Since CMOS technology moved to sub-40nm node and beyond, the remarkable challenges have been noticed in dry etch, wet clean and the subsequent metal deposition process of contact loop. Contact etch has been proven as one of the most critical roles for yield enhancement. It not only needs to overcome the incoming challenges such as poor PR profile/CDU and CESL (Contact Etch Stop Layer) nitride pinch-off,...
A simulation analysis method of Duffing chaotic system circuit based on Simplorer 7.0 is presented. The circuit level simulation of Duffing chaotic system is achieved by modeling the non-linear restoring force term of Duffing chaotic system and other circuit element, such as sinusoidal voltage source, analog operational amplifiers, resistors and capacitors, etc. In this paper, it focuses on the main...
Epidemic Routing offers a reliable approach to transmitting data in opportunistic networks, which has developed a few of variations so far. However, these algorithms have some redundant control overhead in sensing neighbor nodes and exchanging data packets. To address the issue, we propose a high-efficiency low-delay routing algorithm based on exchange of increments in packet indexes. Our algorithm...
This paper analyzed the electromagnetic disturbances in the driving system of a fuel cell bus. First, the distribution of the disturbance source in the driving system surveyed by measurement was introduced. Then, the characteristics of the conductive emission were presented. Based on the multiconductor transmission line model, the paper analyzed the electromagnetic conductive interference in the driving...
Now, a model-based software developing method is promoted by the OMG through the specification of MDA (model driven architecture). In this paper, an application strategy of the method on component development and assembly is proposed, the meta-model and MOF (meta object facility) of MDA for component are described, and then analyzed the component model and model assembly. The feasibility of the technology...
