The Course Map	The Course Map is the starting point, which leads to Seven Chapters. You can view a brief example of each chapter by clicking on the information below.

Chapter One -- Course Introduction Course Outline	Intro Screen The course introduction presents a general overview and explains various navigational buttons and operating procedures. It also explains the quizzes, scoring and the progress report. The system hardware requirements are defined here as well.
	Button Functions The Button Function screen explains the use of each button that will be used to navigate throughout the course. Notice the Lips Button at the top of the screen, many screens are introduced via the Lips button which explains the purpose of the exercise. There is a total of six individual screens in this chapter, each explains a unique aspect of the training software.
Chapter Two -- Semiconductors and Test Course Outline	Intro Chapter two introduces the "Front End" and "Back End" manufacturing processes, namely fabrication and assembly/test. There is a quiz associated with each chapter, the results of each quiz appears in the Progress Report.
	Semiconductor Manufacturing The Semiconductor Manufacturing sections presents an overview of the "Front End" processing required to manufacture silicon devices. It begins with an explanation of chip layout, then shows the process of pulling silicon ingots. Next the topics of wafers and dice are explained. Wafer test, assembly, packaging and final test are also explained. This section makes extensive use of pictures and movies.
	Silicon Ingots Many topics begin with a written explanation and then a movie is used to reinforce the information.
	Die Attach Movie Movies are used throughout Chapter 2. The film footage is licensed from the popular Silicon Run series. Movies help visualize and better understand the various steps and equipment involved in the manufacturing process.
	Automatic Testing The second section of Chapter 2 explains ATE Test Systems and the peripheral equipment used in production testing. Various types of test systems, load-boards, probe-cards, wafer-probers, device-handlers and temperature forcing equipment are explained.
	Wafer Prober In this picture an older style wafer prober is used to illustrate the internal workings of a probe machine. Fully enclosed (clean environment) probers are also included in this discussion.
	There are many more screens in this section.
Chapter Three -- Terminology of Test Course Outline	Intro Chapter Three defines the "Language" or "Terminology" of test. This information is presented as narration, interactive information and text based definitions.
	Device Pins This screen defines the various types of pins (and their functions) as found on a digital device. It explains that each pin type will require specific tests, based on it's function.
	Terminology Some things are best explained in written form. There are three screens of terms organized by their functions. A complete Glossary is also available via a Pop-Up Menu on the right mouse button.
Chapter Four -- What's in the Test System? Course Outline	Intro Chapter Four presents an overview of a typical ATE Test System, and focuses on several key compontens of the system.
	Test System Overview This screen introduces the different sections of the tester and explains each function. This lesson is very interactive, first an animation is used to present an overview, then the student interacts with the screen to learn about specific areas and functions of the test system. We call this interactive screen a "Click Screen" because you can select, using the mouse, the subject that will be explained.
	The PMU In order to understand DC Parameter testing, it is essential to understand how the PMU functions. The details are explained here using animation's and a Click Screen.
	Pin Electronics Card In order to understand Functional Testing, it is essential to understand how the Pin Electronics functions. The details are explained here using animation's and a Click Screen.
Chapter Five -- Device Specifications Course Outline	Intro Every test program is based upon a device specification, we must first understand device specifications in order to make sense of the test program.
	What are Device Specifications? Device specifications can take several different forms, this section addresses these issues.
	Logic Diagrams A Logic Diagram is included in most specifications. They often contain very useful information, it is necessary to be able to correctly read these diagrams. This is an animated Click Screen which is actually fun to use (and you will be learning in the process).
	Understanding a Data Sheet Specification Learning to understand the "DC Characteristics" section of the specification can be a very frustrating experience. We have attempted to make it interesting, less confusing and hopefully less frustrating, using an interactive screen.
Chapter Six -- DC Parameters Course Outline	Intro Chapter Six explains test methodologies. It introduces the concepts of DC parameter testing and explains how the specification and test system hardware work together to insure that the device under test meets or exceeds it's specifications.
	Explaining a DC Test This format is used to explain each DC test. The buttons on the left select the various topics. The "RUN" button starts the animation, which displays in the main window. "WHY" opens a window which explains the purpose of each test. "Test Method" is a text version of the animation. The "Resistance" button opens a series of windows which explains the measurement path associated with the test. Trouble-shooting explains how to diagnose problems. "Key Points" summarizes the important issues.
	Datalogs The datalog contains valuable information. An actual datalog for each test illistrates passing and failing conditions. The Lips are used to explain each measurement.
	Actual Test Examples To help illistrate how the tests are implimented, each test has been programmed on the ATE Systems indicated above. An example of the actual test is display by pressing the appropriate button.
	The Quiz Each section of the training has an associated quiz. The results from the quiz are stored in an individual data base for each student.
	The Virtual PMU The Virtual PMU is used to reinforce the students understanding of each test procedure. The VPMU must be correctly programmed, based on the device specification, the results of this activity are stored in the student database. Programming the VPMU is very similar to setting the test conditions on any popular test system.
Chapter Seven - Troubleshooting Course Outline	Troubleshooting The final chapter addresses the issue of trouble-shooting. Although each DC test has an associated trouble-shooting section, we felt additional skills would be useful. The Introduction section points out the various items that COULD be causing a failure, then explains how to go about eliminating each suspect. A general approach to trouble-shooting is spelled out.
	Learning to Listen for Clues There are six different problems that must be solved. Each problem is presented as a story containing important facts, but also leaving out important information. It is up to you to determine the steps that will be taken to solve each problem. All of the problems (and stories) are based on actual Test Floor experiences. Many engineers really enjoy working through these exercises!
	Where Is the Problem? After listening to each story you will be armed with useful information. Based on that data you must decide upon what you believe is causing the problem (the DUT, Interface Hardware, Test System or Test Program). With each selection you will gain additional information, some useful, some not. Ultimately you will solve the problem. The most expedient method is explained after the problem is solved. You can then compare you selections with the proper (fastest) sequence. These exercises have proven to be very beneficial in helping engineers improve their trouble-shooting skill.
Progress Report Course Outline	A database stores the individual student information which is then displayed in the Progress Report. A record is kept as the student progresses through the course material. When the student completes the entire course and achieves a 75% passing result or better, a completion window appears on this screen and a completion code is issued. The Progress report can be printed or a coded text file can be produced and e-mailed to Soft Test. We will issue a "Certificate of Completion" upon receipt of proof of satisfactory completion. Many managers find the progress report a useful tool in evaluating the effectiveness of the training.
