Definitions
- the invention relates to a component arrangement with a carrier substrate and at least one component arranged thereon.
- LTCC Low Temperature Cofire Ceramics
- PCB Low Temperature Cofire Ceramics
- One of the main advantages of the LTCC is, among other things, the low thermal expansion coefficient, which minimizes thermal stresses with silicon-based structures, in particular with components on silicon-based substrates.
- An advantage of PCB are low production costs and the exact position definition of connection pads. Disadvantages include the lack of gas tightness, a relatively high water absorption and a coefficient of thermal expansion which is not matched to silicon-based flip-chip structures.
- the flip-chip components used on PCB today are potentially not hermetically sealed, a circumstance which is particularly troublesome in filter assemblies in MEMS technology (micro-electro-mechanical system).
- a method for producing glass-based electronic components is known. There, a glass-based body is proposed which has a monolithic multilayer structure which contains at least one passive electronic component and at least one layer of glass.
- a multilayer printed circuit board with increased dimensional stability. By reducing the thermally induced expansions, the connections to the electronic components are less stressed. Furthermore, a multilayer printed circuit board for equipping with electronic components is shown, which has at least one layer whose thermal expansion behavior corresponds approximately to the thermal expansion behavior of the electronic components and at the same time substantially determines the thermal expansion behavior of the multilayer printed circuit board.
- the said layer is a glass layer or a glass-containing layer which is in intimate association with other layer materials. Thermoplastic or thermosetting materials, metals or electrically conductive or non-conductive plastics are mentioned as further layer materials.
- the invention has for its object to provide a device arrangement with a carrier substrate with component, which shows improved properties in this regard.
- the invention proposes to provide a component arrangement with a carrier substrate and at least one component arranged thereon, wherein the carrier substrate contains at least one layer of glass foil and an intermediate layer which is applied to the glass foil at least on one side and wherein the component and the carrier substrate is covered by a cover layer.
- This covering layer which covers the carrier substrate and the component, constitutes a gastight cover.
- the carrier substrate comprises a composite of glass film and at least one layer LTCC.
- the advantage of this structure results from the conformity of the expansion coefficients of LTCC and the carrier substrate with the at least one glass foil which functions as PCB. This allows a high BGA density on the LTCC substrate and makes overfilling superfluous in flip-chip bonded components.
- the component itself may be a component-carrying chip (bare die), an optionally encapsulated or already provided with a cover substrate-supported Bau ⁇ element or a module in which one or more Bauele ⁇ elements arranged on a substrate and optionally with ei ⁇ ner cover are provided.
- Multilayer substrates may include integrated passive components and interconnections.
- the component contains a multi-layered substrate and this substrate is fastened on the carrier substrate.
- the substrate may also have at least one layer of glass foil and / or LTCC.
- the component is provided to arrange the component on the glass film without any further intermediate layer.
- the expansion coefficients of the carrier substrate (about 6-7 ppm / K in LTCC) with glass film (about 7ppm / K) and the device in one direction (eg 7ppm / K along one and 14 ppm / K along the other Kris ⁇ tallachse at LiTaO 3 ) almost identical.
- Si also has a similar thermal expansion coefficient of about 4 ppm / K. With this arrangement, this is advantageously used by the expansion coefficients are matched.
- the device includes a device-structure-carrying chip.
- This component-structure-carrying chip can be, for example, a filter assembly in MEMS technology.
- a filter assembly e.g. A surface-wave filter on a piezoelectric substrate
- a mechanical Verspann rejoin turn is particularly vorteil ⁇ haft.
- the supporting chip can be arranged on the substrate or directly on the carrier substrate.
- Glass foils have almost the same thermal expansion coefficient as LTCC and are also gas-tight.
- a device arrangement according to the invention with a MEMS device (micro-electro-mechanical system), for example, a filter assembly in SAW technology (surface wave filter) hermetically protected against environmental influences.
- MEMS device micro-electro-mechanical system
- SAW technology surface wave filter
- contact elements are arranged on the underside of the carrier substrate. These contact elements are electrically conductive with connected to the device.
- the carrier substrate has through contacts, which extend from the upper side, on which the component is applied, in the direction of the lower side, and are connected to the contact element.
- the optional substrate of the device may also have plated-through holes. These plated-through holes connect the component with metallizations on the underside of the substrate and extend from the upper side to the lower side of the substrate.
- the invention proposes, in a further embodiment, to provide at least two layers of the glass foil in the carrier substrate and to provide them with plated-through holes extending through this carrier substrate or substrate.
- the plated-through holes are offset relative to each other through the respective layer of the glass sheet to the contact element.
- the invention proposes, in a further embodiment, that the covering layer contains a glob top of reaction resin.
