  • Publication number: 20230394210
    Abstract: An exemplary method for semiconductor device simulation includes receiving a device structure, generating a mesh for the device structure, simulating electrical behavior of the device structure using the mesh, and adaptively adjusting the mesh during the simulating. The adaptively adjusting the mesh includes performing a multi-level restriction-prolongation (MLRP) process that decreases and increases a resolution of the mesh. The semiconductor device simulation can be performed by a semiconductor simulation system that includes a central processing unit, a memory, and a hardware accelerator. The MLRP process is at least partially parallelized on the hardware accelerator, such as a GPU.

  • Publication number: 20230394642
    Abstract: The present disclosure provides a method for topography simulation of a physical structure under a topography-changing process. The method includes initializing a voxel mesh as a three-dimensional (3D) representation of the physical structure, generating a batch of particles, simulating a flight path of at least one of the particles with a ray-tracing method, identifying a voxel unit in the voxel mesh that intersects the flight path, determining a surface reaction between the one of the particles and the voxel unit, and adding an extra voxel unit adjacent to the voxel unit based on the determining of the surface reaction.

  • Publication number: 20230070928
    Abstract: A high throughput, efficient, and simplified unloading and packaging systems and methods for large-scale production of pharmaceutical units (104) using additive manufacturing. The systems and methods may unload, inspect, package, and trace pharmaceutical units, produced by an additive manufacturing system (900), that are not damaged or deformed. The unloading and packaging system can include one or more unloading and packaging devices (100). The unloading and packaging device can include a modular configuration having modules. Individual modules to be arranged in any relative order, at any location, and with any number in the unloading and packaging device. The flexibility of the modular configuration allows one or more modules to be removed or added at any given time due to, e.g., expansion, downsizing, module repair, module upgrades, etc. High throughput can be achieved by operating unloading and packaging devices independently.

  • Publication number: 20210351270
    Abstract: A method of manufacturing a p-type MOSFET includes depositing a channel material to form a channel region, forming a source region and a drain region on each side of the channel region along a first direction, depositing a gate oxide layer on the channel region along a second direction crossing the first direction, and depositing a gate electrode on the gate oxide. The channel material includes a group IV element or III-V semiconductor compound and have a diamond or zincblende cubic crystal structure. A <001> direction of the crystal structure is parallel to the second direction. Two adjacent atoms on an out-most atomic layer of the channel region along the first direction are connected to each other via a single intervening atom, and an interface between the gate oxide layer and the channel region has a surface roughness of 1 angstrom or lower.
