Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a membrane comprising micropassages made from a porous material, by using a chemical mechanical polishing method. SOLUTION: A surface of a support substrate (2) comprising through-micropassages (1) is moved and brought into contact with a pad (4) and with an aqueous solution comprising a plurality of particles (5) in a suspension state. Pressure perpendicular to the plane of the support substrate (2), between the pad (4) and the surface of the support substrate (2) is applied, so as to give relative movement in a direction parallel to the plane of the support substrate between the pad (4) and the surface. At least one particle (5) is thus introduced in each microgap (1) to form a porous material. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
Un circuit électronique intégré comprend une portion de couche mince à base d'oxyde d'hafnium (1). Selon l'invention, cette portion contient en outre des atomes de magnésium, sous forme d'un oxyde mixte d'hafnium et de magnésium. Une telle portion présente une permittivité diélectrique élevée et un courant de fuite très faible. Elle est particulièrement adaptée pour former une partie d'une couche d'isolation de grille d'un transistor MOS ou une partie d'un diélectrique de condensateur MIM.

The present invention provides an improved method of forming air cavities to overcome IC via-misalignment issues. The method of forming air cavity trenches in-between metal lines of an integrated circuit includes the steps of partially removing (42) an intertrack dielectric deposited on an interconnect structure surface to control the height between the top surface of a metal line of the interconnect surface and the surface of the intertrack dielectric; depositing (44) a dielectric liner on the interconnect surface; removing (46) at least part of the dielectric liner on the interconnect surface; successively repeating (48) the deposition of the dielectric liner and the removal of the dielectric liner on the interconnect surface in so far as the interconnect surface is sufficiently protected by a remaining dielectric liner for forming of the plurality of air cavity trenches; and forming (50) at least one air cavity trench in-between the metal lines by etching the intertrack dielectric material.
