摘要: A three dimensional non-volatile memory structure includes word lines connected to non-volatile memory cells arranged in blocks. A plurality of word line switches are connected to the word lines and one or more sources of voltage. The word line switches are arranged in groups of X word line switches such that each group of X word line switches is positioned in a line under Y blocks of non-volatile memory cells and has a length that is equal to the width of the Y blocks of non-volatile memory cells. To allow closer placement of word line switches that supply different blocks and support the possible large voltage differences between their transistors, word line switches supplying different blocks are formed over a single active region and separated by an intermediate control gate set to be off.

摘要: A semiconductor structure includes a semiconductor device, an overlying silicon nitride diffusion barrier layer, and an interconnect structure extending through the silicon nitride diffusion barrier layer. The interconnect structure includes a titanium diffusion barrier structure in contact with the silicon nitride diffusion barrier layer to form a continuous hydrogen diffusion barrier structure.

摘要: A three-dimensional memory device includes an alternating stack of insulating layers and electrically conductive layers located over a substrate, memory stack structures vertically extending through the alternating stack, each memory stack structure including a memory film and a vertical semiconductor channel, and a contact well set that includes contact wells extending through a respective upper region of the alternating stack. Each of the contact wells contains first stepped surfaces which have a stepwise descending vertical profile along a first horizontal direction and second stepped surfaces which have a stepwise descending vertical profile along a second horizontal direction which is perpendicular to the first horizontal direction.

摘要: A semiconductor structure, such as a CMOS device, includes a first field effect transistor and a second field effect transistor. The first field effect transistor includes a first composite gate electrode containing a first vertical stack of a p-doped semiconductor gate electrode, a first interfacial dielectric layer, and a first metallic gate electrode. The second field effect transistor includes a second composite gate electrode containing a second vertical stack that includes an n-doped semiconductor gate electrode and a second metallic gate electrode. A second interfacial dielectric layer having a second thickness that is thinner than the first interfacial dielectric layer may, or may not, be present in the second composite gate electrode.
