Publication number: 20040004267Abstract: Disclosed is a programmable element including a semiconductor material doped with a dopant that alters the resistance of the element when exposed to actinic radiation. Rather than producing a mechanical deformation, the radiation rearranges the bonding configuration of the dopant in the element, allowing it to be placed on a chip in close proximity to other device structures without risking damage to those structures. After formation, the programmable element is subjected to a laser anneal process in which the dopant is electrically activated. The activation process allows the dopant to donate a charge carrier to the crystal structure. Rapid cooling following laser anneal preserves the desired bonding configuration of the dopant produced in the programmable element. Laser anneals have been shown to reduce the resistivity of a programmable element by at least a factor of two.Type: ApplicationFiled: July 2, 2002Publication date: January 8, 2004Applicant: International Business Machines CorporationInventors: Patricia S.

Publication number: 20040004285Abstract: Typically, primary electrical connection between a semiconductor chip and an external solder ball contact on a Ball Grid or Chip Scale Package is by way of a via extending through a dielectric substrate. The aspect ratio between via diameter and depth is critical for reliable and high yield solder ball attachment during printed circuit board assembly. Excellent ball adherence and reliability of BGA solder ball contacts is achieved through controlling the aspect ratio of the substrate vias by partially plating a solid solderable conductor core in each via. An improved via structure is disclosed wherein the depth of the viva is reduced without the negative effects of alternate methods, such as thinner substrates, or wider vias.Type: ApplicationFiled: June 26, 2003Publication date: January 8, 2004Inventors: Johnny Cheng, Joyce Hsu
