Title: Method for forming a active cell isolation layer of a semiconductor device
Inventor: SHIN HYEON SU
IPC: H01L21/762
Filed: 2002-12-30
Abstract: PURPOSE: A method for forming an isolation layer of a semiconductor device is provided to make an isolation layer elastically cope with a leakage current between corresponding active devices that the quantity of the leakage current increases remarkably due to high speed of active devices disposed in an active region by making the isolation layer additionally have an impurity reinforcing layer as well as an oxide layer as a series of an insulation reinforcing element. CONSTITUTION: A sacrificial layer pattern is formed in the active region of a semiconductor substrate(11) to expose an isolation region. A predetermined depth of the isolation region is etched to form a series of trenches(16) by using the sacrificial layer pattern as an etch mask. Impurities are implanted into the etched surface of the trench to form the impurity reinforcing layer(20). An oxide layer(21) is grown on the impurity reinforcing layer. An insulation layer is filled in the trench to cover the sacrificial layer pattern. A part of the sacrificial layer pattern and the insulation layer is eliminated to expose the active region.
