The Modeling of Lpcvd in Single-wafer Reactors as a Tool for Process Optimization and Equipment Design
An overview is given of the modeling of the hydrodynamics, transport phenomena and chemical reactions in single-wafer LPCVD reactors, both at the macroscopic (reactor-scale) and a t the microscopic (feature-scale) level. Examples of modeling results f o r single-wafer silicon LPCVD from silane and tungsten LPCVD from tungsten hexafluoride and hydrogen a r e presented and comparisons a r e made ...
متن کاملOptimum Design of Hydraulic Excavator
Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". In this paper the hydraulic shovel excavator is analyzed through the D-H method. The shovel working device with the bucket capacity of 36m3 is optimized. The determination of the objective function, variables and constraints are described in ...
متن کاملOptimum Design of Sewer Collection Networks
Various methods have been used to economically design wastewater and stormwater collection systems. In this article, Discrete Differential Dynamic Programming (DDDP) which is a subsection of dynamic programming (DP) was used. For each pipe network, various alternatives such as depth and slope of pipe laying and various diameters could be considered to satisfy hydraulic and engineering constrain...
