A semiconductor memory device having memory cells including a transistor and a trench type capacitor which are formed on a semiconductor substrate to cooperate with each other to store information. The device includes a trench having a bottom made of a first insulator disposed on the semiconductor substrate and a sidewall made of an epitaxial semiconductor layer which is epitaxially grown on the semiconductor substrate in a substantially vertical direction around the first insulator. The capacitor comprises an impurity diffused layer formed on the sidewall of the trench, a second insulator layer formed over thee impurity diffused layer, and a conductive layer opposite of the impurity diffused layer via the second insulator layer, with the transistor formed on the epitaxial semiconductor layer.

A semiconductor memory device having an excellent data holding characteristics because of a small leak current from a trench and a process for producing the same are disclosed. An SiO.sub.2 film 12 having an appropriate pattern is formed on a P type silicon substrate 11. Trenches 14 are relatively formed on the SiO.sub.2 film 12 by selectively growing a P type epitaxial layer 13 on the silicon substrate 11 using the SiO.sub.2 film 12 as a mask. An N type layer 23 acting as an electrode of a capacitor 27 is formed on the inner wall of the trench 14 by the oblique ion implantation of impurities 22 thereto. A polycrystalline silicon film 25 acting as an opposite electrode of the capacitor 27 is formed on an ONO film 24 so that the ONO film 24 is disposed between the polysilicon film 25 and the SiO.sub.2 film. The semiconductor memory device which is produced by this method without etching to form the trenches 14 has a fewer crystal defects in the epitaxial layer 13 around the trenches 14. Accordingly, the data holding characteristics are improved since the leak current from the trenches 14 becomes less. As a result of this, higher density integration is possible since the device can be made with less capacitance of capacitors.
