Design guidelines for manufacturability
… Existing approaches to improving manufacturability are helpful in the latter stages of the design process and usually involve corrective redesign. To avoid redesign, designers require appropriate guidance in the early stages of the design process. Guidelines, that is prescriptive …

VLSI Physical Design for Manufacturability and Reliability
… design techniques are presented to improve the manufacturability. We present a novel metal fill insertion methodology in Chapter 6 for lithography. Trade-off between printability and coupling capacitance are considered. In Chapter 7, dummy features and boundary based method are proposed to …

Efficiency, manufacturability, and modeling challenges in structural design optimization
… by additive manufacturing, that accommodate the manufacturability constraints of the direct ink writing process. To accomplish this, the toolpaths of each layer are defined by contours of a level-set function. With this representation, we can define the manufacturing constraints and the material …

Manufacturability and Analysis of Topologically Optimized Continuous Fiber Reinforced Composites
… the technology cannot yet robustly guarantee manufacturability. For this reason, substantial post-processing of an optimized design consisting of manual fiber replacement and subsequent Finite Element Analysis (FEA) is still required.</p> <p>To automate this post-processing in two dimensions, …

Design for manufacturability with regular fabrics in digital integrated circuits
Integrated circuit design is limited by manufacturability. As devices scale down, sensitivity to process variation increases dramatically, making design for manufacturability a critical concern. Designers must identify the designs that generate the least systematic process variation, e.g., from …

Manufacturability Assessment of the Navy Integrated Power and Energy Corridor (NiPEC)
… development focuses on evaluating the design’s manufacturability and the feasibility of manufacturing and installing the system aboard ships. This study explored the principles of Design for Manufacturability (DFM) and Design for Production (DFP) and then defined how these concepts apply to the …

Design for manufacturability methodology and data representation framework for machined components
… through the use of techniques such as Design For Manufacturability (DFM) and Design For Assembly (DFA). DFM techniques have to be automated to take advantage of the vast advances in CAD and CAM systems. However, the automation of DFM has been constrained, especially for machined components, by the …

Manufacturability of lab on a chip devices: tolerance analysis and requirements establishment
Decisions made during the first stages of the design process can have an impact on the cost, quality and performance of a product. Variation in assemblies, if not managed correctly during the design stage, can have a negative impact on the success of the product. This work analyzes the Daktari CD4+ …

Manufacturability of gallium arsenide/aluminum gallium arsenide lasers grown by molecular beam epitaxy
The performance of high-power graded index separate confinement heterostructure single quantum well lasers grown by molecular beam epitaxy depends primarily on the quality of $Al\sb{x}Ga\sb{1-x}As$ layers, the interface roughness, and the control of residual oxygen incorporation into the active …

Meso-scale FDM material layout design strategies under manufacturability constraints and fracture conditions
In the manufacturability-driven design (MDD) perspective, manufacturability of the product or system is the most important of the design requirements. In addition to being able to ensure that complex designs (e.g., topology optimization) are manufacturable with a given process or process family, …

A unified approach to modeling, verifying, and improving the manufacturability of mechanical assemblies
… shown how this model can be used to verify the manufacturability of a mechanical assembly design. It is also shown how the model and the results obtained from it can be used to improve the level of manufacturability of a design if it is found to be unacceptably low. To validate the effectiveness …

A truly embedded test structure for design-for-manufacturability, hardware security and VLSI testing
As the feature sizes continue to shrink in advanced VLSI technologies, the impact of process variations on yield losses has become significant. Moreover, the process variations in path delays are increasingly dependent on circuit context. Given this 'neighborhood' dependence, characterization of …

Physicochemical and computational approaches for the prediction of the manufacturability of active pharmaceutical ingredients
… currently available for the prediction of manufacturability of tablets are not adequately representative of bulk solid properties. There is, therefore, a need to develop new and appropriate characterisation techniques for use in pharmaceutical material evaluation. This is particularly …

Manufacturability of lab-on-chip devices : dimensional variation analysis of electrode foils using visual technology
Electrodes are necessary components for measuring changes in electrical properties in many microfluidic devices. Daktari CD4 Cell Counter system utilizes an interdigitated electrode foil in order to measure the concentration of the CD4 cells in an assay chamber by measuring the impedance drop. Thus …
