Qualcomm, which supplies cellphone chips, sees NXP Semiconductors as its entry into the lucrative autonomous-vehicle industry. The deal would also move Qualcomm further into the chip-making process.
The company designs and sells mobile phone chips, which are used in most of the world's leading smartphones including Apple's iPhone, but the products themselves are manufactured by Taiwan Semiconductor Manufacturing, which also makes products for other chip designers.
