A GaN transistor with polysilicon layers for creating additional components for an integrated circuit. Tetraalkyl ammonium fluoride, ammonium fluoride or the like is used as hydracid fluoride salt. One variation generally comprises a handle portion with an elongate outer jacket extending from the handle portion. Further, this method consists in using the percentage reserve of the frame, providing a quality of service based on that required by the user equipment and supplying a criterion for dynamically assigning the packets sent to each user equipment in the frame, grouping or dividing them.
