One of Wall Street's favorite chipmakers has seen its value tumble as worker shortages and delays dent investor hype

The world's largest chipmaker, Taiwan Semiconductor Manufacturing, just saw its revenue drop for the first time in four years.

The company said Thursday that second-quarter revenue declined nearly 10% compared to the same time a year ago, and annual net profits dropped 23%.

Shares in Taiwan dropped more than 3%, and were down about 0.5% in US markets Friday. 

Unfortunately for TSMC — and the chip sector at large — this doesn't exactly come as a surprise.
