Heterogeneous integration uses packaging technology to integrate dissimilar chips, LED, MEMS, VCSEL, etc. from different fabless houses and with different functions and wafer sizes into a single system or subsystem. How are these dissimilar chips and optical components supposed to talk to each other? The answer is redistribution layers (RDLs). This book addresses the fabrication of RDLs for heterogeneous integrations, and especially focuses on RDLs on: A) organic substrates, B) silicon substrates (through-silicon via (TSV)-interposers), C) silicon substrates (bridges), D) fan-out substrates, and E) ASIC, memory, LED, MEMS, and VCSEL systems. The book offers a valuable asset for researchers, engineers, and graduate students in the fields of semiconductor packaging, materials sciences, mechanical engineering, electronic engineering, telecommunications, networking, etc.

ABSTRACT
This study investigated the effects of the addition of coral rubble and polyvinylchloride (PVC) guttering as substrates on the growth of the donkey ear abalone (Haliotis asinina) reared in a How through water system. The tanks were 100 cm long x 50 cm wide x 40 cm deep, filled with sea water up to a height of 30 cm. Hatchery produced abalone, with a mean initial shell length of 30.9 i 0.1 mm and wet weight of 5.51: 0.1 g. were stocked at 25 individuals per tank that corresponds to stocking densities of ca. 50 abalone m'2 at the bottom of the tank. Juvenile abalone were provided with plenty of red seaweed Gracilaria spp daily over 175 days. The results show that the growth and growth rates in shell length and wet body weight were not significantly different between treatments (P>0.05). Survival rates of juveniles reared in the tank with the addition of coral rubble and/or PVC guttering were 100%, but 98% for juveniles in the tank without the addition of substrate. The average daily growth rates of shell length and wet body weight were 0.08710037 mm and 008810.044 g for juveniles reared in the tank with coral rubble 0.08110030 mm and 0.07710032 g for juveniles reared in the tank with PVC guttering and 008210.032 mm and 007810.039 g for juveniles reared in the tank without substrates. Juveniles reared in tanks with a flow through water system grew very well. The increase of body weight was more than double (>250%) the initial size.

[Parameter COD dan TDS merupakan dua parameter yang nilainya paling tinggi pada limbah susu yaitu dengan kisaran 1.000-8.000 mg/L untuk COD dan 1.000-4.000 mg/L untuk TDS. Penelitian ini dilakukan untuk menurunkan kedua nilai parameter tersebut menggunakan bioreaktor Microbial Fuel Cell (MFC) yaitu merupakan sebuah teknologi alternatif pengolahan limbah yang dapat mendegradasi kandungan organik limbah serta menghasilkan energi listrik secara langsung tanpa membutuhkan konversi dan untuk melihat potensi limbah susu secara teoritis dalam menghasilkan energi listrik Penelitian dilakukan selama 2 bulan dengan membuat reaktor. MFC skala laboratorium dengan jenis single chamber tanpa membran berukuran 16/L dengan dimensi 40/20/20 cm Terdapat penambahan bakteri Escherichia coli untuk meningkatkan degradasi kandungan organik limbah. Penelitian yang dilakukan secara batch ini menunjukkan efisiensi penurunan COD sebesar 51 pada waktu tinggal 13 hari sedangkan TDS mengalami peningkatan karena adanya penambahan larutan elektrolit. Dengan konsentrasi COD influen sebesar 3.853 mg/L penurunan rata rata COD dari total yang tersisihkan adalah 7.7 setiap harinya Limbah susu ini memiliki potensi untuk dijadikan substrat dalam reaktor MFC karena secara teoritis dapat menghasilkan arus maksimum sebesar 340 mA dengan efisiensi Coulomb sebesar 13 Hasil ini lebih besar dibandingkan dengan penelitian lain yang menggunakan limbah domestik sebagai substrat. ......COD and TDS are two parameters that have the highest value in dairy wastewater with a COD ranging between 1.000 and 8.000 mg/L and a TDS ranging between 1.000 and 4.000 mg/L. The aim of this study is to reduce the value of these parameters by using a Microbial Fuel Cell (MFC) bioreactor an alternative wastewater treatment technology that can degrade the organic content of the wastewater and produce electrical energy directly without the need of conversion and to see theoretically the dairy wastewater potential in power generation Research is done for 2 months by creating a laboratory scale MFC reactor with single chamber type without a membrane and has reactor volume of 16/L with dimensions of 40/20/20 cm. There is an addition of Escherichia coli bacteria to increase the degradation of the organic content of the wastewater Research which carried out in batch shows COD removal efficiency of 51 at the HRT of 13 days while TDS has increased due to the addition of an electrolyte solution As influent COD concentration is 3.853 mg/L the average decrease of the total excluded COD was 7.7 per day Therefore dairy wastewater has the potential to be used as a substrate in MFC reactor because theoretically it can produce a maximum current of 340 mA with Coulomb efficiency of 13. These result is greater than other research that use domestic wastewater as a substrate., COD and TDS are two parameters that have the highest value in dairy wastewater with a COD ranging between 1 000 and 8 000 mg L and a TDS ranging between 1 000 and 4 000 mg L The aim of this study is to reduce the value of these parameters by using a Microbial Fuel Cell MFC bioreactor an alternative wastewater treatment technology that can degrade the organic content of the wastewater and produce electrical energy directly without the need of conversion and to see theoretically the dairy wastewater potential in power generation Research is done for 2 months by creating a laboratory scale MFC reactor with single chamber type without a membrane and has reactor volume of 16 L with dimensions of 40 20 20 cm There is an addition of Escherichia coli bacteria to increase the degradation of the organic content of the wastewater Research which carried out in batch shows COD removal efficiency of 51 at the HRT of 13 days while TDS has increased due to the addition of an electrolyte solution As influent COD concentration is 3 853 mg L the average decrease of the total excluded COD was 7 7 per day Therefore dairy wastewater has the potential to be used as a substrate in MFC reactor because theoretically it can produce a maximum current of 340 mA with Coulomb efficiency of 13 These result is greater than other research that use domestic wastewater as a substrate ]
