A system and a method directed to a monitoring system of semiconductor processing chambers is provided. In particular, monitoring of any chemical formation on a chamber and a wafer of a semiconductor processing chamber using in-situ laser induced fluorescence is provided. The monitoring system and method detect issues before they become a problem for the semiconductor processing chambers by providing diagnosis on chamber health and mechanisms for associated process shifts with a faster turnaround time.

In-situ fluorescence-based chamber and wafer monitoring

A system and method for performing corrective processing of a workpiece is described. The system and method includes receiving a first set of parametric data from a first source that diagnostically relates to at least a first portion of a microelectronic workpiece, and receiving a second set of parametric data from a second source different than the first source that diagnostically relates to at least a second portion of the microelectronic workpiece. Thereafter, a corrective process is generated, and a target region of the microelectronic workpiece is processed by applying the corrective process to the target region using a combination of the first set of parametric data and the second set of parametric data.

Hybrid corrective processing system and method

A system and method for performing location specific processing of a workpiece is described. The method includes placing a microelectronic workpiece in a beam processing system, selecting a beam scan size for a beam scan pattern that is smaller than a dimension of the microelectronic workpiece, generating a processing beam, and processing a target region of the microelectronic workpiece by irradiating the processing beam along the beam scan pattern onto the target region within the beam scan size selected for processing the microelectronic workpiece.

Method for high throughput using beam scan size and beam position in gas cluster ion beam processing system

A method for correcting a surface profile on a substrate is described. In particular, the method includes receiving a substrate having a heterogeneous layer composed of a first material and a second material, wherein the heterogeneous layer has an initial upper surface exposing the first material and the second material, and defining a first surface profile across the substrate. The method further includes setting a target surface profile for the heterogeneous layer, selectively removing at least a portion of the first material using a gas cluster ion beam (GCIB) etching process, and recessing the first material beneath the second material, and thereafter, selectively removing at least a portion of the second material to achieve a final upper surface exposing the first material and the second material, and defining a second surface profile, wherein the second surface profile is within a pre-determined tolerance of the target surface profile.

Method of surface profile correction using gas cluster ion beam

Disclosed are an apparatus, system, and method for scanning a substrate or other workpiece through a gas-cluster ion beam (GCIB), or any other type of ion beam. The workpiece scanning apparatus is configured to receive and hold a substrate for irradiation by the GCIB and to scan it through the GCIB in two directions using two movements: a reciprocating fast-scan movement, and a slow-scan movement. The slow-scan movement is actuated using a servo motor and a belt drive system, the belt drive system being configured to reduce the failure rate of the workpiece scanning apparatus.

Multi-step location specific process for substrate edge profile correction for GCIB system

A method of modifying an upper layer of a workpiece using a gas cluster ion beam (GCIB) is described. The method includes collecting parametric data relating to an upper layer of a workpiece, and determining a predicted systematic error response for applying a GCIB to the upper layer to alter an initial profile of a measured attribute by using the parametric data. Additionally, the method includes identifying a target profile of the measured attribute, directing the GCIB toward the upper layer of the workpiece, and spatially modulating an applied property of the GCIB, based at least in part on the predicted systematic error response and the parametric data, as a function of position on the upper layer of the workpiece to achieve the target profile of the measured attribute.
