Watch>> - Sapphire for GaAs, Indium Phosphide, & Other Semiconductors

Sapphire Wafer Carriers
Insaco, Inc has become recognized as a worldwide leader in custom machined ceramic and sapphire parts for the semiconductor industry. Through this experience, Insaco® offers multiple hole wafer carriers in sapphire for GaAs, Indium Phosphide, and other semiconductors.

Why Sapphire?

• Superior chip resistance
• Chemically resistant to all reagents used in processing
• Scratch resistant. Harder than any other optical material except diamond.
• Transparent
• Durable. Withstands repeated use and handling
• Best coefficient of thermal expansion match to GaAs.

Insaco® has also developed unique capabilities to fabricate wafers with one or more circular recesses; to serve as holder for other wafers. This includes single recess in the center as well as, for example, four 2” recesses in a single 6” carrier. The key is keeping the recess flat and parallel, and perhaps also polished. This is where innovation was required, and we are able to offer flat and parallel recesses to .0001” (2.5 micron).

Sapphire offers many advantages over quartz carriers:

• Higher thermal conductivity (42 W / mK @ 20°C).
• Higher melting temperature (2040 °C).
• Much greater hardness & scratch resistance - second only to diamond.
• Impervious to virtually all chemicals and reagents.

Features 

• Custom sizes for the processing of your 2",3", 4" and 6" GaAs wafers, with larger carrier sizes if required
• Available with or without perforations
• Laser marked for identification
• Scratch and chemical resistant

Benefits 

• Cost savings by giving you exactly what you need
• Flexibility in meeting your design specs
• Provides full documentation and continuous traceability
• Lends itself to repeated use without compromising the integrity of the wafer

Insaco Designers Guide
select materials of interest based on what is most important to your application. Once you specify which properties are most important, the "guide" searches our database of materials and presents you with various materials listing the selected properties ranked as you specify and often includes some other materials provided as references.

Watch>>>Ceramic Manufacturing and Machining Process with Insaco, Inc.

Insaco
Insaco has been fabricating precision parts from all technical ceramics since 1947. Approximately a third of our machining involves sapphire, but our capabilities go way beyond that. Insaco engineers welcome inquiries from designers contemplating specifying technical ceramics for their applications, whether prototype or full production. We only ship parts that meet agreed-to requirements, but are often able to respond to challenges and achieve results others cannot.

Watch>>>Precision Fabrication by Design

High Precision Machining of Hard Materials
Since 1947 Insaco® has been a precision machining and polishing fabricator of parts from all technical ceramics, sapphire, glass and quartz. We machine these materials to very precise tolerances (many times measured in millionths of an inch) for dimension, flatness, wedge and roundness or cylindricity. Our customers typically have a critical application that requires extremely tight tolerances in ultra-hard materials. We also have the capability to grind and polish spherical radius parts in a variety of hard materials, both inside and outside diameters, to optical requirements.

features include:

• Extremely high accuracy and tight tolerance machining
• Lights-out manufacturing
• Machine automation including large capacity envelope
• Automated centerless grinding
• High efficiency/low cost volume production
• Low-volume prototype machining
• 5-axis machining capability
• ITAR compliant
• High-volume robotic machining
• Video inspection and a Class 100 Cleanroom
• Extensive Quality Control protocols
• Sapphire tubes and polishing
