Abstract:
A method of producing a glass/metal package where a glass portion of the package is built up around a provided leadframe (10) using applications of solderable and glass pastes (20) which are subsequently fired (30). The glass paste and leadframe are chosen to have similar coefficients of expansion and the leadframe is pretreated to degasify and control oxidation of the metal to promote glass adhesion to the leadframe and prevent microcracking at a glass/metal interface. A seal ring is applied to the glass paste (40) and a lid is attached to the seal ring (50). The package is used to provide a sealed inert internal environment for sensitive electronic components such as a piezoelectric element. The package may be configured for leaded or surface mounting (60).
Abstract:
A method for fabricating a field emission display (100) includes the steps of providing a cathode plate (102), providing an anode plate (104), providing a spacer substrate (160) made from a bulk spacer material (109), cutting the spacer substrate (160) to define a spacer (108) having a surface (107), passivating the surface (107) of the spacer (108) using the bulk spacer material (109) to form a passivation layer, and disposing the spacer (108) between the cathode plate (102) and the anode plate (104). A field emission display (100) which includes a cathode plate (102) having a plurality of electron emitters (124), an anode plate (104) opposing the cathode plate (102), and a spacer (108) extending between the cathode plate (102) and anode plate (104). The spacer (108) has a passivation layer made from bulk spacer material (109).
Abstract:
A field emission display (100) includes a cathode plate (102) having a plurality of electron emitters (124), an anode plate (104) opposing the cathode plate (102), and a bulk-resistive spacer (108) extending between the anode plate (104) and the cathode plate (102). The bulk-resistive spacer (108) is made from an electrically conductive material. The resistivity of the electrically conductive material is selected to remove impinging charges while preventing excessive power loss due to electrical current through the bulk-resistive spacer (108) from the anode plate (104) to the cathode plate (102).
