Patent number: 6617195Abstract: A method of manufacturing a semiconductor device by attaching a flip chip die to an organic substrate using solder comprises applying no-clean flux to the flip chip die or the organic substrate; heating the flip chip die and the organic substrate to bond the flip chip die to the organic substrate, and cooling the flip chip die and the organic substrate. The step of heating the flux includes controlling oxygen and moisture content of an atmosphere surrounding the flux, preheating to a temperature of about 145° C. to about 165° C., soaking at a temperature of about 145° C. to about 165° C. for about four to about six minutes, and reflowing above the solder's melting point.Type: GrantFiled: July 24, 2000Date of Patent: September 9, 2003Assignee: Advanced Micro Devices, Inc.Inventors: Raj N. Master, Mohammad Z. Khan, Maria G. Guardado

Patent number: 6617196Abstract: A semiconductor device capable of improving the flexibility of designing electrical lead patterns for connection from chips via a substrate to external terminals by appropriately arranging the substrate structure and layout of more than one address signal as commonly shared by four separate chips is disclosed. In a surface mount type package of ball grid array (BGA), four chips 1 are mounted on a substrate 2 in such a manner such these are laid out in the form of an array of two rows and two columns. These four chips 1 are such that regarding the upper side and lower side, these are in linear symmetry with respect to a center line extending in a direction along long side edges of the substrate 2.Type: GrantFiled: December 21, 2001Date of Patent: September 9, 2003Assignees: Hitachi, Ltd., Akita Electronics Co., Ltd.Inventors: Akihiko Iwaya, Toshio Sugano, Susumu Hatano, Yutaka Kagaya, Masachika Masuda

Patent number: 6617197Abstract: A packaging arrangement is described that utilizes a conductive panel (such as a leadless leadframe) as its base. The conductive panel has a matrix of device areas that each include a plurality of rows of contacts that are located outside of a die area. Tie bars provide support for the various contacts. Some of the tie bars are arranged to extend between adjacent contacts in the same row and some of the tie bars are arranged to extend diagonally between associated contacts in adjacent rows that are not adjacent one another. During packaging, the tie bars can be severed by cutting along lines (e.g. saw streets) that run adjacent the rows after a molding operation. The described panels are particularly useful in packages having three or more rows of contacts.Type: GrantFiled: November 15, 2001Date of Patent: September 9, 2003Assignee: National Semiconductor CorporationInventors: Jaime Bayan, Peter Howard Spalding

Patent number: 6617198Abstract: Disclosed is a method for forming a semiconductor assembly and the resulting assembly in which a flowable adhesive material which secures a die to a support and does not form an adhesive fillet. A flowable adhesive is deposited between the die and support so that it covers about 50 to about 90 percent of the bottom surface area of the die after the die is mounted to the support. The reduced surface coverage area prevents formation of an adhesive fillet.Type: GrantFiled: July 23, 2001Date of Patent: September 9, 2003Assignee: Micron Technology, Inc.Inventor: Jerry M. Brooks

Patent number: 6617200Abstract: The present invention provides a semiconductor device that makes it possible to expose the back side of a die pad as well as a method for fabricating the same. The semiconductor device can include a lead frame that has portions to be sandwiched by first and second molds and a die pad that is down set at a distance greater than the depth of a recessed part of the first mold. The die pad is placed on the bottom of the recessed part of the first mold and the lead frame is disposed so that the portions to be sandwiched are suspended above the first mold. The molding process is carried out as the second mold presses the portions of the lead frame to be sandwiched in the direction of the first mold.Type: GrantFiled: June 29, 2001Date of Patent: September 9, 2003Assignee: Seiko Epson CorporationInventor: Masaaki Sone

Patent number: 6617201Abstract: An FBGA packaged device including a die adhered to a substrate with a small gap being formed between the die and substrate. An opening is formed through the substrate adjacent the center portion of the die. An encapsulating mold is formed around the die extending into the gap and also filling the channel. At least one barrier is disposed in the gap between the substrate and the die adjacent the channel to control the flow path of the encapsulating material as the mold is formed in the package.Type: GrantFiled: September 30, 2002Date of Patent: September 9, 2003Assignee: Micron Technology, Inc.Inventors: Lim T.
