Abstract

This report will present the use of Least-Squares method in Electronic Product such as Integrated Circuit (IC) that manufactured by semiconductor industry. In every production process in industries, there always have reject items in production line. There are many methods to solve this problem in industries but currently the industry need an alternative and simple method to solve this problem in order to improve their previous statistical analysis method. The objective of leastsquares method is to help industrial engineers to predict their output of product based on the mathematical model that have been developed in this project In order to achieve the objective of this project, several sample data is collected from the semiconductor industries to develop a reliable linear mathematical model. This model can be applied to predict the future output based on any kind of input data collected from production. This report will begin with a general introduction the project including the problem statements and objectives then moving on to the understanding of linear least-squares method and the development of mathematical model. Besides that, the development of graphical user interface (GUI) software by using Visual Basic Program will be discussed as well. Finally, suggestions for future implementations will be included.
