Abstract:
The development is described of fabrication techniques for construction of a silicon Hall ef fect element with characteristics suitable for application in an analog multiplier. The rel ative merits of various semiconductor materials are considered, and the reasons for the selection of silicon are outlined. The considerations necessary for the design of the element package structure are developed, and the tests required to characterize the Hall element in terms of electronic design parameters are also developed. Approximately 24 successful silicon elements were processed, and three pairs were mounted in suitable magnetic structures so as to obtain complete element packages. Experimental tran sistorized circuitry was constructed for use with these element packages in order to exhibit the ability of the silicon Hall device to multiply.
