Patent JP-H01171273-A (JP)
Title: Bidirectional semiconductor switching element
Inventor: TAGAMI SABURO
IPC: H01L29/861
Filed: 1987-12-25
Abstract: PURPOSE:To set a holding current to an arbitrary value by dividing second and fourth layers in contact with a common electrode into a plurality of regions which penetrate first and fifth layers, and dividing second and fourth layers in contact with the common electrode of a switching element having five adjacent layers of alternately different conductivity types into a plurality of regions which penetrate first and fifth layers. CONSTITUTION:A plurality of regions of first and second base layers 2, 3 are respectively brought into contact with electrodes 61, 61 in short holes which penetrates first and second emitter layers 4, 5. Since an electron current 18 is divided to both sides right under the P-type emitter layer 4 to arrive at the contact region 9, a potential drop of resistance rho/1 of the half of the whole sheet resistance rho right under the layer 4 merely occurs. Accordingly, a holding current IM can be set to a predetermined value or more without reducing the total area of the electrode 61 or 62, i.e., without reducing the capacitance.

Abstract: PURPOSE:To simplify the title device and to reduce aberration and noise by causing the aperture number in a condenser lens to be different in the moving direction of a recording medium or an optical beam, and in the direction to be orthogonal to this moving direction. CONSTITUTION:For the aperture shape of the condenser lens, the aperture number is caused to be large in the same direction as the proceeding direction of a track so as to be a spot diameter to be stopped down in order to obtain the smaller number of signals by the part of the noise. On the other hand, in the orthogonal direction of the track, the aperture number is caused to be small so as to be the spot diameter which is slightly larger than a track width. Thus, by causing the aperture shape of the condenser lens to be an elliptic shape which is slender in the proceeding direction of the track, comatic aberration or the aberration of astigmatism, etc., is reduced and further, a beam spot pattern, which has the small influence of the noise part, can be obtained.
