In essence, there is no difference, because the chip is the integrated circuit, the integrated circuit is made on the semiconductor material.

In the early years, researchers discovered semiconductors, from semiconductors to make transistors, and later due to scientific and technological progress, in a semiconductor material to make a lot of transistors, called integrated circuits, and later on the basis of integrated circuits more intensive increase thousands of thousands or even hundreds of millions of transistors, and then this thing called chips.
