Course Description

Explores quality control methods used in semiconductor manufacturing, including statistical process control (SPC), control charts, performance representation and capability measurements. Emphasizes computer manipulation of actual data for analysis and design of quality. Audit available.

Addendum to Course Description

This course follows the process of collecting and analyzing data as it would be done in a semiconductor manufacturing line to characterize process performance. The data will be used to examine effects of sampling", utilize methods of representation, and options for process control as would be done using process control charts. Additional analysis will be done using capability indices and examining opportunities for improvement. Additionally students will study the history and philosophy of managing quality in manufacturing.

This course is primarily offered in a web-based format.  Students should have access to a computer with data analysis software (spreadsheets)", word processing, and internet access (all are available on campus.) Students must be able to manipulate data mathematically, and communicate meaning in written form, using the English language.

Intended Outcomes for the course

On completion of this course the student should be able to:

  • Understand the history and requirements for effective quality systems in modern manufacturing
  • Understand and utilize the tools of quality systems
  • Collect, analyze and plot variable and attribute data
  • Determine and use capability indices to describe a process
  • Create and react to control charts
  • Understand the sources of costs for implementing (or not implementing) quality systems
  • Describe various quality systems used in modern manufacturing

Outcome Assessment Strategies

Assessment of student performance in this course will be based on students’ ability to demonstrate knowledge and understanding of the required competencies", as determined through homework assignments and class participation. Assignments will include problem sets and projects involving analysis of data sets, statistics, case studies, and evaluation methods. Class work can involve group work and presentation, as well as written examinations.
