Filed: 1988-01-27
Abstract: PURPOSE:To form a wafer of a first layer having no chip rotation, and to improve an alignment accuracy of other layers by measuring a mechanically- remaining reticle setting error in the rotation direction, and feeding back an error amount to the position control of an XY stage. CONSTITUTION:A reticle 1 is first set, and the displacement of a reticle alignment mark 16 thereon from a reticle setting mark 17 is measured. Then, whether the measured displacement falls within a predetermined allowable value or not is determined. If it falls below the allowable value, a remaining setting error is stored in a memory. Thereafter, an correction amount by which a wafer 3 must be driven in a direction Y at the time of stepwise movement is calculated, and it is decided whether or not it must be stepwisely moved in a direction X. The movement is executed while driving for correction in the direction Y is executed. Subsequently, an exposure is achieved, whether the exposure is completed for all shooting or not is decided, and if it is not yet completed, the process is again repeated.

Title: Bubble memory controller
Inventor: KANEKO KEIICHI
IPC: G11C11/14
Filed: 1989-01-24
Abstract: PURPOSE:To prevent the destruction of data by providing an inhibiting means which inhibits the switch of the selection signal in case a rotary magnetic field is applied to a bubble memory block selected by the selection signal via a control signal. CONSTITUTION:The addresses of memory blocks 4a - 4n are designated by a register 3, and a selection signal is outputted. At the same time, an action signal is inputted to an inhibition circuit 10 while a rotary magnetic field is controlled by a control circuit 7. The circuit 10 inhibits the input a register write clock to the register 3. Therefore the register write clock is never outputted to the register 3 from the circuit 10 even in case an MPU 1 has the runaway and a write pulse is outputted to the circuit 10 by mistake. As a result, the selection signal is never switched inadvertently and the normal control is continued to the rotary magnetic field. Then the destruction of data can be prevented.
