    摘要： A monolithic integrated circuit and method includes a substrate, a plurality of semiconductor device layers monolithically integrated on the substrate, and a metal wiring layer with vias interconnecting the plurality of semiconductor device layers. The semiconductor device layers are devoid of bonding or joining interface with the substrate. A method of fabricating a monolithic integrated circuit using a single substrate, includes fabricating semiconductor devices on a substrate, fabricating at least one metal wiring layer on the semiconductor devices, forming at least one dielectric layer in integral contact with the at least one metal wiring layer, forming contact openings through the at least one dielectric layer to expose regions of the at least one metal wiring layer, integrally forming, from the substrate, a second semiconductor layer on the dielectric layer, and in contact with the at least one metal wiring layer through the contact openings, and forming a plurality of non-linear semiconductor devices in said second semiconductor layer.

    摘要： Often used to reduce the RC delay in integrated circuits are dielectric films of porous organosilicates which have a silica like backbone with alkyl or aryl groups (to add hydrophobicity to the materials and create free volume) attached directly to the Si atoms in the network. Si—R bonds rarely survive an exposure to plasmas or chemical treatments commonly used in processing; this is especially the case in materials with an open cell pore structure. When Si—R bonds are broken, the materials lose hydrophobicity, due to formation of hydrophilic silanols and low dielectric constant is compromised. A method by which the hydrophobicity of the materials is recovered using a novel class of silylation agents which may have the general formula (R2N)XSiR′Y where X and Y are integers from 1 to 3 and 3 to 1 respectively, and where R and R′ are selected from the group of hydrogen, alkyl, aryl, allyl and a vinyl moiety. Mechanical strength of porous organosilicates is also improved as a result of the silylation treatment.
