SPBD
Silvaco's Process Database

SPDB is a comprehensive, high speed database manager designed to contain experimental and simulated doping profiles and recipes. With a user-friendly graphical user interface, it provides easy access to a wide range of experimental profiles. With over 6000 profiles gathered from leading worldwide sources, SPDB is the largest semiconductor process database commercially available. A user’s own profiles may be added and maintained within SPDB. User-defined or SILVACO supplied doping profiles are used as optimization targets for effective process simulator calibration.

Applications

  • Calibrate your process simulator by using Optimizer to fit simulation results to experimental data
  • Maintain your own profiles within SPDB in an open ASCII format
  • Export SIMS profiles to process and device simulators and DevEdit
  • Investigate novel process technologies including silicides, RTA, and implant species such as aluminum, germanium and antimony
  • Generate experimental matrices of time, temperature, dose and energy

The main screen is used to control searches, show the resulting set of matching experiments, and the composition of experiments.

 

Details of experiments are shown as a series of cards displaying information such as the processes involved and the date, author and origin of the experiment.

 

Lateral diffusion may be examined with SPDB’s two-dimensional profiles. Contours of arsenic are shown after a high dose implant and diffusion.

 

The SPDB Experiment Browser is used for convenient visualization of detailed information about the current experiment, including authors, publication source and date, all process steps, as well as analysis method (e.g. SIMS, SRP) and profile image.

Multiple Process Steps Search

One way to perform a search in SPDB is to define a series of process steps. In this example the search was for experiments with an implant of boron at a dose of 1e15 ions/cm2 and 60KeV implant energy into a silicon substrate. It was required that the implant be followed by a diffusion at a temperature of between 900 and 1000 degrees Centigrade for a period of 20 minutes. From the results of the implant and diffusion search three profiles were chosen.

The comparison is shown in the picture below.
