A multilayer substrate provides predetermined connections to and between a plurality of integrated circuit chips mounted thereon. A plurality of layers mounted on a surface of a substrate has a plurality of layers comprising a plurality of dielectric layers, a first plurality of metallic layers, and a second plurality of metallic layers. The first plurality of metallic layers has a predetermined pattern for forming the predetermined connections, these being the x-lines and y-lines. Each of the second plurality of metallic layers provides a predetermined voltage level to the integrated circuit chips, and each of the second metallic layers has a screen-like structure. Each of the first and second metallic layers is insulated from the other metallic layers by one of the dielectric layers, except for desired interconnections between the x-lines y-lines, and power layer (or power plane).

A gas distribution system provides a gas to a chamber comprising a feed tube, having a tube-like configuration with an input and an output. The gas supplied to the input escapes via the output, the output being configured to have a first and second slot opening. The first slot opening has a predetermined first length along the length of the feed tube and has a predetermined first width across the length of the feed tube, and the second slot opening has a predetermined second length along the length of the feed tube and has a predetermined second width across the length of the feed tube. The second slot is contiguous with and abuts the first slot, and further the predetermined second width is smaller than the predetermined first width. The first and second slot configuration provides the gas at the output at a predetermined pressure, the predetermined pressure being reduced from an area near the output. A plenum, having a rectangular box-like configuration with a definable predetermined length and also having an opening corresponding in configuration to the output, receives the gas escaping from the output of the feed tube to temporarily contain the gas in a chamber formed by the plenum. The plenum further has a plurality of orifices such that the gas escaping from the orifices provides a predetermined spray pattern of the gas within the chamber along the length of the plenum, the length of the feed tube and the predetermined length of the plenum being parallel to each other.

A squeegee is utilized in a screen process printer for microcircuits and components thereof. The type is one in which the squeegee and a flat stationary screen are mounted with the squeegee movable and in a wiping action makes contact with the screen so as to press a paste through openings of the screen in a predetermined pattern onto an adjacent substrate. The squeegee comprises a cylindrically shaped object of a predetermined length having a surface covering made of a resiliently deformable material. Further, the squeegee has an external cross-sectional geometric pattern such that a first surface is pushed against the paste in the wiping action. A lower edge of the first surface is above the surface of the screen a predetermined distance, and the first surface is at a predetermined fixed angle with the screen thereby causing a spreading action of the paste on the screen surface. The geometric pattern further has a second surface whereby a lower edge of the second surface is in pressure contact with the screen, and further wherein the angle of the second surface to the screen is less than the angle of the first surface to the screen, thereby providing a high hydraulic pressure forcing the paste into the screen openings.
