Title: Process of preventing the edge-angle effects
Inventor: CHEN JR-RUNG
IPC: H01L21/76
Filed: 1998-04-16
Granted: 2000-04-11
Abstract: This invention provides a new type of process for forming the shallow trench isolation region with the capability of preventing the edge-angle effects. This new type of process does not need to grow the local oxidation of silicon first in the furnace tube. In addition, the gate oxide thinning problem occurred in the conventional etching of the local oxide to form the trench is solved as the sidewall spacer is inside the trench. The process of this invention uses the silicon nitride layer as a mask to define the trench region. At first, a slightly over-etching down to the interior of silicon substrate is proceeded to form the trench. The sidewall spacer is then formed sequentially inside the trench. This sidewall spacer is also used as the hard mask for the following etching of the silicon layer in the trench. Since part of the sidewall spacer is built in the silicon layer, the shallow trench isolation region with the capability of preventing the edge-angle effects is obtained after the sidewall spacer is removed.

By using the lens system 7, the leaked light can be imaged on the CCD6 and image processed by processing device 12. In the total dark background, the scratched portion shows the brightness of some visible lines and dots, so that the tiny scratches can be detected from the detected image.
