Q:Do you have the optical characterization data for this InGaN wafer? We want to know want wavelength it emits when excited optically. A PL spectrum would be perfect. Also, is the InGaN grown on any buffer layer? What is the uniformity of the Indium composition? Any In segregation or clusters?

Q:Our application will be making micro-pillar arrays based on the MQWs for high brightness LEDs and its wavelength tuning. So we do not really care the emission wavelength you provide but we will mind whether the process and emission wavelength would be consist between wafers in one pack as well as the uniformity in one wafer. No metal contact would be perfect as we will employ high temperature process in our application. Do you offer the wafer dicing service as well?

Float-Zone Mono-Crystalline Silicon

PAM-XIAMEN can offer float zone silicon wafer, which is obtained by Float Zone method. Monocrystalline silicon rods is got through float zone growth, and then process the monocrystalline silicon rods into silicon wafers, called float zone silicon wafers. Since the zone-melted silicon wafer is not in contact with the quartz crucible during the floating zone silicon process, the silicon material is in a suspended state. Thereby, it is less polluted during the process of floating zone melting of silicon. The carbon content and oxygen content are lower, the impurities are less, and the resistivity is higher. It is suitable for the manufacture of power devices and certain high-voltage electronic devices.

Test Wafer Monitor Wafer Dummy Wafer

As a dummy wafer manufacturer, PAM-XIAMEN offers silicone dummy wafer / test wafer / monitor wafer, which is used in a production device to improve safety in the beginning of production process and are used for delivery check and evaluation of process form. As dummy silicon wafers are often used for experiment and test, size and thickness thereof are important factors in most occasions. 100mm, 150mm, 200mm, or 300mm dummy wafer is available.

Photo Mask

PAM-XIAMEN Offers Photomasks

A photo mask is a thin coating of masking material supported by a thicker substrate, and the masking material absorbs light to varying degrees and can be patterned with a custom design. The pattern is used to modulate light and transfer the pattern through the process of photolithography which is the fundamental process used to build almost all of today’s digital devices.

Ge(Germanium) Single Crystals and Wafers

PAM-XIAMEN offers 2”, 3”, 4” and 6” germanium wafer, which is short for Ge wafer grown by VGF / LEC. Lightly doped P and N type Germanium wafer can be also used for Hall effect experiment. At room temperature, crystalline germanium is brittle and has little plasticity. Germanium has semiconductor properties. High-purity germanium is doped with trivalent elements (such as indium, gallium, boron) to obtain P-type germanium semiconductors; and pentavalent elements (such as antimony, arsenic, and phosphorus) are doped to obtain N-type germanium semiconductors. Germanium has good semiconductor properties, such as high electron mobility and high hole mobility.
