CASA Engineering is dedicated to designing strategies to improve quality of materials. CASA achieves this by controlling defect formation in materials. Atomistic simulations assist in understanding nucleation of defects in materials.
Performance of products depends on microscopic structure and properties of materials. Controlling structural defects in materials is an essential part of materials design and quality control effort. We investigate nucleation of defects in materials with a software package "ADESH" (Atomistic DEfect Simulation Handler). The results assist in designing processing strategies to control defect densities in materials.
Case Studies:

• Void Formation in Metal Interconnects
• Formation and Migration of Dislocations Near Trenches Near Devices
• Controlling stresses with alloying
• Formation of Defects in Thin Films
• Crack Nucleation and Growth

Based on above case studies, the need for "Microscopic Monitoring" (e.g. stress measurements, strain distribution, simulations etc.) during production is obvious.

ADESH simulates atomic structures (all fourteen Bravais Lattices) and minimizes energies of defect configurations (vacancies or impurities, dislocations, grain boundaries, stacking faults, hetero-structures, voids, precipitates etc) with various numerical techniques (Static, Monte-Carlo, Simulated Annealing etc.). ADESH is currently used in five countries for:
(a) Design and Development of Materials
(b) "Reverse Engineering": Backtracking Failure of Finished Products.

• Please say a few words about your project or problems here. We will listen. We can then discuss how CASA can be of assistance to you.
  
  
• We give on sight ADESH demonstrations and informative talks on "Defect Control, Process Design and Materials Development".
  Contact us to know more details.
  
  
• Design Processing Steps to Control Defect Formation in Materials We work in a variety of industrial settings: Semiconductor, Aerospace, ceramic etc. We have extensive experience working with metals, semiconducting materials and ionic crystals.
  
  
• We will get you started on your atomistic program. If you are experienced at using atomistic simulations for practical applications, we will work with you as you include our software into your projects. We gaurantee that you will save time, energy, effort and money by associating with us.
