Data Engineering for the Analysis of Semiconductor Manufacturing Data

We have analyzed manufacturing data from several different semiconductor manufacturing plants, using decision tree induction software called Q-YIELD. The software generates rules for predicting when a given product should be rejected. The rules are intended to help the process engineers improve the yield of the product, by helping them to discover the causes of rejection. Experience with Q-YIELD has taught us the importance of data engineering -- preprocessing the data to enable or facilitate decision tree induction. This paper discusses some of the data engineering problems we have encountered with semiconductor manufacturing data. The paper deals with two broad classes of problems: engineering the features in a feature vector representation and engineering the definition of the target concept (the classes). Manufacturing process data present special problems for feature engineering, since the data have multiple levels of granularity (detail, resolution). Engineering the target concept is important, due to our focus on understanding the past, as opposed to the more common focus in machine learning on predicting the future

Principles for aerospace manufacturing engineering in integrated new product introduction

This article investigates the value-adding practices of Manufacturing Engineering for integrated New Product Introduction. A model representing how current practices align to support lean integration in Manufacturing Engineering has been defined. The results are used to identify a novel set of guiding principles for integrated Manufacturing Engineering. These are as follows: (1) use a data-driven process, (2) build from core capabilities, (3) develop the standard, (4) deliver through responsive processes and (5) align cross-functional and customer requirements. The investigation used a mixed-method approach. This comprises case studies to identify current practice and a survey to understand implementation in a sample of component development projects within a major aerospace manufacturer. The research contribution is an illustration of aerospace Manufacturing Engineering practices for New Product Introduction. The conclusions will be used to indicate new priorities for New Product Introduction and the cross-functional interactions to support flawless and innovative New Product Introduction. The final principles have been validated through a series of consultations with experts in the sponsoring company to ensure that correct and relevant content has been defined

Sound recordings of leading professors of Spanish Manufacturing Engineering. Analysis of contents.

ISBN 978-84-09-10387-4"Academic Lives in Industrial Engineering" is one of the different initiatives developed by PATRIF, a Working Group of the Manufacturing Engineering Society (MES) / Sociedad de Ingeniería de Fabricación (SIF). This activity intends to create a sound recording archive with interview format, in order to disseminate the trajectory of the great professors of the Spanish Industrial Engineers Faculties. It seeks to preserve and bring closer to the new generations the experiences and the personality of these professors, with a story told in the first person. This work aims to show the characteristics of this activity, presenting the profile of the interviewees, pointing out the most outstanding aspects of their interventions, carrying out an analysis of the follow-up of the broadcasted interviews and assessing their impact. Despite other areas of engineering are covered in this initiative, present work limit its analysis to the group of professors who have developed their academic and professional life within the Manufacturing Engineering and it also wants to serve as tribute and recognition to their trajectories and dedication to the Spanish Manufacturing Engineering.Universidad de Málaga.

The presented projects have been selected to prepare engineering students with the adequate knowledge and skills required in organizing product based project, formulating problems, generating and evaluating alternatives, preparing technical documentation and considering the sustainable and economic constraints for the product development and realization stage using the integration of various disciplines in mechanical and manufacturing engineering. This book is generally suitable as a reference to project-oriented problem-based learning (POPBL) activities at engineering institutions

Engineering Workflow: The Process in Product Data Technology

The prevailing paradigm for enterprises in the new decade is undoubtedly speed. This enterprise view is driven by the availability of e-business technology that enables new forms of collaboration between companies. The rapid developments in e-business also have an impact on the future of engineering organizations. This paper focuses on the early phases of a product’s life cycle, i.e. between initial concept and release to manufacturing. New engineering workflow capabilities are presented, that have been tailored to speed up the engineering of new products

Microelectronics Process Engineering at San Jose State University: A Manufacturing-Oriented Interdisciplinary Degree Program

San Jose State University\u27s new interdisciplinary curriculum in Microelectronics Process Engineering is described. This baccalaureate program emphasizes hands-on thin-film fabrication experience, manufacturing methods such as statistical process control, and fundamentals of materials science and semiconductor device physics. Each course of the core laboratory sequence integrates fabrication knowledge with process engineering and manufacturing methods. The curriculum development process relies on clearly defined and detailed program and course learning objectives. We also briefly discuss our strategy of making process engineering experiences accessible for all engineering students through both Lab Module and Statistics Module series

Numerical modelling and simulation in sheet metal forming

The application of numerical modelling and simulation in manufacturing technologies is looking back over about a 20–30 years history. In recent years, the role of modelling and simulation in engineering and in manufacturing industry has been continuously increasing. It is well known that during manufacturing processes simultaneous the effect of many different parameters can be observed. This is the reason why in former years, detailed analysis of manufacturing processes could have been done only by time-consuming and expensive trial-and-error methods. Due to the recent developments in the methods of modelling and simulation, as well as in computational facilities, modelling and simulation has become an everyday tool in engineering practice. Besides the aforementioned facts, the emerging role of modelling and simulation can also be explained by the growing globalisation and competition of the world market requiring shorter lead times and more cost effective solutions. In spite the enormous development of hardware and software facilities, the exclusive use of numerical modelling still seems to be very time- and cost consuming, and there is still often a high scepticism about the results among industrialists. Therefore, the purpose of this paper is to overview the present situation of numerical modelling and simulation in sheet metal forming, mainly from the viewpoint of scientific research and industrial applications

The use of simulated games in an undergraduate course manufacturing processes

Simulation games bring the real engineering situation into class room. They are ideally suited to situations where the size and cost of some systems cannot be replicated in educational institutions, e.g. large-scale production facilities and manufacturing processes. Students undertaking a course in Manufacturing Processes participated in a role-playing game within a simulated manufacturing environment for the production of LEGO widgets. The game has three discrete phases; each with a briefing session, a production “run” and a debriefing session. It encourages observation and discussion of possible improvements required to increase productivity, and also visualizes some of the manufacturing concepts. This paper describes the exceptional learning outcomes achieved, the explicit understanding of manufacturing strategies and an insight into the approaches taken by world class manufacturers to maximise production. Surveys of students, taken before and after the game, revealed that they gained a greater appreciation for the course content by being immersed in this simulated scenario. The game also illustrated the importance of good team interaction, the application of different problem-solving techniques, and proved the odd adage “work smarter not faster”
