Patent number: 9766170Abstract: A method and computer product program for determining Young's modulus. The method includes placing a probe in contact with a surface of a material on a substrate and, with an initial force of 800 nano newtons or less; determining the location of the surface relative to an initial indentation depth for the initial force; increasing the force on the probe from the initial force to a maximum force greater than the initial force to generate a load curve; decreasing the force on the probe from the maximum force to the initial force to generate an unload curve, the maximum force selected such that the unload curve is independent of the presence of the substrate; and using the unload curve, determining a relationship between (i) the reduced modulus of the sample material and (ii) the ratio of probe penetration depth and the thickness of the layer.Type: GrantFiled: January 28, 2015Date of Patent: September 19, 2017Assignee: International Business Machines CorporationInventors: Geraud J.

Patent number: 9214335Abstract: The present invention describes a process to modify a top portion of a porous ultra low-k (ULK) material in order to maximize porosity filling with a filling material that initially displayed low compatibility with the ULK material. Surface modification is achieved by a plasma treatment, enhancing the compatibility between the ULK surface and the filling material. The invention obtains high filling levels with minimum modification to the ULK material, as only a thin top portion is modified without significant pore sealing.Type: GrantFiled: April 24, 2014Date of Patent: December 15, 2015Assignee: International Business Machines CorporationInventors: Robert L.

Patent number: 8828489Abstract: Porous films are homogeneously and partially (but not completely) filled. A composition (that includes a polymer) is brought into contact with a planar film that has interconnected pores throughout the film.
