    • A manufacturing method for a vertical transistor of random-access memory, having the steps of: defining an active region on a semiconductor substrate; forming a shallow trench isolation structure outside of the active region; etching the active region and forming a gate dielectric layer and a positioning gate thereon, forming a word line perpendicular to the positioning gate; forming spacing layers on the outer surfaces of the word line; implanting ions to the formed structure in forming an n-type and a p-type region on opposite sides of the word line with the active region; forming an n-type and a p-type floating body respectively on the n-type and p-type region; forming a source line perpendicular to the word line and connecting to the n-type floating body; forming a bit line perpendicular to the source line and connecting to the p-type floating body. Hence, a vertical transistor with steady threshold voltage is achieved.
