Mobile phone chipmaker Qualcomm Inc.’s proposed $47 billion acquisition of NXP Semiconductors NV has some significance besides being called the largest semiconductor deal in history.

The transaction is also the first major deal that M&A heavyweight Scott Barshay has advised on since leaving Cravath, Swaine & Moore in April to join Paul, Weiss, Rifkind, Wharton & Garrison. Barshay’s role on the deal represents the first time that Paul Weiss has advised Qualcomm, a San Diego-based producer of semiconductors and other equipment used in the telecommunications sector.
