Abstract: Methods of forming an integrated circuit device include forming an interlayer dielectric layer on a first surface of a semiconductor substrate and then forming an interconnect hole that extends through the interlayer dielectric layer and into the semiconductor substrate. A first sidewall spacer layer is formed on a sidewall of the interconnect hole. The semiconductor substrate at a bottom of the interconnect hole is isotropically etched to define an undercut recess in the semiconductor substrate. This etching step is performed using the first sidewall spacer layer as an etching mask. The interconnect hole and the uncut recess are then filled with a through-via electrode. A second surface of the semiconductor substrate is removed for a sufficient duration to expose the uncut recess containing the through-via electrode.

Abstract: A method for controlling data transmission rate in order to save waste of resources due to Non-Line Of Sight (NLOS) region when a mobile terminal passes through the NLOS region in an interactive satellite communication system is disclosed. The method includes the steps of setting at least one threshold; at a Network Control Center (NCC) adjusting allocated resources based on the Constant Resources Allocation (CRA) after detecting whether Satellite Access Control is lost or not; compensating transmission delay by reallocating if the mobile terminal returns from the NLOS region within a first threshold duration, wherein the mobile terminal maintains the fine sync state during the first threshold duration; and deallocating all resources allocated based on the CRA if the mobile terminal does not return from the NLOS region within the first threshold duration.
