The Commerce Department slapped the restriction on Fujian Jinhua Integrated Circuit Co Ltd amid allegations the firm stole intellectual property from Micron Technology Inc and on concerns the firm could flood the market with cheap chips.
Micron rose 1.9 percent, and helped the Philadelphia Semiconductor Index jump 2.63 percent, rebounding after hitting its lowest in over a year on Monday. The broader technology sector was up 0.18 percent.
Chip-gear makers also gained after KLA-Tencor Corp rose 6.6 percent on strong quarterly results and forecast, helped by strength in its memory business.
"There are investors who have wanted to own chipmakers but have been so fearful because of what happened last week," said Peter Kenny, senior market strategist at Global Markets Advisory Group, in New York.
"These players have been prudently on the sidelines but are now seeing an opportunity to gain exposure to semis."
Industrial stocks rose 0.85 percent, getting a boost after President Donald Trump said "a great deal" on trade can be struck with China.
But he also warned that billions of dollars worth of new tariffs are ready if a deal isn't possible. That echoed the essence of a Bloomberg report on Monday that sent Wall Street tumbling at close.
Tariffs and rising costs are among the factors that have spurred a slew of disappointing forecasts from major industrials, chipmakers and other companies, adding worries over slowing corporate growth to fears of faltering global expansion.
Traders have said the uncertainty over next week's mid-term elections has also been a factor for the recent volatility.
"Because the impact of the mid-term elections on equities is so poorly defined, we can see it elevating volatility, if not anything," Kenny said.

On the earnings front, Coca-Cola Co shares climbed 1.8 percent after beating quarterly sales estimates, while rival PepsiCo Inc dipped 0.1 percent.
But, Pfizer Inc reported worse-than-expected third quarter revenue and lowered the top end of its full-year sales forecast as generic competition and drug pricing pressure in the United States hurt its older drugs business.
