The large stars.
Inside stars nuclear fusion occur. Hydrogen fuse into helium.Helium fuse to form carbon and so on. The last one is the iron. After these element are dispersed, they become the building block of planets.

They are "cooked" in stars, and heavier elements are formed by atomic fusion reactions. Large stars can form heavy elements, and when they turn supernova and explode, these elements are dispersed throughout the universe. The sun is not large enough to form the heaviest elements and will not become a nova.
