An intrusion detection method for detecting an intrusion in data traffic on a data communication network parses the data traffic to extract at least one protocol field of a protocol message of the data traffic, and associates the extracted protocol field with a model for that protocol field. The model is selected from a set of models. An assessment is made to determine if a contents of the extracted protocol field is in a safe region as defined by the model, and an intrusion detection signal is generated in case it is established that the contents of the extracted protocol field is outside the safe region. The set of models may comprise a corresponding model for each protocol field of a set of protocol fields. |

The signal converter outputs a modified (multiphase) switching control signal that includes multiple separated on-periods that taken together approximate the duty cycle of the switching control signal while maintaining the same control loop frequency. The multiphase switching signal drives the power switching circuit to provide current to the inductor during each of the multiple separated on-periods so that the output voltage ripple decreases by a factor of the number of phases in the modified switching signal. In this way, if the ripple amplitude is kept same, the sizes of the passive components can be reduced by the factor of the number of phases in the modified switching control signal. |

Provided is a method of fabricating a semiconductor device, including the following. A first material layer, a second material layer and a mask layer are formed on a substrate. A portion of the second material layer is removed by performing a first etching process with the mask layer as a mask, so as to expose the first material layer and form a first pattern layer and a second pattern layer. A portion of the first material layer is removed by performing a second etching process with the mask layer as a mask, so as to expose a portion of the substrate. A portion of the substrate is removed by performing a third etching process with the mask layer as a mask, so as to form first trenches and second trenches. Sidewalls of the second trenches and a surface of the substrate form at least two different angles. |

Method of forming shallow trench isolation (STI) structures
A method of forming a trench isolation (e.g., an STI) for an integrated circuit includes forming a pad oxide layer and then a nitride layer over a semiconductor substrate, performing a trench etch through the structure to form a trench, depositing a trench oxide layer over the structure to form a filled trench, depositing a sacrificial planarizing layer, which is etch-selective to the trench oxide layer, over the deposited oxide, performing a planarizing etch process that removes the sacrificial planarizing layer and decreases surface variations in an upper surface of the trench oxide layer, performing an oxide etch process that is selective to the trench oxide layer to remove remaining portions of the trench oxide layer outside the filled trench, and removing the remaining nitride layer such that the remaining oxide-filled trench defines a trench isolation structure that projects above an exposed upper surface of the semiconductor substrate. |
