Looking back on semiconductor manufacturing stocks' Q4 earnings, we examine this quarter's best and worst performers, including Amkor (NASDAQ:AMKR) and its peers.

The semiconductor industry is driven by demand for advanced electronic products like smartphones, PCs, servers, and data storage. The need for technologies like artificial intelligence, 5G networks, and smart cars is also creating the next wave of growth for the industry. Keeping up with this dynamism requires new tools that can design, fabricate, and test chips at ever smaller sizes and more complex architectures, creating a dire need for semiconductor capital manufacturing equipment.
