The present invention relates to a photo mask and a method of manufacturing the same, and a method of forming a photosensitive film pattern using the photo mask. A photo mask pattern having an exposure region, a phase-inverse region and a photosensitive region is provided. The predetermined size and shape of the patterns on the photo mask are formed. Through this manner, distortions of the photosensitive film pattern upon development are compensated and a target photosensitive film pattern can be more accurately acquired. Furthermore, the depth of focus of a photolithography process can be increased.

A method of correcting a design pattern of a mask takes into account the overlay margin between adjacent one of actual patterns that are stacked on a substrate. First, a pattern of a photomask for forming a first one of the actual patterns on a substrate is conceived. Also, information representing the image of a second one of the actual patterns is produced. Then, optical proximity correction (OPC) is performed on the first pattern based on the information. The information may be obtained by simulating the transcription of a photomask having a second pattern designed to form the second actual pattern, or by forming the second actual pattern and then capturing the image of the second actual pattern. Accordingly, a sufficient margin is provided between the second actual pattern and the first pattern on which the optical proximity correction has been performed.

The present invention relates to a micro optical communication device package. The package of the invention comprises a Micro-Electro-Mechanical System (MEMS) chip for executing an optical communication function. The MEMS chip is mounted on a base. An upper housing having an opened bottom is placed on the base to form an internal space together with the base. The upper housing is sealed with the base to hermetically seal the MEMS chip within the internal space. The MEMS chip is connected an optical fiber, which is extended through the upper housing to form a light path. A boot is fit around the optical fiber and fixed to the upper housing to seal a portion of the upper housing for allowing passage of the optical fiber.

Disclosed is a digital image compression and decompression method and apparatus for dividing a supplied digital image signal into blocks of predetermined size, performing variable-length coding of the signal, separating the signal with respect to principle information and remaining information, and controlling the record format so that each type of information is alternately recorded on a recording medium in an equal interval whenever recording the compressed information and decompressing the information, according to the reverse order, during decoding. Also, the function for extracting an activity in two steps during coding and then controlling the permitted number of bits of the variable length coding is provided. Accordingly, the coding efficiency is improved and the circuitry is simplified so that the price of the end product can be lowered.
