  • Patent number: 6303860
    Abstract: An encapsulated device containing a bladder disposed between a wall of the case and the encapsulant. The bladder defines a space devoid of encapsulant, thereby allowing the unimpeded thermal expansion of the encapsulant. By reducing thermal expansion stresses on the encapsulated devices, the reliability of the encapsulated device is improved. The device is formed by installing a component within a case; positioning a bladder within the case; depositing encapsulant with the bladder in an inflated condition; and deflating the bladder.

  • Patent number: 4845366
    Abstract: The present invention involves apparatus and methods for introducing ion source material into an ion implant system for use in connection with Freeman type sources. A vaporizer unit which is removable from the system is prepared for insertion into the ion implant equipment outside the system. It is cleaned, a new vial of ion source material is introduced and it may be pre-heated to degas it or to prepare it for use in the system. The vaporizer unit which is currently in use is removed, to be cleaned and recharged, and the previously prepared vaporizer unit is inserted, sealed in place and the vacuum established. The ion implant system is, then, ready to resume operation with minimal down time. The vaporizer unit comprises a vaporizer block of high heat conductive material such as copper which includes three cavities or wells. One cavity contains a heater, one a gas flow path for heating and/or cooling, and one contains a sealed vial of semiconductor dopant.
