Title: Dual processing system
Inventor: KUBO NORIO
IPC: G06F15/177
Filed: 1985-04-19
Abstract: PURPOSE:To improve a crosscall function performance by performing execution processings in parallel in case of commands which are not accompanied with data transfer when a device is cross-called from respective processors in parallel. CONSTITUTION:A disc controller 2 has the crosscall control function to perform data transfer or the like between plural processors 1a and 1b. The first means 24 which divides command from processors 1a and 1b into the first group of commands accompanied with data transfer and the second group of command which are not accompanied with data transfer is provided in a processing circuit 23 of the controller 2. If a command belonging to the first group is issued from the processor 1a, the circuit 23 executes the processing. If a command belonging to the first group is issued from the processor 1b in this state, the second means 25 keeps this command waiting and executes the processing of this command from the processor 1b after the processing of the preceding command from the processor 1a is terminated. If a command belonging to the second group is issued from the processor 1b the third means 26 performs processings in parallel. Thus, the crosscall function is improved.

Abstract: PURPOSE:To form the photoresist compsn. which is made soluble in a developer by the effect of an acid and has the patterning characteristic not affected by moisture environment at the time of patterning by incorporating a polymer deriv. the hydroxyl group of which is protected by an acetal group eliminated by the acid and an acid generating agent which generates the acid when irradiated with light into the above compsn. CONSTITUTION:The resin which is one of the constituting components of the compsn. is the polymer deriv. the hydroxyl group of which is protected by the acetal group eliminated by the acid. More specifically, the resin is constituted of the polymer deriv. the hydroxyl group of which is protected by the acetal protective group of the structure having at least one piece of hydrogen on the adjacent carbon atoms of the acetal carbon and, therefore, the elimination of the protective group is executed by the effect of the acid without the aid of moisture. The photoresist compsn. which is hardly affected by the atmosphere of the lithography stage is thereby obtd. The relieving of the requirement for the atmosphere control of the resist processing stage is consequently expected and the decrease in the fluctuation of the quality of the sample coated with the resist with lapse of time is expected.
