Filed: 1988-03-22
Abstract: PURPOSE:To facilitate a clear marking with a simple means by a method wherein the marking is applied to the flat surface of a compound semiconductor wafer with the oxide of the compound and the oxide of the element of the compound. CONSTITUTION:In order to apply a marking to a GaAs wafer, after the rear of the wafer is lapped and subjected to chemical etching, an engraved metallic stamp is heated to about 300 deg.C and lightly pressed against the rear of the wafer in the air to form a black oxide film. The film is made of the oxide of GaAs and the oxide of As and has excellent etching-resistant properties and is clear and stable. Therefore, the excellent marking can be obtained and the control of the wafers can be performed securely.

Abstract: PURPOSE:To quickly write the status of line as a digital monitor signal, by providing the high-order address latch circuit to write the digital monitoring signal in a transmission storage memory, low-order address generating circuit and a 16-bit latch circuit. CONSTITUTION:A processor 14 sets the status of lines, the 1st instruction outputs the high-order address of a transmission storage memory 11 and the 2nd instruction outputs the digital monitor signal (SS signal bit) for 16 lines' share, in the number of bits possible for simultaneous output, e.g., in 16 bits, by the control bus. Next, the low-order, address of the memory 11 is produced from a 16-notation counter 22  to constitute the write-in address together with the high-order address stored in a  circuit 21, and an SS signal bit corresponding to this address is written in the memory 11 through a 1/16 selector 24 from a data latch circuit 23 sequentially in 16 bits. Thus, since no instruction from the processor every write-in of 1 bit is required, the write-in can quickly be completed.
