Manufacturing method of an integrated chip
View Patent ↗A manufacturing method of an integrated chip. The integrated chip includes at least two devices with different functions. The method uses a first production line to form a first device on a semiconductor wafer and then uses a second production line to form a second device on the semiconductor wafer so as to complete the integrated chip.
1. A manufacturing method of an integrated chip including at least two devices with different functions, the method comprising:
forming a memory cell array on a semiconductor wafer by a memory factory; and
forming a logic circuit on the semiconductor wafer by a standard foundry so as to complete the integrated chip.
2. The method of claim 1 wherein the integrated chip is an embedded memory.
3. The method of claim 1 wherein the logic circuit comprises transistors of the logic circuit and metal lines.
4. The method of claim 1 wherein each of the memory factory and the standard foundry uses at least one photo mask to perform a photolithography process.
5. The method of claim 4 wherein the photo mask of the memory factory and the photo mask of the standard foundry collectively form an integral set of photo masks for manufacturing the integrated chip.
