Last month’s earthquake in Japan is impacting the production of complementary metal-oxide semiconductor (CMOS) image sensors at two facilities in the country, affecting the manufacture and distribution of cameras for cell phones, IHS iSuppli research has determined.
Toshiba Corp.’s Iwate Image Sensor fab, which produces logic chips and CMOS image sensors for mobile phone cameras, was shut down. Likewise, delivery was delayed from Sony Corp.’s CMOS image sensors to cell phone original equipment manufacturers.
Toshiba in 2010 was the world’s fifth-largest supplier of handset image sensors with 13.1 percent share of global revenue, according to a preliminary IHS iSuppli estimate. Sony ranked sixth with 3.9 percent share. Together, the companies accounted last year for 17 percent of the global handset digital camera image sensor revenue.
While CMOS sensor production and distribution has been impacted, supplies of the major alternative image sensor technology—CCDs—appear to be unaffected, at least for the near term. The global CCD market is dominated by Japanese suppliers including Sony, Panasonic Corp., Fujifilm, Sharp Corp. and Toshiba.
Because of their higher image quality, CCDs are commonly employed in digital still cameras. In contrast, the lower-cost CMOS sensors predominately are used in cell phones and other devices where the camera is secondary to other functions.
Taiwan-based digital camera makers Altek Corp. and Ability Enterprise, which contract-manufacture products for major Japanese brand names, said they were not experiencing any shortages in near-term CCD supply from Japan. Ability now sources about 90 percent of its CCD components from Sony, while Altek buys between 70 and 80 percent of those parts from Sharp. Sharp’s CCD plants in Japan are far from the worst-hit zones, while Sony’s CCD plants are located in Thailand.
Because of this, CCD supply in the future should not face any immediate supply issues. The situation may change over the long term, however, as CCD makers could experience challenges with their own upstream material suppliers and encounter problems with transportation and power.
Given the impact of the quake, Japanese-based digital camera brands Panasonic, Canon and Nikon have had to close down some of their high-end production lines for digital still cameras in Japan. But because the lower-end consumer models of those companies are primarily manufactured at plants in China and Thailand or outsourced to Taiwan-based makers, the earthquake is not expected to have a significant impact on those segments, the two companies noted.
