Abstract: A method for fabricating a compound semiconductor device is provided to avoid a loss of the effective length of a gate electrode by performing a gate recess process in two steps. An etch stop layer(213) and an ohmic layer are formed on a schottky layer. A nitride layer(217) is formed on the ohmic layer. The nitride layer is patterned to form a fine gate pattern. The ohmic layer is selectively etched to form a first gate recess by using the fine gate pattern wherein the ohmic layer can form a recess profile of an undercut shape by a wet etch process. An oxide layer is deposited on the nitride layer to form an oxide layer spacer. The etch stop layer is etched to form a second gate recess. A gate metal is formed on the nitride layer. A first photoresist pattern is formed on the gate metal, and a first metal layer is formed on the first photoresist pattern. The first photoresist pattern is removed by a lift-off process to form a head portion of an asymmetrical gate electrode made wherein the head portion is made of the first metal layer. The gate metal is patterned by using the head portion of the asymmetrical gate electrode as a mask.

Abstract: An apparatus and a method for creating billing information for IP-based services are provided to increase reliability for IP-based services by creating billing information containing CDRs(Call Detail Records) and TDRs(Traffic Detail Records) so as to calculate service charges in consideration of transmission quality. An apparatus(100) for creating billing information for IP-based services comprises a CDR creation part(110), a TDR creation part(120), and a billing information processing part(130). Based on a QoS-guaranteed service session to provide an IP-based service to a user, the CDR creation part creates a CDR containing at least one among user information, the start time of the service, the end time of the service, the time used for the service. The TDR creation part collects flow information transmitted through the QoS-guaranteed service session and creates a TDR for the service. The billing information processing part combines the created CDR with the created TDR and creates billing information for service charge calculation.
