Title: Isolation region of semiconductor and its manufacture
Inventor: KURARENSU UONNSHIN TENGU
IPC: H01L21/76
Filed: 1988-09-27
Abstract: PURPOSE: To form an isolation trench between active devices through one time of lithography and, at the same time, to improve the immunity to radiation of the trench by forming sidewall oxide layers on the sidewalls of the trench by using a thermal deposition technique or chemical vapor deposition technique and selectively growing silicon from a semiconductor material containing an exposed silicon area. CONSTITUTION: After a pad oxide layer 10 and a nitride layer 14 are formed on a substrate 12, trench areas 16 in which active devices are to be formed are coated with a photoresist layer, and trenches 18 are left exposed. Then the trenches 18 are filled up by selectively growing silicon or epitaxy 28 in the trenches 19 by using the exposed bottom sections 24 of the trenches as the 'seeds'. Since the growth of the epitaxy 28 is selective, the epitaxy 28 only grows upward from the bottom sections 24 of the trenches and does not grow from the other material than silicon. Then the nitride layer 14 is removed by using an etchant and the first-formed oxide layer 10 is removed. Thus a trench isolation area 32 having a channel stop area 20 surrounding the epitaxy area 28, sidewall oxide layers 26, and a field oxide layer 30 is formed.

Abstract: PURPOSE:To prevent a gate from being damaged due to an electric stress by making smaller the reverse withstanding voltage of a P-N junction formed between a second conductivity type diffused layer and a substrate than a voltage applied to a gate electrode for damaging the insulation of a gate insulating film. CONSTITUTION:<11>B<+> is ion implanted from a contacting hole 29 to form a P<+> type diffused layer 30 in a substrate 21 under an N<+> type diffused layer 26. The impurity density of the layer 30 is so set that the reverse withstanding voltage between the layer 26 and the layer 30 is smaller than a voltage applied to a gate electrode for damaging the gate. As a result, when a polycrystalline Si film pattern 31 is charged up in an ion implanting step or a reactive ion etching step after the ion implanting step or a high voltage is applied to the layer 26, the layer 26 - the layer 30 become a protecting diode, and the breakdown of the P-N junction occurs earlier. Accordingly it can prevent a gate oxide film 23 from being damaged.
