The disclosure relates to memory cards having an electronic component housed in a cavity. The electronic support has a first base made of silicon, with a small thickness (between 50 and 100 microns) and a thicker (between 200 and 300 microns) second base, which is deposited on the first base and is formed by a material which is harder than silicon, such as cobalt, vanadium, titanium or ceramic.

Electronic component support for memory card and product obtained thereby

In an electrostatic protection device for electronic cards, the electronic card has a module bearing, on one of its faces, a network of conducting tracks to which at least one integrated circuit is connected. Each contact is close to a contact at a reference potential. The contact bears, on its periphery, metal sharp-pointed proturberances placed so as to face other metal protuberances borne by the contacts so as to favor the formation of electric arcs between two facing protuberances.

Electrostatic protection device for electronic cards

A micromodule or chip carrier package for chip containing components has an insulating support base for carrying a series of flush-mounted contact areas. A semiconductor circuit or chip is placed on one of the contact areas and the chip is connected to the other contact areas by means of wires. A hollow case is mounted over the assembly and has a bore for receiving a drop of resin which has the function of protecting the semiconductor circuit or chip.

Method of fabrication of a chip carrier package, a flush-contact chip

An electronic card which can be reused a large number of times incorporates a semiconductor circuit provided with an area which is erasable by means of electromagnetic radiation within the ultraviolet range of wavelengths. The externally-emitted ultraviolet radiation applied to the semiconductor circuit via a card recess passes through a quartz window and impinges on the erasable area.
