Method for forming a fine pattern by using a patterned resist layer
 A fine pattern formation using an electron beam induced resist, and use of the resist in making semiconductor devices are disclosed. Collimated electron beam is irradiated and scanned along a desired pattern on a layer on which a resist layer of a desired pattern is deposited under an atmosphere containing a starting material layer for the resist. The resist thus deposited is partially removed by reactive ion etching to remove the skirt like portion of the resist layer, or totally removed by reactive ion etching during or after processing by using the resist layer as a processing mask. Since the resist layer width is determined by a diameter of the collimated electron beam, line width of less than hundred .ANG. can be directly drawn. There are also disclosed processes using the resist layer in manufacturing semiconductor devices.
