Title: Selective nucleation
Inventor: NIIZAWA TSUTOMU
IPC: H01L21/285
Filed: 1988-12-06
Abstract: PURPOSE:To facilitate nucleation selectively and facilitate filling minute contact holes and the like by a method wherein a pulse-type light having a wavelength at which the light is transmitted through mask material and absorbed by the surface of a substrate is applied over the whole surface of the substrate in the initial stage of deposition. CONSTITUTION:On a silicon substrate 1, source and drain regions 2 are formed by implantation of ions of impurity having a conductivity type opposite to that of the substrate 1 and a gate electrode 3 is formed with a gate oxide film between. After a silicon oxide film is formed over the whole surface, contact holes 5 are formed. Then a light 6 having a wavelength at which the light is transmitted through the silicon oxide film 4 and absorbed by the surface of the silicon substrate 1 is applied over the whole surface of the substrate in a triisobutyl aluminum atmosphere. Therefore, by local and transient heating, only raw gas brought into contact with particular parts is decomposed by heat. With this constitution, sufficient nucleation can take place at those parts only and, as CVD can be applied to nucleation regions relatively easily after the nucleation, the contact holes can be filled easily.

Title: Call collision avoiding method for lan
Inventor: UEDA HIROYUKI
IPC: H04L12/40
Filed: 1988-12-09
Abstract: PURPOSE:To change the sequence of occurrence of calls and to avoid the collision of the call by using an ID (characteristic Variable) and setting the initial value and the skip interval of generation of a random number to each node. CONSTITUTION:When the collision of calls is detected, whether or not it takes place at first is checked. In the case of the first collision, a random number corresponding to the ID of a node is giving as an initial value from a random series in common to each node (step ST33). In the case of not being the first collision, a random number skipped by a skip interval corresponding to the ID of the node from the random value decided precedingly is given (step ST32). The random number decided as above is used as the recall waiting time of a node whose collision of calls is detected (step ST34). Since the initial value and the skip interval differ from every ID of each node, the collision is avoided.
