This was an art installation in UT's Blanton Museum of Art in Austin, Texas called How to Build Cathedrals by Cildo Meireles. This is only part of the installation, though. The top is cow bones with a column of communion wafers leading down to the floor which is covered with pennies. There's a transparent black curtain all the way around the exhibit. It was a very impressive and enveloping display. According to Blanton's site, the exhibit used 600,000 pennies, 800 communion wafers, 2000 cattle bones.

These scans come from my rather large magazine collection. Instead of filling my house with old moldy magazines, I scanned them (in most cases, photographed them) and filled a storage area with moldy magazines. Now they reside on an external hard drive. I thought others might appreciate these tidbits of forgotten history.

Due to the less mismatched lattice and stable chemical and physical properties, sapphire(Al2O3) wafer is the popular substrates for III-V nitrides, superconductor and magnetic epi-film. They are widely used in GaN and thin-film epitaxial growth, silicon on sapphire, LED market and optics industry.
CRYSCORE is a professional sapphire wafer supplier who manufactures 99.999% high purity single crystal polished sapphire wafers for epitaxy. And our sapphire (Al2O3) substrates feature excellent surface finish, which is the key LED parameter.

FEATURES OF SINGLE CRYSTAL SAPPHIRE
1. Sapphire has a high optical transmittance, so it is widely used as microelectronic tube dielectric material, ultrasonic conduction element, waveguide laser cavity and other optical elements, as window materials for infrared military devices, space vehicles, high-intensity lasers and optical communications...
2. Sapphire has high rigidity, high strength, high working temperature, abrasion resistance, corrosion resistance characteristics, so it is often used in harsh environments, such as boiler water gauge (high-temperature resistance), commodity bar code scanner, bearing and other precision manufacturing (wear resistance), coal, gas, well detection sensors and detector windows (anti-corrosion)...
3.Sapphire has the characteristics of electrical insulation, transparency, good thermal conductivity and high rigidity, so it can be used as the substrate material of integrated circuits, such as LED and microelectronic circuits, ultra-high-speed integrated circuit.

LOOK AT WHERE SAPPHIRE WAFER APPLIED
1. Semiconductor LED industry (MOCVD epitaxial GaN substrate)
In general, C-plane sapphire is needed in this area. R-plane or M-plane mainly used to grow non-polar/semi-polar plane epitaxial layers to improve the luminescence efficiency.
2. The growth of III-V or II-VI compound semiconductor.
3. Microelectronic IC applications especially Very High-Speed Integrated Circuit, SOS
Generally, it is a silicon heteroepitaxial deposition on R-plane sapphire.
4. Hybrid microelectronics
Hybrid microelectronics products are mainly HIC and MCM. It has high requirements on the substrate, while sapphire's characteristics such as stable dielectric constant and low dielectric loss make sapphire wafer the most commonly used substrate for HIC and the main substrate for MCM. Generally, the A-plane sapphire wafer is needed.
SAPPHIRE WAFER PROCESSING
At the very beginning, we have a crystal boule.
Crystal growing: Produce high-quality sapphire monocrystals via furnace.
Sapphire ingot processing: Drill out the ingot, Ground the ingot, Quality inspection.
Then we get the sapphire ingot.
Orientation: Position the ingot on the sawing machine.
Sawing: Cut the ingot into thin wafers.
Lapping: Lap the wafer to remove the scratched layer and improve its flatness.
Chamfer: Trim the edge of the wafer into an arc to improve the mechanical strength, to avoiding stress concentration.
Polishing: Reduce the surface roughness to reach the epitaxial wafer grade.
Cleaning: Remove dirt from the wafer surface.
Quality inspection: Inspect wafer with a high precision instrument to meet customer's requests.
Finally, we get the sapphire wafer.

Very laudable, but there doesn't seem to be much left from the old church.
