摘要： An optical transceiver includes an optical transmitter. The optical transmitter varies the wavelength of its output beam in accordance with the setting of a digital to analog converter. Two split beams emerging respectively from beam splitters are introduced into a photodetector and a wavelength filter, respectively. A quotient is calculated by dividing the digital value output from an analog to digital converter (ADC) by the digital value output from another ADC. A memory address m is then determined based on this quotient without making any calculation for compensating for the imperfect characteristics of the wavelength filter. A wavelength notification value is then selected from a wavelength notification table based on the determined memory address m, and sent to the system host.

摘要： A control circuit for an optical transmitter/receiver that transmits/receives an optical signal, comprises: a memory having a digital value storage area and an area that stores limit values; a register; an analog/digital conversion circuit that receives analog signals indicating operating parameters of the optical transmitter/receiver, converts the analog signals to respective digital values, and stores the digital values in the memory; a comparison logical circuit that compares the digital values with the limit values, generates flag values, and stores the flag values in the register; and an outside interface that allows an outside host apparatus to access the memory and the register to read the flag values and monitor an operating condition of the optical transmitter/receiver from outside.

摘要： There is described formation of a contact hole without involvement of damage to an etching stopper film and deterioration of electric characteristics, achieved by means of a self-alignment method. An interlayer oxide film is etched through an opening of a resist mask, and by means of plasma etching through use of a processing gas comprising a mixture of a rare gas and a CF-based gas, thereby tapering a shoulder of the silicon nitride film. Alternatively, a silicon oxide film and a silicon nitride film are continually etched through an opening of the resist mask, by means of plasma etching through use of a CH2F2 gas added to a mixed gas including a rare gas and a C4F8 gas.

摘要： Provided are a method for manufacturing contact structure to prevent, in the wire of a borderless structure, erosion in the contact area between the wire and a conductor. An interlayer insulating film (300) having a wire burying hole is formed and a conductor (400) is buried in the hole. Then, a wire layer (500) covering the hole is formed on the interlayer insulating film (300). The wire layer (500) is made so as to have a borderless structure by using a resist (540) as a mask. A barrier metal layer (510) suppresses erosion in the contact area between the conductor (400) and the wire layer (500).
