Abstract:
Methods and systems for direct atomic layer etching and deposition on or in a substrate using charged particle beams. Electrostatically-deflected charged particle beam columns can be targeted in direct dependence on the design layout database to perform atomic layer etch and atomic layer deposition, expressing pattern with selected 3D-structure. Reducing the number of process steps in patterned atomic layer etch and deposition reduces manufacturing cycle time and increases yield by lowering the probability of defect introduction. Local gas and photon injectors and detectors are local to corresponding columns, and support superior, highly-configurable process execution and control.
Abstract:
Methods, systems and devices for using different encryption keys written into interconnects of different functional blocks in different integrated circuits to securely encrypt and authenticate firmware, data, instructions and other messages transmitted among said functional blocks; and methods, systems and devices to obfuscate encryption keys to significantly increase the time and resources required to compromise those keys, ensuring encrypted data is only decrypted by authorized functional blocks, applications or users. Unique keys, small enough not to impact substrate surface area available for other device functions, can be written by charged particle beams such that multiple (or each of) functional blocks has a corresponding key unique within an IC and across a line of ICs and so that access to said keys is as limited (or nonexistent) as desired. Circuits embodying key bits can also be distributed throughout ICs and across layers, uniquely to individual functional blocks in individual ICs, to obfuscate patterns implementing keys and thereby raising time and resource cost to reverse engineer keys to prohibitive levels.
Abstract:
Methods, tools and systems for patterning of substrates using charged particle beams without photomasks, without a resist layer, using multiple different processes (different chemistry processes and/or different ones of material deposition, removal and/or modification) in the same vacuum space, wherein said processes are performed independently (without cross-interference) and simultaneously. As a result, the number of process steps can be reduced and some lithography steps can be eliminated, reducing manufacturing cycle time and increasing yield by lowering the probability of defect introduction. Also, because such processes are resist-less, layer-to-layer registration and other column control processes can be performed by imaging previous-layer features local to (or in contact with) features to be written in a next layer as designated by the design layout database.
Abstract:
Methods, devices and systems for targeted, maskless modification of material on or in a substrate using charged particle beams. Electrostatically-deflected charged particle beam columns can be targeted in direct dependence on the design layout database to perform direct and knock-on ion implantation, producing patterned material modifications with selected chemical and 3D-structural profiles. The number of required process steps is reduced, reducing manufacturing cycle time and increasing yield by lowering the probability of defect introduction. Local gas and photon injectors and detectors are local to corresponding individual columns, and support superior, highly-configurable process execution and control. Targeted implantation can be used to prepare the substrate for patterned blanket etch; patterned ALD can be used to prepare the substrate for patterned blanket deposition; neither process requiring photomasks or resist. Arrays of highly configurable beam columns can also be used to perform both positive and negative tone lithography in a single pass.
Abstract:
Methods, devices and systems for patterning of substrates using charged particle beams without photomasks and without a resist layer. Material can be deposited onto a substrate, as directed by a design layout database, localized to positions targeted by multiple, matched charged particle beam columns. Reducing the number of process steps, and eliminating lithography steps, in localized material addition has the dual benefit of reducing manufacturing cycle time and increasing yield by lowering the probability of defect introduction. Furthermore, highly localized, precision material deposition allows for controlled variation of deposition rate and enables creation of 3D structures. Local gas injectors and detectors, and local photon injectors and detectors, are local to corresponding ones of the columns, and can be used to facilitate rapid, accurate, targeted, highly configurable substrate processing, advantageously using large arrays of said beam columns.
