RESUMO

The intent of the thesis. "A Contribution to Integrated Circuit Projects With GaAs MESFET", is to obtain a relationship between the Research on Devices laboratory (lPD) GaAs process and the integrated circuits develop using this process. The LPD develops integrated circuits using the "Rapid Thermal Diffusion of Sulphur in GaAs". The SPICE parameters of the GaAs devices (depletion transistors), made using this process, was extracted. A computer program was developed, that takes as input the carachteristics curves of a device and gives as output the SPICE parameters according to the Raytheon Model (Statz et aI.). This model is used in the SPICE3-D2 (and upgraded version) developed by UC-Berkeley. We have obtained the experimental characteristics curves fit with that of the medel with an errer les5 than 4%. We have, also written the technology file/design rules for MAGIC-6.3, for the LPD diffusion process. Using MAGIC we have developed a test chip ("chipteste") with devices and circuits. These devices will be used to extract parameters that will contribute to the fine tuning of the model and the LPD process.
