Patent ID: 8618183

Claim:
A method comprising: providing a single precursor selected from the group consisting of an alkoxysilane containing one Câ•C double bond into a reactor, wherein said one Câ•C double bond is a built-in porogen; depositing a dielectric film from said single precursor in the presence of at least CO; and removing said built-in porogen from said dielectric film to provide a porous dielectric material comprising a first phase and a second phase comprised of pores, wherein said pores have a diameter of about 5 nm or less, a pore size distribution having a maximum that is less than about 1 nm, a full width at half maximum in the pore size distribution ranging from 1 to 3 nm, and with a fraction less than 0.1 of pores having a pore size of greater than about 1 nm.
