Принадлежит:

The invention provides a shallow trench isolation (STI) structure preparation method, at least comprising the steps of: providing a semiconductor substrate, and etching the semiconductor substrate to form trenches in the semiconductor substrate; providing a reaction chamber, into which Ar gas is inputted as sputtering gas, and ionizing the Ar gas; placing the semiconductor substrate in the reaction chamber to perform preheating treatment; and filling insulating materials in the trenches so as to form an STI structure. According to the invention, in a semiconductor substrate preheating phase, Ar gas is employed as plasma source gas to replace O2 of the traditional process, thereby preventing the surfaces of the trenches of the semiconductor substrate in the preheating phase from being oxidized and corroded by O plasmas, reducing device leak current, preventing a device from isolation failure, and improving device reliability. In addition, Ar plasmas can improve the dissociation effect of ...

Shallow slot isolation structure manufacturing method

Номер: CN103871880A
Автор: ZHANG YU, HE HAIJIE, SHAN WEIZHONG, ZHAO HONGBO
Принадлежит:

The invention discloses a shallow slot isolation structure manufacturing method. An STI slot is filled by repeatedly carrying out steps in which a silicon dioxide layer is firstly deposited and then dry etching is carried out so as to obtain an STI structure. Fluorine and hydrogen ions are adopted in the case of dry etching; the fluorine ions and deposited silicon dioxide react to open the bottleneck structure of the STI slot side wall; the hydrogen ions carry out physical bombardment on the deposited silicon dioxide to remove the cap-shaped structures at two sides of the STI slot and level the bottom part of the STI slot. In the way, when the step in which the silicon dioxide layer is firstly deposited and then dry etching is carried out is executed each time, the obtained STI slot filling structure does not form cap-shaped structures at two sides of the STI structure, the bottleneck structure of the STI slot side wall is also removed, and the STI slot forms an STI structure large in the ...
