Title: Negative resist composition
Inventor: SHIOBARA HIDESHI
IPC: H01L21/027
Filed: 1994-03-25
Abstract: PURPOSE:To obtain a chemical amplification type resist having high resolution and high sensitivity by adding a material that generates a basic substance with the exposure for forming a pattern in the resist pattern forming process and another material that generates an acid in the post-exposure heating process to a resist composition. CONSTITUTION:This resist consisting of a base resin and a dissolution inhibitor also contains a compound that is decomposed with acid or heat to form an acid (heat-acid generating agent) and another compound that generates a basic substance with radiation-exposure (photo-base generating agent). At the time of selectively subjecting the resist film 2 to the exposure 1, the basic substance 4 is generated in the exposed part 3 of the resist in this process. In the subsequent heating process, since only the acid 6 is present in the unexposed part 2 of the resist, the decomposition of the dissolution inhibitor occurs there. On the other hand, since both the acid 6 and the basic substance 4 are present in the exposed part 3, the neutralization reaction of them with each other occurs and accordingly, no decomposition of the dissolution inhibitor occurs there. Thereafter, the resist is developed to obtain the negative resist pattern 7.

Title: Positioning apparatus of probe and scanning-type tunnel microscope
Inventor: SAKAI AKIRA
IPC: H01J37/28
Filed: 1990-03-08
Abstract: PURPOSE:To easily position a probe by detecting the change of a current when a charged particle beam emitted from an end of the probe passes an edge of a sample. CONSTITUTION:A probe 1 is aligned with the position of an edge of a sample 2 by an optical microscope 10, and brought close to the edge of the sample 2 by a manual access mechanism 11. At this time, the probe 1 is set slightly closer to the sample than the edge. As a current is monitored by a minute ammeter 9 when a negative voltage is impressed to the probe 1 from a high voltage source 6, the probe 1 is gradually brought near to the cross section of the sample 2 by an actuator 3 for rough adjustment. Consequently, a field emission current starts to flow from the probe 1 to the sample 2. At this time, if the probe 1 is fixed and the sample 2 is moved by a piezoelectric actuator 12, the cross section of the sample 2 comes outside the electron beams and no current is detected. Therefore, if the sample 2 is moved so that the value of the current becomes a middle point of the current change, it is possible to align the probe 1 with the edge of the sample 2.

The warning list is sent from a warning list transmission means 4. Thus, the original to be distributed while awaiting the access from the destination is more quickly and surely distributed.
