IMEC developed a new "flexible" package for ICs
Recently, IMEC collaborated with Intec Laboratories of Ghent University to develop a thin and flexible package for ICs.
The two organizations called this cooperation project "Shift". Shift began on January 1, 2004 and is expected to be completed on December 31, 2008. Shift's total investment will be $14 million, of which $7.2 million will be funded by EU and Swiss authorities.
According to IMEC, the new package has a thickness of only 50 microns and is flexible enough to be used in high-end, multi-functional electronic systems. Chips using this type of packaging can be contained in soft boards, small pieces of textiles, and relatively soft displays.
This package has been shown through silicon wafers with a thickness of 20-30 microns. This package consists of two layers: a polyimide layer and a metal layer with a total thickness of 50 microns. The thickness of the polyimide layer is 20 microns and it is wrapped in a hard glass. The silicon wafer and the polyimide are bound with cyclobutane - the function is to fix the silicon wafer. The cyclobutane is pre-cured, so it can maintain its properties at high temperatures. Since the cyclobutane between the silicon wafer and the polyimide has no air between them, no further vacuum processing is required. After the silicon wafer was coated with polyimide, it was covered with a hard film with a thickness of 20 μm. IMEC said that the role of the hard film is through the dura mater, and the laser electromagnetic wave can come into contact with the opening of the silicon wafer. The second layer of the package consists of a titanium-tungsten-copper alloy, which has a smooth, hard surface that effectively protects the silicon wafer from damage.

Outdoor furniture refers to furniture used for outdoor environment, mainly used for outdoor leisure, entertainment and dining activities. The classification of outdoor furniture can be divided according to the material, function and shape.
First, classification by material
1. Wooden outdoor furniture: Wooden outdoor furniture is usually made of natural wood, such as teak. Wooden furniture has a natural, rustic character and is suitable for outdoor Spaces such as gardens, terraces and courtyards.
2. Metal outdoor furniture: Metal outdoor furniture is usually made of iron, aluminum, stainless steel and other metal materials. Metal furniture has the characteristics of durability and stability, suitable for long-term use in outdoor environment.
3. Cloth outdoor furniture: Cloth outdoor furniture is usually made of waterproof, sun protection and other special treatment of fabric. Fabric furniture with soft, comfortable characteristics, suitable for use in outdoor leisure areas.
Second, Classification by function
1. Leisure Chair: Leisure chair is the most common kind of outdoor furniture, usually used for outdoor leisure, sunbathing and other activities. There are a variety of leisure chairs, folding chairs, recliners, rocking chairs and so on.
2. Dining Table And Chair: Dining table and chair are mainly used for outdoor dining, usually consisting of a table and several chairs. Dining tables and chairs of various styles, there are round tables, square tables, etc., suitable for different venues and the number of people dining needs.
3. Parasol: Parasol is used for outdoor shading, which can effectively block direct sunlight and provide a cool resting environment. There are various styles of sunshade umbrellas, including ordinary umbrellas, large umbrellas, and rotating umbrellas.
Third, Classification by shape
1. Chairs: including ordinary chairs, rocking chairs, recliners, etc., suitable for outdoor leisure and sun.
2. Table category: including dining table, coffee table, side table, etc., suitable for outdoor dining and placing items.
3. Sofa category: including single sofa, double sofa, combination sofa, etc., suitable for outdoor leisure and parties.
4. Reclining chairs: including hammocks, reclining chairs, etc., suitable for outdoor naps and rest.
5. Queue class: including benches, benches, etc., suitable for outdoor queuing and waiting.
In summary, the classification of outdoor furniture can be divided according to material, function and shape. Different outdoor furniture is suitable for different outdoor environment and activity needs, choose suitable outdoor furniture can provide comfortable and convenient outdoor life experience.
