A method of production of a semiconductor device such as a plastic pin grid array (PPGA) and a plastic ball grid array (PBGA) having a cavity-fill form. In this method, first, a semiconductor element (3) is placed in a cavity (6) formed in a multiple step-like substrate (2). Under this state, a pellet (7), which is in a solid state at a normal temperature, made of an encapsulating resin composition containing specific components, and has specific characteristics, is placed on the semiconductor element (3). Next, the semiconductor device is heated so that the pellet can melt to fill the cavity (6) with the composition, thereby encapsulating the semiconductor device (3). According to the present invention, a semiconductor device having low stress performance and excellent moisture-proof reliability can be efficiently produced.

A film of a II-VI group compound semiconductor of at least one of elements belonging to the II group of the periodic table and at least one of elements belonging to the VI group of the periodic table is deposited on a substrate. When the film is deposited on the substrate, a plasma of nitrogen in an excited state is applied to the substrate while removing charged particles from said plasma by a charged particle removing means. The deposited film of a nitrogen-doped II-VI group compound semiconductor has an increased percentage of activated nitrogen atoms and improved crystallinity.

The multicast communication scheme which can enable a user to easily comprehend the multicast groups existing on the network, easily carry out an operation to join a desired multicast group, and easily specify a desired communication quality. At each user terminal, a virtual space with a plurality of regions defined therein in correspondence to a plurality of multicast groups is displayed on a screen, while an information indicating a range of each region in the virtual space is stored in correspondence to an address information for a corresponding multicast group. A desired position in the virtual space on the screen is specified by an input device, and joining/leaving to/from multicast groups is controlled by using the address information stored in correspondence to a region in the virtual space which contains the desired position. The display on the screen may include a plurality of zones defined within each region in correspondence to a plurality of different communication qualities, so that a communication quality of a multicast communication to be received can be controlled according to a zone within a region in the virtual space which contains the desired position.
