  • Patent number: 7456098
    Abstract: Stacked via pillars, such as metal via pillars, are provided at different and designated locations in IC chips to support the chip structure during processing and any related processing stresses such as thermal and mechanical stresses. These stacked via pillars connect and extend from a base substrate of the strip to a top oxide cap of the chip. The primary purpose of the stacked via pillars is to hold the chip structure together to accommodate any radial deformations and also to relieve any stress, thermal and/or mechanical, build-tip during processing or reliability testing. The stacked via pillars are generally not electrically connected to any active lines or vias, however in some embodiments the stacked via pillars can provide an additional function of providing an electrical connection in the chip.

  • Patent number: 6750109
    Abstract: A semiconductor chip includes a semiconductor substrate having a rectifying contact diffusion and a non-rectifying contact diffusion. A halo diffusion is adjacent the rectifying contact diffusion and no halo diffusion is adjacent the non-rectifying contact diffusion. The rectifying contact diffusion can be a source/drain diffusion of an FET to improve resistance to punch-through. The non-rectifying contact diffusion may be an FET body contact, a lateral diode contact, or a resistor or capacitor contact. Avoiding a halo for non-rectifying contacts reduces series resistance and improves device characteristics. In another embodiment on a chip having devices with halos adjacent diffusions, no halo diffusion is adjacent a rectifying contact diffusion of a lateral diode, significantly improving ideality of the diode and increasing breakdown voltage.

  • Patent number: 6475555
    Abstract: A process wherein a low viscosity, metal-containing paste is screened onto a ceramic greensheet and then sets up to increase its viscosity. In one method, the low viscosity is caused by excess solvent which is then blotted or otherwise removed so that the viscosity of the paste is increased. In an alternative method, the low viscosity paste contains a cross-linking agent which causes the paste to increase its viscosity after screening.

  • Patent number: 5951917
    Abstract: Deformation of vias and shorting between vias during screening of conductive paste onto greensheets wider than 185 mm is avoided by a concentration of thixotropic agent in the conductive paste formulation to a concentration which raises the thixotropic index of the paste to within 5% to 25% of the maximum achievable thixotropic index for the organic vehicle in the paste. For a paste containing molybdenum powder in which the organic vehicle is a mixture of ethyl cellulose, texanol and oleoyl sarcosine, this criterion corresponds to a concentration of glycerl tri(-12-hydroxystearate) in the range of 1.4% to 1.8% by weight.
