| >> Synthetic Quartz |
Advanced Materials Division |
Synthetic quartz is produced from oxygen, hydrogen and silicon compound(s). The Shin-Etsu Group achieved success being the first mass-producer of synthetic quartz with a higher purity than natural quartz. It is utilized in optical fibers, photomask substrates for LSI and stepper lenses used for inscribing semiconductor circuitry, large-sized photomask substrates for liquid crystal display (LCD) panels, etc. It is supporting development of a highly informationalized society, and has become an indispensable material to the IT industry.

| Optical fiber preforms with diameters of 170 mm and lengths of 2,000 mm. Each will become roughly 3,000 km of optical fiber. |
Synthetic quartz photomask substrates for LSI and LCD. |
|
|
Optical fiber is made using synthetic quartz as a key raw material. |
|
 |
Liquid crystal display are noteworthy as a space saver in offices and homes. What has made the larger sizes possible are Shin-Etsu Chemical's large-sized photomask substrates for LCD. |

| >> Oxide Single Crystals (Lithium Tantalate: LT) |
Advanced Materials Division |
Lithium tantalate (LT) is used in mobile communication devices ,such as TV and VTR tuners,as SAW devices, which screens electromagnetic waves and picks up only those of specific frequencies. Oxide single crystals are contributing these days to the popularization of cellular telephones, and thus play a large role in the modern information society.

| >>Pyrolytic Boron Nitride (PBN) |
Advanced Materials Division |
PBN is a high-purity ceramic with excellent chemical resistance and strength at high temperatures. It was Shin-Etsu Chemical who succeeded at producing PBN domestically for the first time in Japan. PBN is used in crucibles for producing compound semiconductors and molecular-beam epitaxy, which make use of its characteristics. The extent of potential uses of PBN is expanding, such as high functional PG/PBN heaters for semiconductor field and CIGS based thin film for photovoltaic power generation.

|
| >>High-Purity Silicon Parts |
Advanced Materials Division |
High-purity silicon parts are used in the electrodes in the upper part of
the etching equipment used in the semiconductor production process and in
the focus ring which ensures uniformity of etching on the periphery of the
wafer. Shin-Etsu Chemical handles the entire production process; from
silicon ingots to silicon parts, and provides a steady supply of large
diameter, high purity products.

>>High-Purity Organometallics
(TMG, TEG, TMI, TMA, DMZ, DEZ, TBP) |
Advanced Materials Division |
Shin-Etsu High-Purity Organometallics are the highest purity metalorganic precursors, which are used to deposit compound semiconductor thin films by MOCVD (metal organic chemical vapor deposition). These materials are a vital component of the compound semiconductor film technologies and these organometallic products are used in a wide range of electronic and optoelectronic devices, such as high-brightness LEDs, laser diodes, and high-speed electronic devices.
