  • Patent number: 6117367
    Abstract: Metal pastes used in the fabrication of multilayer ceramic (MLC) substrates used in semiconductor devices. The pastes reduce substrate defects, such as via bulge and camber. The pastes are comprised of a metal having high conductivity, frit which includes glass, an organic binder, and a solvent, optionally with a surfactant.

  • Patent number: 6004624
    Abstract: Electronic packages made with a high area percent coverage of blanket metal may be prone to certain kinds of ceramic defects. In aluminum nitride, these defects may be related to decomposition of the liquid sintering aid. In this experiment, unique additions to the metallization prevented the formation of certain ceramic defects. Our approach involves a unique composition used in an existing process.

  • Patent number: 5911945
    Abstract: A single furnace loading cycle method for sintering at least one product comprises placing at least one product into a ventable/sealable box, and placing the box within the furnace. The box is vented inside the furnace at a first temperature range and the product is sealed inside the box in a second temperature range, wherein the second temperature range is higher than the first temperature range. The box includes a closeable top cover and a control means that comprises a first set of collapsible spacers which hold open the cover at temperatures below the first temperature range and collapse to lower the cover into sealing engagement with the box at temperatures above the first temperature range. The box further comprises a substrate to be sintered with a lower and an upper setter on opposite sides of the substrate.

  • Patent number: 5755570
    Abstract: A single furnace loading cycle technique and a ventable sintering box therefor are disclosed for the sintering of products, such as, ceramic substrates. The sintering box includes a closeable cover which is held open by collapsible or deformable or sensitive spacers in a first furnace temperature range. The sensitive spacers collapse or deform in a higher temperature range to seal closed the box and the substrates therein. Thus, volatile agents within the substrates are permitted to escape in the first temperature range but are prevented from escaping in the higher temperature range.Provision also is made using additional sensitive spacers for applying a weight upon the substrates when in the higher temperature range due to the collapse or deformation of the sensitive spacers.

  • Patent number: 5753162
    Abstract: A single furnace loading cycle method for sintering at least one product. The method comprises the steps of placing at least one product into a ventable/sealable box, which box is placed inside a furnace. The box is vented inside the furnace at a first temperature range, and then the box is sealed with the at least one product inside the box in a second temperature range, wherein the second temperature range is higher than the first temperature range, and wherein the step of sealing occurs after the step of venting without removing the box from the furnace.

Additional spacers may be used for applying weight upon the substrates at the higher temperature range.

  • Patent number: 5552232
    Abstract: Disclosed is an aluminum nitride body having graded metallurgy and a method for making such a body. The aluminum nitride body has at least one via and includes a first layer in direct contact with the aluminum nitride body and a second layer in direct contact with, and that completely encapsulates, the first layer. The first layer includes 30 to 60 volume percent aluminum nitride and 40 to 70 volume percent tungsten and/or molybdenum while the second layer includes 90 to 100 volume percent of tungsten and/or molybdenum and 0 to 10 volume percent of aluminum nitride.

  • Patent number: 5509556
    Abstract: A process of forming an aperture in a metallic sheet including the steps of:a) defining at least one feature in a sheet of metallic material;b) laser drilling the at least one feature but not entirely removing it from the metallic sheet, the at least one feature being partially filled by metallic material which has melted and resolidified; and thenc) chemically etching the metallic sheet and the melted and resolidified metallic material wherein the etchant attacks and at least partially dissolves the melted and resolidified metallic material, weakening the bond of the melted and resolidified metallic material to the metallic sheet.
