An EUV photoresist composition includes paramagnetic particles that are adapted to block EUV radiation. The magnetic manipulation of the paramagnetic particles within a deposited layer of EUV photoresist can beneficially impact focus control and the achievable line width roughness during subsequent photolithographic processing. A spin-coating apparatus for dispensing the EUV photoresist composition onto a substrate includes a plurality of concentric electromagnets located beneath the substrate that influence the distribution of the paramagnetic particles in the photoresist layer.

Uniformity control of metal-based photoresists

A method includes identifying a contamination region of a collector in a light source, positioning a subset of a plurality of movable light-blocking elements around a periphery of a circular aperture of the light source to compensate for the contamination region, and transmitting light from the light source through the circular aperture.

Radial lithographic source homogenizer

A method includes identifying a first contamination region of a collector of a light source and enabling a subset of a plurality of temperature control elements positioned on the collector to cause a second contamination region to be formed on the collector symmetric to the first contamination region.

Balancing collector contamination of a light source by selective deposition

At least one method, apparatus and system for providing capturing synchrotron radiation for a metrology tool, are disclosed. A beam using a first light emitting device is provided. The first light emitting device comprises a first electron path bend. A first synchrotron radiation is provided from the first electron path bend to a first metrology tool configured to perform a metrology inspection using the first synchrotron radiation.

Method, apparatus and system for using free-electron laser compatible EUV beam for semiconductor wafer metrology

A method includes forming a first conductive feature positioned in a first dielectric layer. A conductive polymer layer is formed above the first dielectric layer and the first conductive feature. The conductive polymer layer has a conductive path length. A second dielectric layer is formed above the first dielectric layer. A first via opening is formed in the second dielectric layer and the conductive polymer layer to expose the first conductive feature. A conductive via is formed in the first via opening. The conductive via contacts the first conductive feature and the conductive polymer layer.

Methods for receiving a high-energy EUV beam and distributing EUV sub-beams to photolithography scanners and the resulting device are disclosed. Embodiments include receiving a high-energy primary EUV beam at a primary splitting optical assembly; splitting the primary EUV beam into primary EUV sub-beams; reflecting the primary EUV sub-beams to beam-splitting optical arrays; splitting the primary EUV sub-beams into secondary EUV sub-beams; reflecting the secondary EUV sub-beams to EUV distribution optical arrays; and distributing simultaneously the secondary EUV sub-beams to scanners.

Method and device for splitting a high-power light beam to provide simultaneous sub-beams to photolithography scanners

At least one method, apparatus and system for providing an extreme ultraviolet beam for processing semiconductor wafers are disclosed. A level of the EUV beam is monitored. A determination is made as to whether the level of the EUV beam is below a predetermined level. In response to determining that the level of the EUV beam is below the predetermined level, a determination is made as to whether the output of at least one of the first or second laser devices has decreased from an initial level. The output of the at least one of the first or second laser devices is increased in response to determining that the output of at least one of the first or second laser devices has decreased from an initial level.
