Patent ID: 7902074

Claim:
A method for fabricating a semiconductor device, the method comprising: patterning a layer of photoresist material to form a plurality of mandrels formed of photoresist in a device array region; depositing an oxide material on the plurality of mandrels and over a device peripheral region at a deposition temperature of about 200° C. or less; forming a pattern of photoresist material over the oxide material in the device peripheral region; anisotropically etching the oxide material from exposed horizontal surfaces in the device array region, thereby forming spacers from the oxide material, wherein the pattern of the photoresist material extends over the ends of the spacers; transferring a pattern defined by the spacers to an underlying material, wherein the pattern of the photoresist material blocks transfer of the ends of the spacers to the underlying material; and selectively etching photoresist material from the device array region and from the device peripheral region.
