Abstract:
Sealing a via using a soventless, low viscosity, high temperature stable polymer or a high solids content polymer solution of low viscosity, where the polymeric material is impregnated within the via (100) at an elevated temperature, A supply chamber (630) is introduced to administer the polymeric material at an elevated temperature, typically at a temperature high enough to liquefy the polymeric material. The polymeric material is introduced through heated supply lines under force from a pump, piston, or a vacuum held within said supply chamber.

PROBLEM TO BE SOLVED: To provide a structure which realizes high performance interconnection including copper wiring and an insulator having an extremely low dielectric constant (k). SOLUTION: In this structure, wiring is supported by a low-k dielectric material having relatively high durability, such as SiLk(R) or SiO 2 , and then the remaining spaces in the structure are filled with a gap filling dielectric material that has an extremely low-k and a small hardness. Accordingly, in the structure, durable layers for obtaining the strength are bonded with an extremely low-k dielectric material for achieving electric performance of the interconnection. As a result, damages to and an increase in dielectric constant of the extremely low-k dielectric material caused during the manufacturing process are avoided, and delamination in the structure during the metal chemical mechanical polishing processes is prevented. Further, photoresist poisoning troubles caused by interaction with the extremely low-k dielectric material can be removed. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To enable a first film to align when a second film on a plane by adding triethanolamine to a polishing slurry, which reacts with the first film and with the second film of a second material under a predetermined part of the first film, to increase the reactivity with respect to the first film and by exposing the second film by interrupting the polishing, when the first film is removed completely. SOLUTION: In order to control the polishing speed of the material of a composite material substrate, the substrate having a first film formed of a first material and a second film formed of a second material lying under a predetermined part of the first film is chemical-mechanical polished using a slurry reacting, with the first and second films so as to remove the most part of the first film. Then, adequate amount of triethanolamine is added to the slurry for increasing the reactivity of the slurry with the first film and chemical- mechanical polishing is carried out. Thereupon, the residual part of the first film is removed, and if the polishing is interrupted when the first film on the part under which second film lies is removed completely, a specified part is exposed so that the first film is aligned with the second film on a plane.
Abstract:
PROBLEM TO BE SOLVED: To provide a structure and a manufacturing method of a microelectric mechanical switch (MEMS) device provided with a self-alignment spacer or a bump. SOLUTION: The spacers arranged having the optimum size so as to make to the minimum a problem caused by stiction by functioning as restricting mechanism concerning the switch are designed. The spacers are manufactured by using the typically standard semi-conductor technology used for manufacturing a CMOS device. This method to manufacture these spacers does not need an additional deposition, excessive lithography process, and an additional etching. COPYRIGHT: (C)2004,JPO
