Which of these Star Wars films feature the death of Yoda?

I love the story that tells how the studio had so little faith in the original "Star Wars" movie that they allowed George Lucas to keep the merchandising rights. More than 300 million Star Wars action figures have been sold worldwide. Lucas has made far more money from action figures and games than on all the movies. Today, he is Hollywood's richest man, worth a cool $5.5 billion.
