With the goal to make sapphire wafers more accessible and affordable to Indian and global customers, these wafers are being produced in the Oragadam facility in Tamil Nadu
Claiming to be India’s first semiconductor chips manufacturer, Polymatech Electronics recently introduced a range of high-quality sapphire substrates which includes two, three, and four-inch diameter sapphire wafers in the market. The recent augmentation of the company’s infrastructure has increased its ability to manufacture large-diameter sapphire wafers at scale. The company said that industries producing smartphones, large displays, traffic lights, HDTVs, tablets, netbooks, and light bulbs that leverage LEDs are set to benefit from its ability to produce larger wafers.
In response to the current high demand for 4-inch sapphire wafers in the lighting and consumer electronics industries in India, the company is focusing on their manufacturing with crystal orientation c side (0001), A-plane (11-20) and thickness of 430±15μm with GaN crystals. It is learnt that Polymatech also plans to scale up to make eight-inch diameter sapphire wafers in the future while maintaining the transparency of 200 to 7000 nm.
The company said that its upcoming facility in Krishnagiri, Tamil Nadu is set to take advantage of the location to further lower costs and bring extensive experience in polishing large-diameter sapphire wafers closer to the LED, consumer electronics, and general lighting manufacturers in Asia.
It is well-known that Sapphire can withstand high temperatures, erosion and thermal shock. That’s why sapphire substrates are extensively utilised in the production of compounds like Gallium Nitride (GaN), which are used in the manufacture of laser diodes and blue LEDs. Quoting Transparency Market Research, the press release mentioned that the sapphire substrate market is estimated to grow at a compound annual growth rate of 6% on a global scale between 2020-2030.
Boasting its affordability, the company believes that its ability to produce high-quality sapphire wafers is crucial in helping industries that use LEDs and require large volumes to support the consumer electronics and general lighting industry.
Calling Polymatech a top-notch R&D and engineering team that is making great strides in the development of high-quality sapphire including India’s first 4-inch diameter wafer, the president and CEO of the company, Eswara Rao Nandam, commented, “It takes unique technology with advanced processes to make high-quality, large-diameter sapphires at scale. The Polymatech team has built a specialised, end-to-end process to ensure the top quality of our full range of wafer products. As of now, our wafers are for captive consumption and we will supply them to the market later. Polymatech’s ability to produce larger sapphire wafers will be key to helping industries that make and use LEDs scale up to support the growth needed in general lighting and consumer electronics. It is also important for us that our customers are able to depend on us for uniform, particulate-free sapphire wafers as well as flat, stress-free wafers. High-quality sapphire wafers help our customers produce high-quality LED wafers at volumes to support the LED supply chain.”
Polymatech Electronics identifies as an Opto-Semiconductor chips manufacturer and advanced electronic materials provider that is engaged in developing, manufacturing and selling monocrystalline sapphire and other crystalline products for light-emitting diodes (LEDs), radio frequency integrated circuits (RFICs), blue laser diodes, optoelectronics and other optical applications.
