Title: Gate turn off thyristor
Inventor: YAO TSUTOMU
IPC: H01L29/74
Filed: 1983-05-25
Abstract: PURPOSE:To give the power of stopping reverse directional voltage by possessing the second control electrode by putting an anode side p type emitter junction in an electrostatic shielding type structure. CONSTITUTION:When a control signal whereby a control terminal G1 turns at a positive potential is given between the control terminal G1 and external terminal K in the state of forward directional stopping by impressing the voltage whereby an external terminal A turns at a positive potential between the external terminals A and K, the titled device turns on. When the second control signal whereby a control terminal G2 turns at a positive potential is thrown in between said terminals G2 and A in synchronization with the throw-in of a control signal at a negative potential with respect to said terminal K between said terminals G1 and K, internal carriers in the neighborhood of a pB type layer drawn out to said terminal G1 and those in the neighborhood of an nB type layer to said terminal G2, respectively. After shielding action completes, it follows that a reverse bias is impressed on the junction between both the pE and nB type layers by means of a control signal voltage. Accordingly, depletion layers connect and expand to the main surfaces 2 and 3 in parallel, because the p-n junction of said layers is in proximity. Therefore, after the current is shielded, the power of stopping reverse voltage can be kept even when the polarity of the voltage is inverted.

Abstract: PURPOSE: To prevent the lower layer aluminum film wiring of a semiconductor device from excessively corroding by providing selectivity at the lower layer aluminum film when aluminum  oxide film for insulating the lower layer aluminum film wiring is removed by gas plasma treatment.  
     CONSTITUTION: An insulator layer 3 having an opening 4 is coated on a semiconductor substrate 1 incorporating an element region 2 at the position corresponding to the opening 4. An  aluminum film 5 is coated on the entire surface of the insulator layer 3, and a hybrid aluminum  oxide film 6 is further coated on the film 5. Then, a lower layer wiring photoresist film 7a is  coated on the desired surface area of the film 6, and the regions coated with no film 7a are converted into porous aluminum oxide films 8. Then, the film 7a is removed from the surface of the  film 6, and silicon oxide film 9 is, for example, coated instead as inter-layer insulator film. Further, a photoresist film 7b having an opening pattern is coated on the surface of the film 9 to  thereby chemically etch the film 9 so as to expose the film 6. Then, the film 6 is corroded to be  removed through the opening by means of plasma treatment to thereby expose the surface of the  lower layer aluminum film 5. Since the hybrid aluminum oxide film 6 is corroded several times  faster than the films 5 and 9 at this time, it does not excessively corrode. Then, a metal film 11  is wired in contact with the film 5. Thus, the through hole opening treatment can be completed  by only one photoresist film coating treatment.
