METHOD OF MANUFACTURING A LOCOS SEMICONDUCTOR DEVICE |
摘要 |
A method of manufacturing LOCOS transistors in which base doping, emitter doping and emitter metallization are provided via the same aperture. Problems at the edge of the sunken oxide are eliminated by a two-stage doping technique so that the channel stopper diffusion in the epitaxial layer may be omitted, which presents particular advantages in the manufacture of I2L devices. |
