Definitions
- This disclosure relates to a support substrate.
- WLP Wafer Level Package
- PLP Packel Level Package
- a general method for manufacturing WLP and PLP is as follows. First, an adhesive film is affixed on a support substrate. Next, after mounting a plurality of semiconductor chips on the adhesive film, the semiconductor chips are sealed with a sealing material. Thereafter, the semiconductor chip and the sealing material are peeled off from the adhesive film. Then, after rewiring of the semiconductor chip, WLP is manufactured by dicing.
- a method of peeling the semiconductor chip and the sealing material from the adhesive film there are a method using heat, a solvent, a laser, or the like, or a method of peeling mechanically.
- the method using heat can peel the semiconductor chip and the sealant in a simple process compared to the method using a solvent or laser or the method using mechanical peeling, and the equipment investment cost Can be reduced.
- Patent Document 1 discloses the following method as a method using heat. First, a plurality of semiconductor chips are arranged on a thermosensitive adhesive as an adhesive film on the support, and on the thermosensitive adhesive. Next, the arranged semiconductor chip is sealed with plastic as a sealing material. Next, from this state, the adhesive performance of the temperature-sensitive adhesive is lost by heating to a predetermined temperature or higher, and the semiconductor chip and the sealing material are peeled from the temperature-sensitive adhesive.
- the support substrate of the present disclosure is a plate-like body made of ceramics and having a first surface and a second surface positioned opposite to the first surface.
- the first surface has an arithmetic average roughness Ra obtained from the roughness curve of 0.5 ⁇ m or less and a skewness Rsk obtained from the roughness curve is negative.
- the adhesive film is not peeled off together with the semiconductor chip and the sealing material.
- the support substrate is required to have high adhesive strength with the adhesive film.
- the support substrate of the present disclosure has high adhesive strength with the adhesive film.
- the support substrate of the present disclosure will be described in detail with reference to FIG.
- the support substrate 1 of the present disclosure is a plate-like body having a first surface 1a and a second surface 1b positioned opposite to the first surface 1a, as shown in FIG.
- an adhesive film 2 is attached to the first surface 1 a of the support substrate 1
- a plurality of semiconductor chips 3 are placed on the adhesive film 2, and the semiconductor chips 3 are sealed with a sealing material 4.
- An example that is stopped is shown.
- the support substrate 1 of the present disclosure is made of ceramics. Ceramics are excellent in corrosion resistance and heat resistance, and have higher rigidity than metals and glass. Therefore, with such a configuration, the support substrate 1 of the present disclosure can be used even when stress due to hardening shrinkage of the sealing material 4 occurs when the semiconductor chip 3 is sealed with the sealing material 4. Or it is hard to bend compared with the support substrate which consists of glass. Therefore, the position shift of the semiconductor chip 3 due to the bending of the support substrate 1 hardly occurs, and the yield is high.
- the ceramic examples include aluminum oxide ceramics, silicon nitride ceramics, aluminum nitride ceramics, silicon carbide ceramics, and cordierite ceramics.
- the support substrate 1 of the present disclosure is made of an aluminum oxide ceramic, the manufacturing cost can be reduced due to the ease of processing.
- the support substrate 1 of the present disclosure is a silicon carbide ceramic
- the silicon carbide ceramic is more rigid than other ceramics, so that it is more difficult to bend, and the semiconductor chip 3 is sealed with the sealing material 4. At this time, even if stress due to hardening shrinkage of the sealing material 4 is generated, the positional deviation of the semiconductor chip 3 due to the bending of the support substrate 1 hardly occurs, and the yield is improved.
- the aluminum oxide ceramic is a ceramic mainly composed of aluminum oxide.
- the main component of aluminum oxide refers to a case where aluminum oxide is contained in an amount of 70% by mass or more out of 100% by mass of all components constituting the ceramic.
- the material of the support substrate 1 of this indication can be confirmed with the following method.
- XRD X-ray diffractometer
- the support substrate 1 is measured using an X-ray diffractometer (XRD: for example, D8 ADVANCE manufactured by Bruker AX), and the value of 2 ⁇ (2 ⁇ is a diffraction angle) obtained is identified with a JCPDS card.
- quantitative analysis of each component is performed using an ICP (Inductively Coupled Plasma) emission spectroscopic analyzer (ICP) or a fluorescent X-ray analyzer (XRF).
- ICP Inductively Coupled Plasma
- XRF fluorescent X-ray analyzer
- XRD if the presence of aluminum oxide is confirmed and the content converted from aluminum (Al) content measured by ICP or XRF to aluminum oxide (Al 2 O 3 ) is 70% by mass or more, oxidation Aluminum ceramics. The same applies to other ceramics.
- the first surface 1a of the support substrate 1 of the present disclosure has an arithmetic average roughness Ra obtained from the roughness curve of 0.5 ⁇ m or less and a skewness Rsk obtained from the roughness curve is negative.
- the arithmetic average roughness Ra is a value defined in JIS B 0601 (2013).
