    摘要: For lithographically manufacturing a device with a very high density, a design mask pattern (120) is distributed on a number of sub-patterns (120a, 120b, 120c) by means of a new method. The sub-patterns do not comprise “forbidden” structures (135) and can be transferred by conventional apparatus to a substrate layer to be patterned. For the transfer, a new stack of layers is used, which comprise a pair of a processing layer (22; 26) and an inorganic anti-reflection layer (24; 28) for each sub-pattern. After a first processing layer (26) has been patterned with a first sub-pattern, it is coated with a new resist layer (30) which is exposed with a second sub-pattern, and a second processing layer (22) under the first processing layer is processed with the second sub-pattern.

    摘要: A method is described for imaging, by means of projection radiation, a phase-shifting mask pattern on a substrate for the purpose of configuring device features in the substrate. By using a mask pattern comprising mask features constituted by a phase transition (22) and two sub-resolution assist features (40,41), arranged symmetrically with respect to the phase transition and having a mutual distance (p), device features having a wide variety of widths can be obtained by varying only the mutual distance.

    摘要: A method of forming a pattern in at least one device layer in or on a substrate comprises: coating the device layer with a first photoresist layer; exposing the first photoresist using a first mask; developing the first photoresist layer to form a first pattern on the substrate; coating the substrate with a protection layer; treating the protection layer to cause a change therein where it is in contact with the first photoresist, to render the changed protection layer substantially immune to a subsequent exposure and/or developing step; coating the substrate with a second photoresist layer; exposing the second photoresist layer using a second mask; and developing the second photoresist layer to form a second pattern on the substrate without significantly affecting the first pattern in the first photoresist layer, wherein the first and second patterns together define interspersed features having a spatial frequency greater than that of the features defined in each of the first and second patterns separately. The process has particular utility in defining source, drain and fin features of finFET devices with a smaller feature size than otherwise achievable with the prevailing lithography tools.
