The significance of silicon wafer heat treatment
- What will the resistivity change after heat treatmentBecause oxygen is the introduction of single crystal silicon at about 1400 DEG C, so the manufacturing process in general device temperature range (less than 1200 C), with the gap state of oxygen is in a saturated state, thermal cycling in the process of oxygen impurity in these devices due to the lower solid solubility will produce oxygen precipitation. Generally speaking, the higher the concentration of oxygen, the easier the oxygen precipitation is, the more oxygen precipitation is formed. On the contrary, the less oxygen precipitation. Especially when the oxygen concentration is less than a certain value (5 x 1017 / cm 3), the formation of oxygen precipitates is hardly observed.s
The problem of integrated circuit fabrication is how to realize the functions of capacitors, resistors and transistors on a single chip
- You connect the line in two holes on the silicon conductive layer in the middle, this is not a resistance capacitance resistance that integrated circuit in the senior middle school physics is not the kind of silicon wafer by resistance capacitance has made but I hope you can understand the function of course this is just the front-end integrated circuits
