Title: Negative feedback amplifier circuit for high frequency semiconductor integrated circuit
Inventor: TANBA NORIYUKI
IPC: H03F3/19
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a gain stabilized against a temperature change by providing a 1st resistor and a capacitor as the negative feedback circuit of an amplifier and forming serial 2nd resistors respectively through the same semiconductor process on the signal line of an amplifier circuit. SOLUTION: Since the resistors formed by using the same process layer as a resistor to be used for the feedback circuit are serially inserting (R2) to the signal line, when a resistance value is increased by process fluctuation, feedback quantity is decreased and the circuit gain is increased. When the resistance values serially inserted to the signal line are increased, on the other hand, a circuit loss is increased and the circuit gain is operated to be decreased. When the resistance value is decreased by the process fluctuation, on the contrary, the feedback quantity is increased and the circuit gain is operated to be decreased. However, the resistance values serial to the signal line are decreased, the circuit loss is a little and the circuit gain is operated to be increased.  Even when the resistance value on a semiconductor substrate is fluctuated, the circuit gain can be kept constant. Even against the temperature change, the gain can be stabilized because of the resistance formed through the same process.

Substrate 3 is then etched to form the lamination of semiconductor layer 2 and insulator film 1 in a fixed shape and covering over electrode 4 and 5, and then the lamination of layer 9 and 8 is obtained at the crossing part of the connecting electrode. Then the resist is removed with the second electrode layer of Al, and gate electrode 6 plus connecting electrode 7 -3  and 7 -4  are formed by the photo etching. Thus the manufacture complates. In this way, the high-accuracy mask matching can be omitted just by masking the edge of the substrate.

Abstract: PURPOSE: To curtail the manufacturing time of an electroforming mold by depositing a lead-tin alloy to a matrix applied with nickel plating, carrying out back metal casting using an alloy having a good adherence to the above described alloy as a back metal material and mold releasing of the matrix after cooling.  
     CONSTITUTION: Nickel electroplating or nickel non-electroplating is applied on the surface of the matrix 1, and then the matrix 1 is dipped in an alloy having a ratio of lead to tin of 40/60W60/40 and molten and heated, and the lead-tin alloy is deposited on the nickel plated matrix at a thickness of 40W200 microns. The matrix 1 is arranged within a casting metal frame 2 and fixed by means of a nut 3. Back metal casting is carred out within the metal frame 2 using an alloy of the lead-to- tin ratio of 90/10, and the alloy is heated by means of a heater 5. While maintaining the alloy in a semi-molten state at 280°C, pressure is applied onto the alloy for 30min from the upward by a processing tool 6, and after coagulation, it is cooled off to the normal temperature, and thereafter the matrix is released. In the above described method, it is sufficient to apply a thin nickel plating, and accordingly the plating time may be short.

Delay circuits 11 and 12 and subtractors 17 to 19 constitute an HPF and are operated by the CK2 to process the output OS, and data interpolating circuits 15 and 16 convert delay data to data synchronized with the CK1 again. Thus, the memory capacity of circuits 11 and 12 is reduced to miniaturize a device.
