Optimization of the positioning system of semiconductor chip testing
Kotian, Tomáš ; Jankovský, Jaroslav (oponent) ; Otáhal, Alexandr (vedoucí práce)
The goal of this diploma thesis was to gather theoretical information on the possibilities of chip testing and subsequently design and apply necessary changes for the semi automatic positioning system, which would ensure its ability to test chips with the use of probe cards. Semi automatic positioning system is a result of a bachelor thesis, which ensured the ability of the machine to provide testing with the use of a resistance system created on a thick layer. The practical part of this thesis is focused on providing an accurate testing of the machine’s parametres and designing and applying necessary changes for the mechanical part of the machine. Furthermore, the thesis also describes the design and creation of an application with automatic detection of a chip, which is used for controlling the machine. The last part of the thesis describes the testing of the machine, which was realized with the use of two different sized chips.

Design of a semi-automatic positioning system for measuring of semiconductor chips
Kotian, Tomáš ; Vyroubal, Petr (oponent) ; Otáhal, Alexandr (vedoucí práce)
The aim of this bachelor thesis is to design and create a system for a semi-automatic positioning system for the test of semiconductor chips. The work solves the problem with the implementation design to achieve the highest possible accuracy for contacting with the help of a probe card. Furthermore, the work deals with the selection of a suitable control unit for stepper motors and finally to create a program for focusing and centering the chip using the image from the camera.

Kotian, Tomáš
The aim of this work is to design a semi-automatic positioning system for the testof semiconductor chips. The work solves the problems with the implementation of the constructionto achieve the highest possible accuracy for contacting with probe card. Next, the work deals withthe selection of a suitable control unit for stepper motors and finally to create a program to controlthe system and display image from the camera to the computer. The last requirement for the programis detection of chips with the camera image and automatic centering with a probe card.
