Abstract
1,018,903. Semi-conductor devices. SIEMENS-SCHUCKERTWERKE A.G. Nov. 26, 1962 [Nov. 25, 1961], No. 44706/62. Heading H1K. A recess is mechanically cut in a semiconductor body to extend through a layer of one conductivity type extending over the entire surface of a body of different conductivity or conductivity type, and then etched. At least 80% by volume of the material to be removed is removed in the mechanical cutting, the etching preferably removing only material damaged in this process. To this end where the body is silicon a specified mixture of nitric and hydrofluoric acids with a modifier chosen from acetic acid and sodium and potassium hydroxides is used. In the embodiment, Fig. 4 (not shown), a PNPN controlled rectifier is formed by cutting an annular recess through an aluminium diffused N-type layer on a high resistivity P- type silicon body using a hollow emery- or diamond-faced cylinder, followed by etching. A circular PN junction and surrounding annular control contact are formed in the circular N layer thus isolated by alloying in gold-boron and gold-antimony foils respectively. Alternatively the alloying may be effected before the recess is formed.
