  • Patent number: 8349729
    Abstract: Each of a first substrate and a second substrate includes a surface having a diffusion resistant dielectric material such as silicon nitride. Recessed regions are formed in the diffusion resistant dielectric material and filled with a bondable dielectric material. The patterns of the metal pads and bondable dielectric material portions in the first and second substrates can have a mirror symmetry. The first and second substrates are brought into physical contact and bonded employing contacts between metal pads and contacts between the bondable dielectric material portions. Through-substrate-via (TSV) structures are formed through bonded dielectric material portions. The interface between each pair of bonded dielectric material portions located around a TSV structure is encapsulated by two diffusion resistant dielectric material layers so that diffusion of metal at a bonding interface is contained within each pair of bonded dielectric material portions.

  • Patent number: 8227307
    Abstract: The present invention provides a method of forming a threshold voltage adjusted gate stack in which an external acid diffusion process is employed for selectively removing a portion of a threshold voltage adjusting layer from one device region of a semiconductor substrate. The external acid diffusion process utilizes an acid polymer which when baked exhibits an increase in acid concentration which can diffuse into an underlying exposed portion of a threshold voltage adjusting layer. The diffused acid reacts with the exposed portion of the threshold voltage adjusting layer providing an acid reacted layer that can be selectively removed as compared to a laterally adjacent portion of the threshold voltage adjusting layer that is not exposed to the diffused acid.

  • Patent number: 8227870
    Abstract: A method and structure to scale metal gate height in high-k/metal gate transistors. A method includes forming a dummy gate and at least one polysilicon feature, all of which are formed from a same polysilicon layer and wherein the dummy gate is formed over a gate metal layer associated with a transistor. The method also includes selectively removing the dummy gate while protecting the at least one polysilicon feature. The method further includes forming a gate contact on the gate metal layer to thereby form a metal gate having a height that is less than half a height of the at least one polysilicon feature.
