A process for forming CMOS devices is disclosed in which disposable spacers are used to obtain a structure having improved gap-fill characteristics. First, gate film stacks are formed on the substrate. A shallow implant process is performed so as to form shallow source/drain implant regions. A layer of oxide and a layer of silicon nitride are deposited and etched to form a first set of spacers that extend on opposite sides of the gate film stacks. A second implant is performed so as to form intermediate source/drain implant regions. A set of disposable spacers are then formed that extend on opposite sides of each of the gate film stacks. A third implant process is performed so as to form deep source/drain implant regions. The disposable spacers are then removed, providing more space for the subsequently-formed contact to land.

Disclosed is a method that preferably performs transmission processing to a time sequence signal of a known pattern as the pre-amble and an OFDM transmitted signal. In data communications, the general practice defines the pre-amble and detects the peaks of the mutual correlation to thereby detect synchronization. The pre-amble here is defined by the binary value in most cases for simplification of a correlation detecting device. In this case, the spectrum becomes irregular with sharp peaks and dips, which deteriorates the correlation characteristic. The method of the invention forcibly adjusts the spectrum amplitude of the pre-amble pattern on the transmitting side while retaining the phase information thereof, and thereby the method improves the spectrum and correlation characteristics while securing simplification of a correlation detecting device on the receiving side.
