Together, the two instruments offer precision IC die cross-sectioning; wedge polishing for TEM analysis; parallel lapping/deprocessing; backside grinding for LSM analysis; and prem FIB/TEM thinning. Allied High Tech Products Inc., Rancho Dominguez, CA; ph 310/635-2466, fax 310/762-6808.
Laser scanning confocal microscope
Using proprietary scanning technology to provide high-performance 3-D surface inspection, KovexVision examines materials without mechanically touching or probing the surface. Reflected laser light is collected from the focal point of a laser beam as it intersects with a sample surface. As the beam scans, a PC correlates reflections from the surface of the sample with the known position of the beam. The computer monitor then displays the data as a 3-D image. Specialized software allows this image to be viewed from any angle, rotated, and measured. KovexVision displays the 3-D sample image with all image points in focus simultaneously, allowing for precise point-to-point measurements in every dimension. Kovex Corp., Shoreview, MN; ph 612/486-9830, www. kovexcorp .com.
Gate oxide integrity test
This new technique, Bounded Step Current, overcomes the limitations of traditional means of measuring gate oxide integrity. It is available in ProCap v 6.3 software for the SSM 5200 yield enhancement tool. By measuring the IV characteristic of test structures with a current ramp, premature failure mechanisms are avoided. Since these test structures can be built into production wafer scribe lines, the method has no negative impact on fab production capacity, and it identifies gate oxide quality problems with a high level of certainty. Solid State Measurements Inc., Pittsburgh, PA; ph 412/787-0620, e-mail [email protected].
FPD surface analysis system
The VCA-4100 flat panel display (FPD) surface analysis system accepts panels up to 650 ? 550 mm in size, providing critical information on FPD surface characteristics. The panel is placed onto a large x-y stage, which is moved into the desired position. A droplet is then dispensed under computer control for precise sizing and released onto the substrate. The high-magnification lens and fiber-optic light source allow the droplet to be profiled; Windows 95 application software then automatically calculates the contact angle. Data and images can be stored and printed for future reference and analysis. AST Products Inc., Billerica, MA; ph 978/667-4500, e-mail [email protected].
Pulsed power generation
PowerMOD solid-state, high-voltage pulse modulators are designed for semiconductor and materials processing, offering very high reliability. They are composed of standardized solid-state switch modules that allow complete adjustability of process parameters and a broader operating range. PowerMOD model HVPM 20-2000 generates up to 40 MW of power in a single pulse 1000 times/sec, and handles over 2000 amps in current; other models provide pulses up to 120 kV in voltage.

Combined bake/fill module for LCDs
The latest in the MELP (modular equipment for LCD production) series of combo modules, BKFI-110/160, combines both a vacuum bake chamber and an LC filling chamber into one module. It allows empty cells to be heated under vacuum without exposing the sensitive LC material to excessive heat. Process time is greatly reduced via concurrent vacuum stages and lowered port LC viscosities. The dual chamber also eliminates the possibility of cell recontamination, because the cells do not need to be transferred from a separate oven to a filling chamber.

It is well suited to area monitoring for OSHA safety requirements (0.1 ppm for continuous exposure and 0.3 ppm for short-term exposure). The instrument is available in single-channel, three-channel, and six-channel configurations for sampling one or more locations. It has an internal sample pump, and analog and digital outputs with concentration alarms. Advanced Pollution Instrumentation Inc., San Diego, CA; ph 800/324-5190, fax 619/657-9816.
High-pressure gas probe
Model HPGP high-pressure gas probe monitors contaminants at line pressure, operating at pressures from 40 to 150 psig. Sizing sensitivity is available at 0.1 ?m with a flow rate of 0.1 SCFM. The probe is contained in a cylindrical pressure vessel that serves as a safety containment housing, and during operation the contaminant vessel is pressurized with dry nitrogen. If the pressure vessel leaks to ambient or if there is an internal gas leak into the vessel, power is disabled. The metal inlet fitting surfaces are electropolished stainless steel, providing compatibility with many nontoxic gases and aerosols.

Tip evaluation system
Available for all NanoScope Dimension and MultiMode scanning probe/atomic force microscopes, this tip evaluation system determines whether the tip meets a selected sharpness criterion or should be replaced. The package includes the proprietary tip evaluation software, as well as a roughness standard that is scanned as part of the evaluation. Based on the analysis, the software presents a worst-case tip sharpness in numerical and graphical form, including displaying an image of the tip itself. Digital Instruments, Santa Barbara, CA; ph 805/967-1400, fax 805/967-7717, e-mail [email protected].
Large-sample SPM
The VISTA-100 is a scanning probe microscope (SPM) whose innovative mechanical design and integration of the SPM controller into the computer chassis produces a very small footprint. It is designed to accept samples up to 6 ? 6 ? 1 in. (150 ? 150 ? 25 mm) onto the manual x-y stage. The translator and support block can easily be removed without the use of tools, allowing the instrument to accommodate samples up to 11 in. (280 mm) in width and 4 in. (100 mm) in height. Other design features include the use of gradient index lens technology to provide a view of the sample area and to focus the laser spot on the cantilever probe.
