A user interface for Wafer Inspection Reclassification

Published on

Wafer Inspection Reclassification (WIR) is a monotonous and repetitive task of manually checking semiconductor chips with an optical inspection system. An appropriate user interface was needed to minimise physical and mental strain for operators and help them to make the right decisions, faster.

    9. 9. Field study at KLA Tencor labs<br />understandexplore define<br />Field Study<br />After an examination of user requirements (documentation review, interviews with product experts and a field study of ICOS operations), we came up with six scenarios of use.<br />

    11. 11. understand explore define<br />Scenarios of use<br />We composed realistic stories to describe in detail how different user groups could use the future tool in a variety of contexts depending on the type of wafer, whether working offline/online, or in different locations around the world.<br />Samples from the Scenarios of use for the future WIF system<br />

    13. 13. Outcome <br />Our design for the user interface helped KLA Tencor to reduce the physical and mental strain for operators performing the Wafer Inspection Reclassification and allow them to make the right decisions, faster.<br />
