Sapphire is a single crystal of alumina, and has outstanding characteristics such as
hardness, corrosion-resistance, and high thermal conductivity. Moreover, since it is transparent, it can be
used for semiconductor wafers and sensor covers, and its demonstrated strength makes it suitable for broad
uses under harsh environments, such as various laboratory visualization windows, and infrared transmission
windows.
It is also widely used for watch exteriors, and has been adopted for use in exterior parts of smartphones,
smart watches, and new product designs.
We respond to various requests regarding sapphire, such as size, thickness, polished finish, small-quantity
prototypes, and mass production.
We also take upsizing, thinness/thickness, planarization, etc. into consideration, so please do not hesitate
to ask.
| Classification | Examples | Size |
|---|---|---|
| For epi | Semiconductor wafer (LED, Electric device etc.) | 2", 4", 6", 8", etc. |
| For optical | Optical window, tramission window, sensor cover | Angular plate, round plate, various kinds by request |
| Thickness processing | Optical parts, heatsink etc. | t100μm, max |
| Thick plate | High durability parts, heat dissipating wafer | 10mm, 20mm, 30mm, etc. |
| Large plate | Large window for visualization, stage glass | We can consider larger size of plate such A4 size etc. |
