摘要:
A semiconductor circuit and method of fabrication is disclosed. In one embodiment, the semiconductor circuit comprises a metal-insulator-metal trench capacitor in a silicon substrate. A field effect transistor is disposed on the silicon substrate adjacent to the metal-insulator-metal trench capacitor, and a silicide region is disposed between the field effect transistor and the metal-insulator-metal trench capacitor. Electrical connectivity between the transistor and capacitor is achieved without the need for a buried strap.
摘要:
The present invention relates to a method of fabrication process which integrates the processing steps for fabricating the trench MIM capacitor with the conventional middle-of-line processing steps for fabricating metal contacts, so that the inner metallic electrode layer of the trench MIM capacitor and the metal contact of the FET or other logic circuitry components are formed by a single middle-of-line processing step and comprise essentially the same metallic material. The semiconductor device contains at least one trench metal-oxide-metal (MIM) capacitor and at least one other logic circuitry component, preferably at least one field effect transistor (FET). The trench MIM capacitor is located in a trench in a substrate and comprises inner and outer metallic electrode layers with a dielectric layer therebetween. The FET comprises a source region, a drain region, a channel region, and at least one metal contact connected with the source or drain region.

A method for generating a patterned SOI photomask used for embedded DRAMs is described. The method systematically identifies embedded DRAM areas to be excluded from the SOI process and generates the shapes to be printed on the photomask so that the embedded DRAM may be fabricated on bulk silicon. The method includes the steps of: identifying and sorting DRAM array well shapes by common electrical net, resulting in a single array well shape for each electrical net (i.e., embedded DRAM cell). Next, all the n-band contacts touching a given array well shape are collected. These shapes are merged by common electrical net. A shape is then generated which is the smallest enclosing rectangle of the common electrical net of the n-band contact shapes. This represents the patterned SOI shape and defines the bulk areas onto which the embedded DRAM is to be built. Accordingly, the embedded DRAM macro is constructed in bulk areas while the logic is constructed in SOI.

An improved semiconductor capacitor and method of fabrication is disclosed. Embodiments utilize a deep trench which is then processed by performing a pre-amorphous implant on the trench interior to transform the interior surface of the trench to amorphous silicon which eliminates the depletion region that can degrade capacitor performance.
摘要:
A semiconductor structure and a method for fabricating the semiconductor structure provide a field effect device located and formed upon an active region of a semiconductor substrate and at least one of a fuse structure, an anti-fuse structure and a resistor structure located and formed at least in part simultaneously upon an isolation region laterally separated from the active region within the semiconductor substrate. The field effect device includes a gate dielectric comprising a high dielectric constant dielectric material and a gate electrode comprising a metal material. The at least one of the fuse structure, anti-fuse structure and resistor structure includes a pad dielectric comprising the same material as the gate dielectric, and optionally, also a fuse, anti-fuse or resistor that may comprise the same metal material as the gate electrode.
摘要:
A DRAM cell in a substrate has a deep trench (DT) extending from a surface of the substrate into the substrate, a word line (WL) formed on the surface of the substrate adjacent the deep trench, and oxide (TTO) disposed in a top portion of the trench and extending beyond the trench in the direction of the word line. In this manner, when silicided, there is oxide rather than silicon on the surface of the substrate in a gap between the word line (WL) and a passing word line (PWL) disposed above the deep trench.
