摘要： Pitch multiplied and non-pitch multiplied features of an integrated circuit, e.g., features in the array, interface and periphery areas of the integrated circuit, are formed by processing a substrate through a mask. The mask is formed by patterning a photoresist layer which simultaneously defines mask elements corresponding to features in the array, interface and periphery areas of the integrated circuit. The pattern is transferred to an amorphous carbon layer. Sidewall spacers are formed on the sidewalls of the patterned amorphous carbon layer. A layer of protective material is deposited and then patterned to expose mask elements in the array region and in selected parts of the interface or periphery areas. Amorphous carbon in the array region or other exposed parts is removed, thereby leaving a pattern including free-standing, pitch multiplied spacers in the array region. The protective material is removed, leaving a pattern of pitch multiplied spacers in the array region and non-pitch multiplied mask elements in the interface and periphery areas. The pattern is transferred to a hard mask layer, through which an underlying substrate is etched.

摘要： A process may include forming a mask directly on and above a region selected as an initial semiconductor fin on a substrate and reducing the initial semiconductor fin forming a semiconductor fin that is laterally thinned from the initial semiconductor fin. The process may be carried out causing the mask to recede to a greater degree in the lateral direction than the vertical direction. In various embodiments, the process may include removing material from the fin semiconductor to achieve a thinned semiconductor fin, which has receded beneath the shadow of the laterally receded mask. Electronic devices may include the thinned semiconductor fin as part of a semiconductor device.

摘要： A process may include first etching a trench isolation dielectric through a dielectric hard mask that abuts the sidewall of a fin semiconductor. The first etch can be carried out to expose at least a portion of the sidewall, causing the dielectric hard mask to recede to a greater degree in the lateral direction than the vertical direction. The process may include second etching the fin semiconductor to achieve a thinned semiconductor fin, which has receded beneath the shadow of the laterally receded hard mask. The thinned semiconductor fin may have a characteristic dimension that can exceed photolithography limits. Electronic devices may include the thinned semiconductor fin as part of a field effect transistor.
