Title: Manufacture of semiconductor device
Inventor: MEGURO SATOSHI
IPC: H01L29/78
Filed: 1983-08-08
Abstract: PURPOSE:To enable to easily form a well layer having a concentration distribution of reverse gradient to prevent latch-up by a method wherein an N type impurity is introduced to the entire surface of an Si substrate, and further a P type impurity is introduced at this region selectively into the substrate, thereafter the P type and N type impurities which have been introduced are thermally diffused into the substrate at the same time. CONSTITUTION:The region other than the region for forming a P type well layer is selectively covered with a photo resist film 23 in order to form the well layer, and, with the film as a mask, the P type impurity, e.g., boron to form the well layer is introduced via Si oxide film 21. In the region for forming the well layer, the layer 24 of the P type impurity, e.g., boron and the layer 22 of the N type impurity, e.g., arsenic are mixed. Next, the film 23 is removed, and the P type impurity, e.g., boron and the N type impurity, e.g., arsenic which have been introduced are thermally diffused. At this time, because the diffusion speeds of boron and arsenic into the substrate 1 are different, layers of different depths are formed on thermal diffusion treatment. Since boron has a higher diffusion speed than arsenic, it forms a deeper P type well layer.

Abstract: PURPOSE:To downsize an apparatus and reduce a cost by providing a converting means for converting an output from an amplifier to azimuth information and a non-magnetic plate with a magnet-sensitive element and an exciting coil mounted which rotates horizontally. CONSTITUTION:DC voltage is applied to an exciting coil 6 from a positive pole to a negative pole to generate a DC bias magnetic field perpendicularly to a direction of current of a first element 4 and also in a direction from lower to upper. Electric resistance of each of elements 4, 5 varies according to an incident angle of geomagnetism, and a middle point potential value taken out from an output terminal 3 also varies. That is, due to a change in the incident angle of the geomagnetism due to a rotation of a non-magnetic rotating plate 11, the middle point potential value varies with STn waves. If the plate is rotated 360 deg. with   as an origin of an azimuth sensor, a direction of   at a rotation position where the output is maximum indicates north and the direction of   at a rotation position where the output is minimum indicates south. Then by rotating the non-magnetic rotating plate 11 starting from north at a constant speed, time from start of the rotation is measured and knowing the number of rotations allow the current azimuth to be known.

Title: Method for measuring series resistance of field effect transistor
Inventor: NISHIDA MASAO
IPC: H01L29/812
Filed: 1988-06-13
Abstract: PURPOSE:To make it possible to perform highly accurate measurement wherein parasitic resistance is removed by making a minute forward current flow between one of two ohmic electrodes and a gate electrode, changing a bias from the other ohmic electrode, and applying the bias. CONSTITUTION:A source electrode 1 is grounded through an ammeter 12 and a voltmeter 11. A drain electrode 2 is connected to a voltage source VDD. A gate electrode 3 is connected to a constant current source 13. A forward current (100muA) is made to flow. The electrode 3 is grounded through a voltmeter 14. The current flowing through a source resistor Rs is the sum of the current flowing from the side of the electrode 3 and the current flowing from the side of the electrode 2. The current flowing through the voltmeter 14 can be neglected. The voltage applied on the resistor Rs is the value obtained by subtracting the read value of the voltmeter 11 from the read value of the voltmeter 14. Even if the potential at the electrode 2 is changed, the current flowing through a contact resistor R's and a gate metal resistor Rg and the applied voltage are not changed. Therefore, the resistance Rs can be obtained by dividing the changing amount of the voltage applied on the resistor Rs by the changing amount of the current flowing through the resistor Rs at this time. A drain resistance RD can be obtained in the same way.
