Filed: 1983-02-18
Abstract: PURPOSE:To reduce the required storage capacity of a line buffer and to improve the economization of a message accumulating and reproducing device, by providing a switch which connects an input/output line and plural line buffers to each other. CONSTITUTION:Message blocks coming from an input/output line 1 are selected by a processor 5 and are accumulated in an optional empty line buffer 2' connected by a changeover switch 6.

Title: Microscopic pattern forming method
Inventor: WATABE HEIJI
IPC: H01L21/302
Filed: 1992-01-17
Abstract: PURPOSE:To conduct a direct patterning by electron beam etching using no mask layer in a highly precise manner by conducting a microscopic pattern lithography while the material to be processed is being cooled. CONSTITUTION:The reaction of a microscopic region is accelerated by the irradiation of a focussed electron beam on the surface of the material to be processed 103 on which a reaction gas adsorption layer 102 is formed. At this time, the gas etching of sample surface and processing side wall, generating while etching is in progress, can be suppressed by cooling the material to be processed. To be more precise, the chemical reaction between a reaction gas molecule and the surface atoms of the material to be processed is accelerated, and at the same time, the reaction product 104 is efficiently removed by the effect of desorption of electron beam excitation, and the etching only by beam excitation can be made possible by completely preventing gas etching due to low temperature on the part where an electron beam is not projected. Accordingly, a microscopic pattern can directly be drawn in a highly precise manner.
