Abstract: 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).

Abstract: A metal tray has its inner and outer surfaces coated with a plastic material. Within the tray is a first susceptor unit which includes a layer of corrugated paperboard composed of A-flutes secured to the underside of a substrate having a metallized foil secured to its upper side. A food item to be heated is supported on the first susceptor unit. A second susceptor unit overlies the food item, the second susceptor unit having a downturned flange inserted between one side of the tray and one side of the food item.

Abstract: 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.

Abstract: 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.
