The shortage of semiconductor chips

     In November 18, 2016, a fire in the Diodes US wafer factory was a wet etching wafer manufacturing area for the factory. Because of the fire, all the products in the KFAB plant will be suspended. The main products involved in the accident are general material, two or three pole tube, or will cause the global two or three pole to be out of stock.

     The shortage in the first half of 2017 will be more serious, chip plants: priority fingerprint identification, camera chips and other two, triode chips will be squeezed. The shortage of chips is, in fact, limited by the lack of capacity in the foundry. Generally speaking, chip designers report the capacity to the chip Fab in advance, and the chip Fab designs the production plan according to the chip manufacturers.

     From the fingerprint identification chip and camera chip, this fingerprint recognition function and intelligent mobile phone dual camera function is a large quantity of hot spots, from this fingerprint identification chip shipments and camera chip shipments can be seen, it is reported that the camera chip and fingerprint identification chip also use the same wafer size specifications, but for TSMC, SMIC chip foundries, wafer profit camera, two triode chip industry is far less than the fingerprint identification chip industry, so in the current wafer tight capacity situation, fab is likely to give priority to supply the fingerprint identification chip industry, resulting in the camera, two, transistor chip industry shortage situation.
