TITLE(s): PHOTO MASK TECHNICIAN, ELECTRON-BEAM (electron. comp.)
Generates computer tape or disk of processing instructions for use in electron-beam fabrication of
photo masks used in integrated circuit (IC) manufacture, using computer graphics system and software
and applying knowledge of photo mask layout: Reviews work order and specification manuals to
determine data required to lay out array (arrangement of integrated circuit layer patterns) for
reproduction onto photo mask. Enters commands into computer, using keyboard, to retrieve from data
file and display on display screen existing array format information. Calculates additional array
information required, such as array center and coordinates, number of rows and columns in array, and
location of test patterns in array, following specification manual and work order instructions.
Locates file (computer tape) relating to specified IC layer and loads tape into computer tape drive.
Enters specified commands into computer, using keyboard to retrieve IC layer pattern from file and
display pattern on array format on computer display screen. Positions IC layer patterns and test
patterns within array format on display screen, using knowledge of photo mask layout and computer
graphics. Enters electron-beam exposure instructions into computer and keys in commands to transfer
array data and exposure instructions onto computer disk or tape for use by PHOTO MASK MAKER,
ELECTRON-BEAM (electron. comp.) 972.382-018. May enter commands into computer, using keyboard, to
