GLOBAL FUNCTIONS
The SCC user interface is designed to provide a number of global functions that are applicable
(in general terms) to all implementations of the SCC:
•
Security (user identification)
•
Context specification
•
Error avoidance, detection, and correction
•
On-line help
•
Alarm management
•
User configuration and control
For some of these global functions, details of the actual implementation may differ somewhat
from site to site. This section provides guidelines for implementing these global functions,
using examples drawn from Release 1.0 of the SEMATECH implementation of the SCC.
9.1
Security
In many engineering or manufacturing environments, security procedures are implemented to
control unauthorized access to sensitive information or functionality. Security is of particular
concern in the semiconductor manufacturing industry because
•
Avoidable errors in the manufacturing process can significantly reduce yield and add to the
already high cost of producing semiconductors.
•
Semiconductor manufacturing equipment is costly and potentially hazardous to the health
and safety of workers. To avoid damage to equipment and manufacturing personnel, most
companies limit operation of equipment to certified technicians who have received
extensive training in procedures relating to correct handling of wafers and safe operation of
equipment.
•
The manufacture of semiconductors is a highly competitive business. Uncontrolled access
to proprietary information related to product characteristics and engineering or
manufacturing processes can endanger a company’s competitive position in domestic and
international marketplaces.
