Title: Short channel non-self aligned VMOS field effect transistor
Inventor: WOLLESEN DONALD L
IPC: H01L29/10
Filed: 1997-05-13
Granted: 2002-09-11
Abstract: A field effect transistor with a trench or groove gate having V-shaped walls is formed in a semiconductor substrate and a gate oxide is grown on the V-shaped walls to the surface of substrate and filled with a gate electrode material, such a polysilicon. Preferably, the bottom of the V-shaped walls are rounded either before or after the gate oxide is grown. Source/drain impurities either are diffused or implanted into the areas of the substrate on both sides of the surface oxide of the V-shaped gate. Contacts are made to the source and drain within the field isolation, and to the gate outside and on the field isolation to complete the structure. The resultant FET structure comprises a non-self aligned V-shaped gate having conventional source and drain surrounded by field isolation but with an effective channel length (Len) of less than about one-half of the surface width of the gate, of which the surface portion extends on to the field isolation. Preferably, the bottom of the V-shaped gate is rounded and concave. Because of the V-shaped structure of the gate, the effective saturated length of the channel with drain voltage applied only extends from the edge of the source to just prior to the tip of the V-shaped structure in the interior of the semiconductor substrate. The drain side of the V-shaped structure becomes a depletion region due to the applied drain voltage. Due to this characteristic of such a structure, the surface width of the gate can be, for example, two or more times the distance of the desired channel length thereby permitting conventional lithography to be used to define the gate lengths much shorter than the lithographic limit.
