Method for removing semiconductor fins using alternating masks
A mask set and method for forming FinFET semiconductor devices provides a complementary set of fin-cut masks that are used in DPT (double patterning technology) to remove fins from non-active areas of a semiconductor device, after the fins are formed. Adjacent fins, or adjacent groups of fins, are removed using pattern features from different ones of the multiple fin-cut masks.

Systems and methods of local focus error compensation for semiconductor processes
A system and method of compensating for local focus errors in a semiconductor process. The method includes providing a reticle and applying, at a first portion of the reticle, a step height based on an estimated local focus error for a first portion of a wafer corresponding to the first portion of the reticle. A multilayer coating is formed over the reticle and an absorber layer is formed over the multilayer coating. A photoresist is formed over the absorber layer. The photoresist is patterned, an etch is performed of the absorber layer and residual photoresist is removed.

Mask manufacturing equipment and mask manufacturing method
According to an embodiment, mask manufacturing equipment includes a detector, an irradiator, a calculator, and a controller. The detector detects positional deviation of a pattern formed on a mask substrate. The irradiator irradiates the mask substrate with laser light to form a heterogeneous layer that is expanded in volume in the mask substrate. The calculator calculates an area periphery irradiation condition under which the irradiator is caused to emit laser light to a peripheral area of the pattern on the basis of the positional deviation detected by the detector so that the pattern area is reduced by forming the heterogeneous layer in the peripheral area of the pattern. The controller controls the irradiator to form the heterogeneous layer in the peripheral area of the pattern according to the area periphery irradiation condition.
