Stocks of Taiwanese pattern sapphire substrate (PSS) providers, including Crystalwise, Rigitech Microelectronics, and Acme Electronics, lately witness a noticeable hike.

Following the launch of the sapphire covered Apple Watch, Tawanese sapphire makers share value have soared over the last week. As the LED industry enters a peak season, sapphire industry shares value have reached new record high, reported Apple Daily.

Taiwanese sapphire manufacturers Rigidtech Microelectronics (Rigidtech) and Aceplux Optotech have seen revenue more than double during May and June 2014, according to a CNYes.com report. The two companies benefited from soaring LED lighting demands that have led to rising Patterned Sapphire Substrate (PSS) revenue.

LED upstream key material PSS is in short supply with demands unable to be met. With supply unable to meet demands from LED manufacturers last year, production capacity is lacking by 50 percent, according to Economic Daily News. This had lead to a rise in price of around 5 percent for sapphire ingot, polished wafers, and PSS in March. Manufacturers including Crystalwise, Ridgetech, Aceplux Optotech, and Crystal Applied Technology are anticipated to benefit. PSS industry insiders are optimistic towards March operations.
