Semiconductors are an important key to modern technology, and anyone who has even vaguely kept up with news in the post-pandemic world knows that a lack of chips can bring whole supply chains to their knees. The pressure on the semiconductor manufacturers to churn out ever more chips can be a lot, but it has driven up the value of those businesses. That makes semiconductor stocks a great addition to many portfolios in 2022.

It's not only pandemic pressures that have driven up semiconductor stock values in recent years. The technological world literally runs on chips. They're in everything from iPhones to electric vehicles. They're important to almost every industry, including staples such as health care, computing, defense, clean energy, and communications.

Those are facts that won't change much anytime in the near future. And with a growing and stable demand for chips, investors can be bullish on established semiconductor stocks. Here are a few that may be worth keeping in mind.
