Oerlikon Adds B-Stage Epoxy to Its Cover Glass Portfolio.BALZERS, Liechtenstein -- Oerlikon Optics is a leading supplier of cover glasses to the semiconductor packaging industry and is well known for the outstanding cleanliness of its coatings. By adding b-stage epoxy epoxy Any of a class of thermosetting polymers, polyethers built up from monomers with an ether group that takes the form of a three-membered epoxide ring. The familiar two-part epoxy adhesives consist of a resin with epoxide rings at the ends of its molecules and a curing to the portfolio these cover glasses are made suitable to a broader variety of applications. The packaging of light sensitive semiconductor devices consists of a cover glass mounted to a ceramic backplane An interconnecting device that has sockets for printed circuit boards to plug into. Passive and Active Although resistors may be used, a "passive" backplane adds no processing in the circuit. . One of the technologies applied for the assembly of these two pieces is a so called b-stage epoxy. This epoxy is supplied on the glass lid in a dry and particle-free state and the curing of the epoxy at the eventual packaging it is done by tempering - depending on the epoxy at 120[deg]C to 150[deg]C. Oerlikon has added b-stage epoxy printing and processing to its cover glass lids portfolio. Together with clean glass and low defect coatings this allows for a comprehensive supply to semiconductor packaging and prevents customers from chemical handling. As this type of epoxy is available in black color - better absorbing than any black Chrome - it may additionally be applied as an aperture protecting underlying electronics against light. Oerlikon has carefully selected the latest developed epoxies that improve and ease the assembly processing. The focus of the selection has been on lowering the curing temperature and providing an excellent hermetic seal For other uses of "hermetic", see hermetic (disambiguation). A hermetic seal is an airtight seal. For example, tin cans are hermetically sealed. The term is often used to describe electronic parts that are designed and intended to secure against the entry of microorganisms . The epoxy is applied and processed in a way that allows for highest cleanliness on the clear aperture of the cover glass. Besides adhesive bonding Adhesive bonding The process of using an adhesive to manufacture an assembly. The adhesive-bonded assembly is known as an adhesive joint, and the materials to which the adhesive adheres are known as the adherends. technologies Oerlikon supports soldering of cover glass to backplanes made of ceramics or metal alloys. Gelot[TM] coated glass surfaces - providing a Gold surface - can be perfectly soldered with Pd or Au pre-frames to backplanes. Soldered assemblies provide a perfect hermetical seal and are stable at high temperatures. Whereas b-stage epoxy is mainly applied for CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. packaging, soldering suits best for packaging of MEMS (MicroElectroMechanical Systems) Tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. In the research labs since the 1980s, MEMS devices began to materialize as commercial products in the mid-1990s. devices. Eventually, with the addition of b-stage epoxy to its services Oerlikon intends to make its outstanding low defect coatings applicable to a broader range of semiconductor packaging solutions.
