Abstract: PURPOSE:To make a channel length short, to be excellent in a breakdown-strength characteristic and a high-speed property and to realize a high integration by a method wherein a source region, a drain region, a first gate electrode and a second gate electrode in respectively specific shapes are formed on the surface of a semiconductor substrate. CONSTITUTION:A source region and a drain region are formed on the surface of a semiconductor substrate 1 so as to sandwich a channel region. Second gate electrodes 6 which are insulated from the source region, the drain region and a first gate electrode 3 are formed on-the side faces of the first gate electrode 3 which is insulated from the channel region. As a result, a potential at the end parts of the source region and the drain region is influenced by a potential of the second gate electrodes 6 due to a capacitive coupling action. On the other hand, the potential of the second gate electrodes 6 is influenced by a potential of the first gate electrode 3 due to a capacitive coupling action. Consequently, a potential in regions at the end parts on the channel side of the source region and the drain region is changed according to the potential of the first gate electrode 3. Thereby, it is possible to enhance the breakdown-strength characteristic of a transistor and to realize a high-speed operation.

Title: Detecting method for magneto-resistance magnetic head
Inventor: NAGATA YUJI
IPC: G11B5/02
Filed: 1985-08-02
Abstract: PURPOSE:To improve remarkably 2nd order distortion by providing at least three electrodes to one MRE, dividing equally a magnetic field detection section of the MRE, flowing a sense current into the inside of the MRE divided into two in opposite direction to each other and applying differential amplification to the outputs obtained. CONSTITUTION:No bias conductor to apply a bias magnetic field to the MRE 11 is provided, three electrodes are used to flow the sense current to the MRE 11 and the MRE 11 is divided equally by the three electrodes. In operating a YMRH 10, constant current power supplies 14a, 14b to flow the sense current to the MRE 11 are connected at first to use a center electrode 12b as a common electrode. The direction of the sense current flowing to the 1st detection section 13a and the 2nd detection section 13b of the MRE 11 is opposite to each other to apply self-bias in the opposite direction. Thus, in flowing a signal magnetic field to the MRE 11, the 1st detection section 13a and the 2nd detection section 13b generate a voltage change in opposite phase to each other. Thus, the 2nd order distortion is improved remarkably and noise due to sliding is eliminated.
