  • Patent number: 9478489
    Abstract: The width of scribe lines may be reduced in semiconductor devices by applying a process technique in which trenches may be formed first from the rear side on the basis of a required width of the corresponding trenches, while subsequently it may be cut into the substrate from the front side on the basis of a reduced thickness of the corresponding saw blades, thereby also enabling a reduction of the scribe line width. Furthermore, contamination of the front side, i.e., of the metallization system, may be reduced, for instance, by performing an optional intermediate cleaning process.

  • Patent number: 9425394
    Abstract: Provided are methods of fabricating memory cells such as resistive random access memory (ReRAM) cells. A method involves forming a first layer including two high-k dielectric materials such that one material has a higher dielectric constant than the other material. In some embodiments, hafnium oxide and titanium oxide form the first layer. The higher-k material may be present at a lower concentration. In some embodiments, a concentration ratio of these two high-k materials is between about 3 and 7. The first layer may be formed using atomic layer deposition. The first layer is then annealed in an oxygen-containing environment. The method may proceed with forming a second layer including a low-k dielectric material, such as silicon oxide, and forming an electrode. After forming the electrode, the memory cell is annealed in a nitrogen containing environment. The nitrogen anneal may be performed at a higher temperature than the oxygen anneal.

  • Patent number: 9330979
    Abstract: A low Rdson LDMOS transistor having a shallow field oxide region that separates a gate electrode of the transistor from a drain diffusion region of the transistor. The shallow field oxide region is formed separate from the field isolation regions (e.g., STI regions) used to isolate circuit elements on the substrate. Fabrication of the shallow field oxide region is controlled such that this region extends below the upper surface of the semiconductor substrate to a depth that is much shallower than the depth of field isolation regions. For example, the shallow field oxide region may extend below the upper surface of the substrate by only Angstroms or less. As a result, the current path through the resulting LDMOS transistor is substantially unimpeded by the shallow field oxide region, resulting in a low on-resistance.
