    摘要: An FET transistor has a gate disposed between a source and a drain; a gate dielectric layer disposed underneath the gate; and a spacer on a side of the gate. The gate dielectric layer is conventional oxide and the spacer has a reduced dielectric constant (k). The reduced dielectric constant (k) may be less than 3.85, or it may be less than 7.0 (˜nitride), but greater than 3.85 (˜oxide). Preferably, the spacer comprises a material which can be etched selectively to the gate dielectric layer. The spacer may be porous, and a thin layer is deposited on the porous spacer to prevent moisture absorption. The spacer may comprise a material selected from the group consisting of Black Diamond, Coral, TERA and Blok type materials. Pores may be formed in the spacer material by exposing the spacers to an oxygen plasma.

A provided structure includes: a semiconductor substrate, a transistor on the semiconductor substrate, N interconnect layers on the semiconductor substrate, and a temporary filling region within the N layers. N is at least 2. The temporary filling region is heated at a high temperature sufficiently high to result in the temporary filling material being replaced by a cooling pipes system that does not include any solid or liquid material. A first portion and a second portion of the cooling pipes system are each in direct physical contact with a surrounding ambient at a first interface and a second interface respectively such that a first direction perpendicular to the first interface is perpendicular to a second direction perpendicular to the second interface. A totality of interfaces between the cooling pipes system and the ambient consists of the first interface and the second interface.
