titleOfInvention | Well Forming Method of Semiconductor Device |
abstract | The present invention relates to a method for forming a well of a semiconductor device, and more particularly, to a method for forming a well of a semiconductor device suitable for critically forming a boundary between wells. Such a well forming method of a semiconductor device may include preparing a semiconductor substrate, forming an insulating film on the semiconductor substrate, forming a photoreactive material layer on the insulating film, and selectively exposing the photoreactive material layer. Forming a hole by dry etching the photoreactive material layer of the unexposed portion; oxidizing the photoreactive material layer to form an oxide film; and forming a first conductive well in the semiconductor substrate under the hole. Forming a photoresist film, selectively forming a photoresist film in the hole, removing the oxide film, and forming a second conductivity type well in the semiconductor substrate under both sides of the photoresist film. |
