copper is plated onto the backup member to the height of the strips which are then removed to form the cooling channels.
