Multi-zone platen temperature control
A system and method for etching workpieces in a uniform manner are disclosed. The system includes a semiconductor processing system that generates a ribbon ion beam, and a workpiece holder that scans the workpiece through the ribbon ion beam. The workpiece holder includes a plurality of independently controlled thermal zones so that the temperature of different regions of the workpiece may be separately controlled. In certain embodiments, etch rate uniformity may be a function of distance from the center of the workpiece, also referred to as radial non-uniformity. Further, when the workpiece is scanned, there may also be etch rate uniformity issues in the translated direction, referred to as linear non-uniformity. The present workpiece holder comprises a plurality of independently controlled thermal zones to compensate for both radial and linear etch rate non-uniformity.
METROLOGY DEVICE, SYSTEM AND METHOD
A MEMS hotplate is used as a test substrate for characterizing a temperature-dependent fabrication process. According to a variant, an array of MEMS hotplates is used to provide multiple test substrates which can be simultaneously heated to different temperatures to provide multiple different temperature-dependent characterizations of the process.
METHOD AND SYSTEM FOR POSITIONING AND TRANSFERRING A SAMPLE
A system for positioning a sample in a charged particle apparatus (CPA) or an X-ray photoelectron spectroscopy (XPS) system includes a sample carrier coupled to a stage inside the vacuum chamber of the CPA or XPS system. The system allows transferring of the sample carrier among multiple CPAs, XPS systems and glove boxes in inert gas or in vacuum. The sample carrier is releasably coupled with the stage in the vacuum chamber of the CPA or the XPS. Multiple electrodes in a sample area of the sample carrier are electrically connectable with the stage by multiple spring contacts between the sample carrier and the stage.
Electron microscope having a carrier
An electronic microscope includes a carrier, a first driving unit, a flow-buffer unit and an electron source. The carrier carries a sample. The first driving unit drives a first fluid to flow along a first flow path, wherein the first flow path passes through the sample. The flow-buffer unit is disposed on the first flow path to perform buffering on the first fluid, wherein the first fluid flows through the flow-buffer unit and the carrier in sequence. The electron source provides an electron beam to the sample.
THERMAL DRIFT CORRECTION BASED ON THERMAL MODELING
The present invention relates to a method to reduce drift of a sample and/or its image in a microscopy system, wherein the method comprises determining an expected thermal drift of the sample, and compensating for the drift of the sample and/or its image based upon the expected thermal drift. The present invention also relates to a corresponding microscopy system and a computer program product to perform the method according to the present invention.
