Title: Automatic impedance measuring device - uses bridge voltages to control oscillator frequency
IPC: G01R27/16
Filed: 1973-10-04
Abstract: The frequency of operation is adjustable and phase measurements are made in order to reduce measurement errors. In a bridge circuit (Z1, Z2, Z3, Z4) one arm comprises two resistive components (Z1, Z2) and the other arm comprises a resistive component (Z3) and the unknown impedance (Z4).

As described 200 ohm cm. P-type silicon wafers are cleared as by etching followed by washing in aqueous and organic solvents and introduced into a sputtering apparatus the details of which are described with reference to Figs. 3 and 4 (not shown). Then with the wafers heated to above 400‹ C. adsorbed impurities are removed by bombardment with an argon ion beam first from the targets and then from the wafers to provide a dislocation free surface. The wafers are then raised to 900‹ C. and an N + layer 1000-1500 Š thick deposited thereon by directing the beam on an arsenic or antimony-doped silicon target. With the wafers at room temperature the beam is directed successively on molybdenum and nickel targets to form layers of molybdenum and nickel respectively 1000 A and 2 Á thick and optionally an intermediate layer of graded composition. After inverting the wafers automatically, or after breaking the vacuum, manually a P + layer of boron-doped silicon and contact layers of molybdenum and nickel are deposited similarly on their back faces.
