Gaussmeters
Solid-State Pulsed Nd:YAG Laser:
and Hall Probes: Lake Shore's Series 400 gaussmeters and Hall probes may be used in varying configurations for magnetic field test and measurement applications from -269 to 75°C. Handheld and benchtop gaussmeters can measure magnetic fields from 0.02 G to 300 kG. Custom liquid displays, 20-character by two-line vacuum fluorescent message-based displays, or analog displays are available. Resolutions range from 3-1/2 digits in the handheld unit to 4-3/4 digits in larger models, and full-function keypads offer function access with one or two keystrokes. Other features include the display and capture of maximum ac and dc amplitude, programmable corrected analog output, autoranging, interchangeable probes, and IEEE-488 and RS-232 interfaces.

High-Performance
The Surelite II from Continuum generates outputs of 650 mj in the infrared (1,064 fjm) and 300 mj in the green (532 /urn), and affords a uniform beam profile. The pumpchamber design uses one rod and one flashlamp and incorporates a graphite resonator structure and gaussian mirror optics. The compact unit is air-cooled, and the controls, indicators, and computer interface are readily accessible on small power supplies. Third and fourth harmonic generation options are available.

In-Line Semiconductor Manufacturing Process Control: KLA Instruments' Yield Management System provides inline process monitoring that accelerates defect detection and elimination programs in advanced integrated circuit manufacturing facilities. The system couples 0.20 ^m detection of process defects and particles with inspection speeds of 3 to 6 minutes for full, patterned wafers. Defect images and defect data are integrated into a relational database. The three-part system features a KLA 2111 inspection tool, a KLA 2550 data and image analysis workstation, and a KLA 2608 off-line review station that supplements defect information gathered from the KLA 2111 and can also be used to review and classify defect information from the workstation.

MicroLIMS operates in Microsoft® Windows 3.1 and features ready-to-use computer interfaces for most equipment. Each module provides a graphical representation of the instrument or system and a hardware driver that allows users to operate the instrument via computer. Modules also can be linked together. MicroLIMS uses other Windows programs and the Windows Dynamic Data Exchange, and Excel is used for the macro programming environment and as a database for storing and manipulating data. The software is available for standard vacuum components and complete systems. Circle No. 56 on Reader Service Card.
