A Quality Gate is a special milestone in a software project. Quality Gates are located before a phase that is strongly dependent on the outcome of a previous phase. They are especially useful between phases in which breaches in disciplines must be overcome. Such a breach typically occurs, for example, when embedded software must be transferred to a hardware chip. Quality Gates are more general than Milestones; Quality Gates can be used in larger set of more or less similar projects, whereas milestones must be defined for each project from scratch. Each Quality Gate includes a check of documents relevant to the previous phase. Unlike a software review, this check is only formal; no deep check on the contents of applicable documents is conducted in a Quality Gate. A Quality Gate demands a set of documents and includes special requirements on these documents, both of which are detailed in a checklist. The check itself is performed in a session with decision makers and domain experts. Depending on their decision, the project can be canceled, put on hold, or approved to proceeded normally. Unfortunately, the term Quality Gate is not used consistently.

An anneal of a gate recess prior to formation of a gate contact, such as a Schottky contact, may reduce gate leakage and / or provide a high quality gate contact in a semiconductor device, such as a transistor. The use of an encapsulation layer during the anneal may further reduce damage to the semiconductor in the gate recess of the transistor. The anneal may be provided, for example, by an anneal of ohmic contacts of the device. Thus, high quality gate and ohmic contacts may be provided with reduced degradation of the gate region that may result from providing a recessed gate structure as a result of etch damage in forming the recess.

Reprogrammable non-volatile memory using a breakdown phenomena in an ultra-thin dielectric
A reprogrammable non-volatile memory array and constituent memory cells is disclosed. The semiconductor memory cells each have a data storage element constructed around an ultra-thin dielectric, such as a gate oxide. The gate oxide is used to store information by stressing the ultra-thin dielectric into breakdown (soft or hard breakdown) to set the leakage current level of the memory cell. The memory cell is read by sensing the current drawn by the cell. A suitable ultra-thin dielectric is high quality gate oxide of about 50 Å thickness or less, as commonly available from presently available advanced CMOS logic processes. The memory cells are first programmed by stressing the gate oxide until soft breakdown occurs. The memory cells are then subsequently reprogrammed by increasing the breakdown of the gate oxide.

Multi-layer high quality gate dielectric for low-temperature poly-silicon TFTs
InactiveUS20060105114A1Quality improvementSolid state diffusion coatingChemical vapor deposition coatingCapacitanceEngineering
A method and apparatus that is useful for forming a high quality gate dielectric layer in MOS TFT devices using a high density plasma oxidation (HDPO) process. The HDPO process forms a good interface and then a second layer, which has good bulk electrical properties, is deposited at a higher deposition rate over the HDPO layer. In one embodiment a thin HDPO process layer is formed over the channel, source and drain regions to form a high quality dielectric interface and then one or more dielectric layers are deposited on the HDPO layer to form a high quality gate dielectric layer. The HDPO process generally entails using an inductively and / or capacitively coupled RF energy transmitting device to generate and control the plasma generated over the surface of the substrate and injecting a gas containing an oxidizing source to grow the interfacial layer. A second dielectric layer may then be deposited on the surface of the substrate using a CVD or plasma enhanced CVD deposition process. Aspects of the present invention also provide a cluster tool that contains at least one specialized plasma processing chamber that is capable of depositing a high quality gate dielectric layer. The cluster tool is advantageous because it supports both the pre-processing steps, such as, preheating the substrate, pre-cleaning the surface of the substrate prior to processing, and cool down after processing, all in a single controlled environment.

The silicon wires formed around metal particles by crystal growth have the problem of metal pollution. For its solution, in the present invention, a silicon bridge is formed through standard silicon processes such as the lithography and the wet etching using hydrofluoric acid performed to an SOI substrate. Thereafter, a thermal oxide film is desirably formed at a high temperature to form a high-quality gate insulating film. It is also desirable to form a coaxial gate electrode. Then, after burying the bridge sections of the silicon bridge in a resist film, the silicon on the bridge girders is removed, and thereafter, the silicon wires buried in the resist film are collected. In this manner, the silicon wires can be collected without dispersing into the hydrofluoric acid solution. Then, a transistor using the silicon wires as a channel is formed.
