1. Deposition: Deposit thin film layers on the surface of semiconductor materials, such as chemical vapor deposition (CVD) and physical vapor deposition (PVD).

2. Etching: Use chemical or physical methods to remove unwanted materials on the surface, such as wet etching and dry etching.

3. Photolithography: Use photoresist and mask to map the pattern onto the chip surface to define the pattern of the circuit.

4. Annealing: Change the lattice structure and properties of materials through the process of heating and cooling.

5. Doping: Introducing impurities into the material to change its electronic properties, such as n-type doping and p-type doping.

6. Metallization: Add a metal layer on the chip for current flow, connection and wiring.

7. Cleaning: Remove impurities and pollutants through chemical solutions or physical processes to maintain the purity of the chip.

8. Alkaline Cleaning: Use alkaline solution to remove organic and inorganic residues on the surface of the material.

9. Contact Exposure: The photoresist is directly contacted with the mask to transfer the pattern.

10. Masking Layer: A chemical or physical layer for protection or selective exposure.

11. Annealing: Relieve stress by heating and cooling, improve the quality of lattice structure and adjust electronic properties.

12. Hetero junction: A structure composed of different materials with different energy band structures and electronic properties.

13. Electron Beam Lithography: Use electron beams to draw patterns for high-resolution lithography.

14. CMP (Chemical Mechanical Polishing): A process for leveling and polishing surfaces through chemical and mechanical action.
